Journal article (peer-reviewed)abstract
- The purpose was to investigate pre-operative symptoms and types of sport in competitive athletes undergoing arthroscopic treatment for femoroacetabular impingement syndrome (FAIS), and to compare between genders. Competitive athletes planned for arthroscopic treatment for FAIS were included prospectively in a hip arthroscopy registry. A total of 1548 athletes were identified and 919 were included. Sporting activity and patient-reported outcome measures (PROMs), including HSAS, iHOT-12, and HAGOS, were recorded, pre-operatively. The study comprised 738 male and 181 female athletes (median age 25; interquartile range 20-32 years) who had undergone arthroscopic treatment for FAIS. The most common sports type performed by males were football (48%) and ice hockey (19%) and in females, football (25%) and horseback riding (22%). Females reported a significantly longer duration of symptoms (median 36 vs 24 months) and lower pre-operative scores for the iHOT-12 and all the HAGOS subscales, except for physical activity. In conclusion, horseback riding and football are almost equally common in female athletes, while football is by far the most common in male athletes, who underwent arthroscopic treatment for FAIS. Females had a longer duration of symptoms and a higher degree of self-reported symptoms and dysfunction prior to the hip arthroscopy.

Journal article (peer-reviewed)abstract
- Purpose: The aim was to investigate the rate of athletes still active at their pre-injury sports level two years after arthroscopic treatment for femoroacetabular impingement syndrome (FAIS), and examine this between different sports and gender, and its correlation to patient-reported outcome measures (PROMs). Method: High-level athletes planned for arthroscopic treatment for FAIS were included prospectively in a Swedish hip arthroscopy registry between 2011 and 2017, and 717 met the inclusion criteria. Self-reported sporting activity was recorded preoperatively. The subjects answered PROMs, including the HSAS, iHOT-12 and HAGOS pre- and postoperatively. Results: A total of 551 athletes (median age 26, interquartile range 20–34 years; 23% women) had completed follow-up PROMs, at mean 23.4 ± 7.2 months postoperatively. In total, 135 (24.5%) were active at their pre-injury level of sports at follow-up (RTSpre). Athletes ≤30 years at time of surgery (n = 366; median age 22 years) had higher rate of RTSpre (31.4%) compared with athletes > 30 years (n = 185; median age 40 years) (10.8%; p < 0.001). All athletes had improvements in iHOT-12 and HAGOS, two years postoperatively (p < 0.001), while RTSpre athletes reported significantly better PROMs, pre- and postoperatively, and had greater improvements two years postoperatively, compared with athletes not active at pre-injury level. Conclusion: Only 25% of all high-level athletes and 31% of athletes ≤30 years were still active at their pre-injury sports level two years after arthroscopic treatment for FAIS. Athletes still active had significantly and clinically greater improvement regarding hip symptoms, function and quality of life, as compared with athletes not active at pre-injury level, two years postoperatively. © 2020, The Author(s).

Good functional outcomes after endoscopic treatment for greater trochanteric pain syndrome
- 2023
-
In: Journal of Experimental Orthopaedics. - : Springer Science and Business Media LLC. - 2197-1153. ; 10:1
-
Journal article (peer-reviewed)abstract
- Purpose: Greater trochanteric pain syndrome (GTPS) is a term covering different conditions generating lateral hip pain. Recalcitrant cases may require surgery but there are only a few studies evaluating endoscopic treatment. This study aimed to evaluate the outcome of endoscopically treated GTPS at minimum two years postoperatively using patient-reported outcome measures (PROMs), and to assess the complication rate associated with endoscopic surgery. Methods: A total of 33 patients, mean age 43.2years, 88% women, with a mean symptom duration of 3.5years, were included in the study. A total of 36 operated hips were included. Pre- and at minimum two years postoperatively the patients completed questionnaires consisting of the International Hip Outcome Tool (iHOT-12) and the Hip Sports Activity scale (HSAS), the Visual analogue scale for overall hip function (VAS-OHF), the Copenhagen Hip and Groin Outcome Score (HAGOS), the EuroQoL-5 Dimension Questionnaire (EQ-5D) and the EQ-VAS. Complications were assessed using the Clavien-Dindo classification. Results: Median follow-up time was 24.5months postoperatively. Statistically significant improvements were seen for the following PROMs (p < 0.05); iHOT-12 (36.3 vs 54.0), HAGOS different subscores (40.8 vs 59.0, 46.5 vs 62.6, 29.9 vs 53.1, 33.5 vs 51.4, 20.7 vs 41.4, 23.4 vs 43.3), EQ-VAS (55.9 vs 63.3) and EQ-5D (0.392 vs 0.648). VAS-OHF and HSAS did not reach significance. There was a 71% satisfaction rate with the surgery. Three Clavien-Dindo grade 1 and one grade 2 complications were registered postoperatively, with 41% of patients achieving PASS for iHOT-12 at two years follow-up. Conclusion: Endoscopic surgery for greater trochanteric pain syndrome improved patient-reported outcomes and the procedure was associated with low risk of complications. Level of evidence: Level IV.

Evaluation of outcome reporting trends for femoroacetabular impingement syndrome- a systematic review
- 2021
-
In: Journal of Experimental Orthopaedics. - : Springer Science and Business Media LLC. - 2197-1153. ; 8:1
-
Journal article (peer-reviewed)abstract
- Purpose: The aim of this systematic review was to evaluate the trends in the literature regarding surgical treatment for femoroacetabular impingement syndrome (FAIS) and to present which patient-reported outcome-measures (PROMs) and surgical approaches are included. Methods: This systematic review was conducted with the PRISMA guidelines. The literature search was performed on PubMed and Embase, covering studies from 1999 to 2020. Inclusion criteria were clinical studies with surgical treatment for FAIS, the use of PROMs as evaluation tool and studies in English. Exclusion criteria were studies with patients < 18years, cohorts with < 8 patients, studies with primarily purpose to evaluate other diagnoses than FAIS and studies with radiographs as only outcomes without using PROMs. Data extracted were author, year, surgical intervention, type of study, level of evidence, demographics of included patients, and PROMs. Results: The initial search yielded 2,559 studies, of which 196 were included. There was an increase of 2,043% in the number of studies from the first to the last five years (2004–2008)—(2016–2020). There were 135 (69%) retrospective, 55 (28%) prospective and 6 (3%) Randomized Controlled Trials. Level of evidence ranged from I-IV where Level III was most common (44%). More than half of the studies (58%) originated from USA. Arthroscopic surgery was the most common surgical treatment (85%). Mean follow-up was 27.0months (± 17 SD), (range 1.5–120months). Between 1–10 PROMs were included, and the modified Harris Hip Score (mHHS) was most commonly used (61%). Conclusion: There has been a continuous increase in the number of published studies regarding FAIS with the majority evaluating arthroscopic surgery. The mHHS remains being the most commonly used PROM. © 2021, The Author(s).

Journal article (peer-reviewed)abstract
- © 2020 The Author(s). Background: Femoroacetabular impingement syndrome (FAIS) is a common cause of hip pain and disability in athletes. Arthroscopic treatment for FAIS is well-established; however, the long-term results in elite athletes are limited. Purpose: To evaluate outcomes 5 years after arthroscopic treatment for FAIS in elite athletes. Study Design: Case series; Level of evidence, 4. Methods: Elite athletes undergoing arthroscopic treatment for FAIS with a minimum 5-year follow-up were included. They were prospectively followed up with patient-reported outcome measures. An elite athlete was defined as having a Hip Sports Activity Scale (HSAS) level of 7 or 8 before the onset of symptoms. Preoperatively and 5 years after surgery, all athletes completed a web-based questionnaire, including the Copenhagen Hip and Groin Outcome Score (comprising 6 subscales), the EQ-5D and EQ-VAS (European Quality of Life–5 Dimensions Questionnaire and European Quality of Life–Visual Analog Scale), iHOT-12 (International Hip Outcome Tool), a visual analog scale for hip function, and the HSAS. Moreover, patients reported their overall satisfaction with their hip function. Preoperative measurements were compared with the 5-year follow-up. Results: A total of 64 elite athletes (52 men, 12 women) with a mean ± SD age of 24 ± 6 years were included. On average, patients reported a statistically significant and clinically relevant improvement from preoperative patient-reported outcome measures to the 5-year follow-up (P <.0003), Copenhagen Hip and Groin Outcome Score subscales (symptoms, 51.7 vs 71.9; pain, 61.0 vs 81.1; function of daily living, 67.1 vs 83.6; function in sports and recreation, 40.0 vs 71.5; participation in physical activity, 25.0 vs 67.4; hip and groin–related quality of life, 34.4 vs 68.0), EQ-5D (0.60 vs 0.83), EQ-VAS (66.1 vs 76.7), and iHOT-12 (40.0 vs 68.8). At the 5-year follow-up, 90.5% reported satisfaction with their overall hip function. In total, 54% still participated in competitive sports (HSAS, 5-8) at follow-up, while 77% had decreased their level. Older patients and patients with longer duration of symptoms reported a significantly lower level of sports activity (HSAS, 0-4; P <.009). Conclusion: Arthroscopic treatment for FAIS in elite athletes results in a statistically significant and clinically relevant improvement regarding symptoms, hip function, quality of life, and pain 5 years after surgery. Approximately half of the cohort was still in competitive sports at follow-up, yet 77% had decreased their level of sports. Nine of 10 patients were satisfied with their surgery.

Improvements After Arthroscopic Treatment for Femoroacetabular Impingement Syndrome in High-Level Ice Hockey Players : 2-Year Outcomes by Player Position
- 2021
-
In: Orthopaedic Journal of Sports Medicine. - : SAGE Publications. - 2325-9671. ; 9:3
-
Journal article (peer-reviewed)abstract
- Background: Ice hockey players often undergo arthroscopic treatment for femoroacetabular impingement syndrome (FAIS); however, only a few studies have reported postoperative patient-reported outcomes. It has been debated whether player position is related to FAIS. Purpose: To evaluate the change in patient-reported outcome measures (PROMs) in high-level ice hockey players from presurgery to 2 years after arthroscopic treatment for FAIS. The secondary aim was to evaluate differences in outcomes among player positions and whether stick handedness is related to the side of the symptomatic hip. Study Design: Case series; Level of evidence, 4. Methods: Ice hockey players undergoing treatment for FAIS between 2011 and 2019 were prospectively included. Preoperative and 2-year follow-up scores were collected for the following PROMs: HAGOS (Copenhagen Hip and Groin Outcome Score), iHOT-12 (12-item International Hip Outcome Tool), EQ-5D (EuroQol–5 Dimensions) and EQ-VAS (EuroQol–Visual Analog Scale), Hip Sports Activity Scale, and visual analog scale for overall hip function. Player position and stick handedness were collected from public sources. Preoperative and follow-up outcomes were compared for the entire cohort and among player positions. Results: The cohort included 172 ice hockey players with a mean age of 28 years, a mean body mass index of 25.6, and a mean symptom duration of 46.3 months. In the 120 players with 2-year follow-up data, there was significant improvement in all PROMs as compared with presurgery: HAGOS subscales (symptoms, 47.5 vs 68.0; pain, 57.0 vs 75.8; activities of daily living, 62.5 vs 81.0; sports, 40.0 vs 64.7; physical activity, 30.9 vs 57.2; quality of life, 32.5 vs 57.8), iHOT-12 (45.2 vs 66.7), EQ-5D (0.59 vs 0.75), EQ-VAS (68.3 vs 73.2), and visual analog scale for overall hip function (49.6 vs 69.2) (P <.0001 for all). At 2-year follow-up, 83% reported satisfaction with the procedure. There was no difference in the improvement in PROMs among player positions. Further, there was no significant relationship between stick handedness and side of symptomatic hip; however, because of the number of bilateral procedures and large number of left-handed shooters, no conclusions could be drawn. Conclusion: High-level ice hockey players undergoing arthroscopic treatment for FAIS reported improvements in PROMs 2 years after surgery, regardless of player position.

Loss to follow-up: initial non-responders do not differ from responders in terms of 2-year outcome in a hip arthroscopy registry.
- 2020
-
In: Journal of hip preservation surgery. - : Oxford University Press (OUP). - 2054-8397. ; 7:2, s. 281-287
-
Journal article (peer-reviewed)abstract
- Loss to follow-up in registry studies is a problem due to potential selection bias. There is no consensus on the effect of response rate. The aim of this study was to compare patient-reported outcome measures (PROMs) between responders and initial non-responders (INR) in a hip arthroscopy registry and to examine whether demographics affect the response rate. Data from hip arthroscopies performed at two centres in Gothenburg were collected and the patients were followed up with PROMs. The follow-up was a minimum of 2 years after surgery. All 536 patients who underwent primary hip arthroscopies during 2015 and 2016 and had recorded pre-operative PROMs were included. A total of 396 patients completed the follow-up and were labelled 'Responders' (R) and 107 patients responded after reminders were sent and labelled 'Initial non-responders' (INR). The mean time of follow-up was 24.7±2.9 and 42.5±7.0months for the R- and INR-group, respectively. There were no differences between the two groups at the follow-up for the Copenhagen Hip and Groin Outcome Score, European Quality of life 5 dimensions questionnaire, EQ-VAS, International Hip Outcome Tool or a visual analogue scale for hip function. A larger proportion of R was satisfied after hip arthroscopy compared with INR (86% versus 70%, P=0.0003). INR were younger than responders (31.5±12.5 versus 35.6±12.7years of age). The conclusion of the study was that there were no differences between R and INR at the follow-up across the PROMs except patient satisfaction, where responders were more satisfied.

Prior hip arthroscopy does not affect 1-year patient-reported outcomes following total hip arthroplasty: a register-based matched case-control study of 675 patients
- 2021
-
In: Acta Orthopaedica. - : Medical Journals Sweden AB. - 1745-3674 .- 1745-3682. ; 92:4, s. 408-412
-
Journal article (peer-reviewed)abstract
- Background and purpose - Femoroacetabular impingement syndrome (FAIS) is a common cause of hip pain and may contribute to the development of osteoarthritis. We investigated whether a prior hip arthroscopy affects the patient-reported outcomes (PROMs) of a later total hip arthroplasty (THA). Patients and methods - Patients undergoing hip arthroscopy between 2011 and 2018 were identified from a hip arthroscopy register and linked to the Swedish Hip Arthroplasty Register (SHAR). A propensity-score matched control group without a prior hip arthroscopy, based on demographic data and preoperative score from the EuroQoL visual analogue scale (EQ VAS) and hip pain score, was identified from SHAR. The group with a hip arthroscopy (treated group) consisted of 135 patients and the matched control group comprised 540 patients. The included PROMs were EQ-5D and EQ VAS of the EuroQoL group, and a questionnaire regarding hip pain and another addressing satisfaction. Rate of reoperation was collected from the SHAR. The follow-up period was 1 year. Results - The mean interval from arthroscopy to THA was 27 months (SD 19). The EQ-5D was 0.81 and 0.82, and EQ VAS was 78 and 79 in the treated group and the matched control group respectively. There were no differences in hip pain, and reported satisfaction was similar with 87% in the treated group and 86% in the matched control group. Interpretation - These results offer reassurance that a prior hip arthroscopy for FAIS does not appear to affect the short-term patient-reported outcomes of a future THA and indicate that patients undergoing an intervention are not at risk of inferior results due to their prior hip arthroscopy.

Return to Sport for Professional and Subelite Ice Hockey Players After Arthroscopic Surgery for Femoroacetabular Impingement Syndrome
- 2022
-
In: Orthopaedic Journal of Sports Medicine. - : SAGE Publications. - 2325-9671 .- 2325-9671. ; 10:5
-
Journal article (peer-reviewed)abstract
- Background: Femoroacetabular impingement syndrome (FAIS) is a common cause of hip pain, which can prevent ice hockey players from sports participation. Hip arthroscopy is often performed to relieve pain and enable the player to return to sport (RTS) and return to performance (RTP). Purpose: To determine the RTS and RTP rates for ice hockey players at the professional and subelite levels after hip arthroscopy for FAIS. Study Design: Case series; Level of evidence, 4. Methods: High-level ice hockey players who underwent hip arthroscopy for FAIS between 2011 and 2019 were identified using a local hip arthroscopy registry. The player's level was confirmed with ice hockey-specific web pages and was stratified as subelite or professional. Data on the players' careers were extracted from these web pages. Player position was divided into goalkeepers, defensemen, and forwards. Data on participation in games included the season before onset of symptoms, the season before surgery, and the first and second seasons after surgery. RTS was defined as returning to ice hockey after surgery, and RTP was considered as returning to the same league at a comparable level to before symptoms. Results: A total of 80 ice hockey players were included. Comparing presymptom performance with the first season after surgery, the RTS rate was 72%, of which 94% of the players returned to the same or higher level of play. Comparing the presurgery season with the first season after surgery, the RTS rate was 78%. At the second season after surgery, 64% of players still played ice hockey, with a significantly higher return rate among professional players compared with subelite players (96% vs 69%; P = .014). Overall, 85% goalkeepers, 74% forwards, and 60% defensemen returned to sport. Only 28% played at least the same number of games during the first season after surgery as they did during the presymptom season. Conclusion: High-level ice hockey players who underwent hip arthroscopy for FAIS had a high RTS rate, in which the majority returned to the same league. However, only 28% played the same number of games the first season after surgery as they did at the presymptom level. Professional ice hockey players returned more frequently than players on the subelite level.

Self-Reported Level of Sports Compared With Objective Data in Athletes With Femoroacetabular Impingement Syndrome
- 2024
-
In: AMERICAN JOURNAL OF SPORTS MEDICINE. - 0363-5465 .- 1552-3365.
-
Journal article (peer-reviewed)abstract
- Background: Femoroacetabular impingement syndrome (FAIS) is common among ice hockey and soccer players. To evaluate the prevalence of return to sports after hip arthroscopy or level of sports before surgery, self-reported questionnaires such as the Hip Sports Activity Scale (HSAS) are frequently used. There is a risk of self-reporting bias when using these tools.Purpose: To evaluate how self-reported levels of sports using HSAS correspond to objective data.Study Design: Cohort study, Level of evidence: 3.Method: Ice hockey and soccer players undergoing hip arthroscopy for FAIS between 2011 and 2019 and included in the local hip arthroscopy registry in Gothenburg, Sweden, aged >= 18 years at the time of surgery, with a self-reported HSAS level of 7 or 8 before onset of symptoms, were included. Objective data on level of sports were collected through sports-specific sources (https://football.instatscout.com, https://hockey.instatscout.com, https://www.eliteprospects.com, and Swedish Football Association). Objective data were collected for the corresponding season when the athletes reported their symptom onset. Agreement between subjective and objective data was described using descriptive statistics, and comparison between subgroups was made.Results: A total of 483 athletes met the inclusion criteria: 80 ice hockey and 403 soccer players. The majority were men (90%). The mean age was 26.5 years (SD, 8.3 years). When comparing HSAS level with objective data, 112 athletes (23%) had a correct self-reported HSAS level. Of 251 athletes with a self-reported HSAS level of 8, 76 (30%) had a matching objective HSAS level, and 36 of 232 (16%) athletes with a self-reported HSAS level of 7 had a matching objective HSAS level. Of the erroneous subjective ratings, 98% were higher than the objective data. Athletes reporting a correct HSAS level were younger (24.6 vs 26.4 years; P = .04) and had a shorter symptom duration (18 vs 24 months; P < .001). Ice hockey players scored themselves correctly more often than soccer players (P < .001).Conclusion: Only 23% of athletes undergoing hip arthroscopy for FAIS self-reported an HSAS level before onset of symptoms that was accurate according to the objectively recorded data. The majority self-reported an HSAS level above their correct level of sports. Ice hockey players, younger age, and shorter symptom duration were associated with correct self-assessment.

Journal article (peer-reviewed)abstract
- PurposeTo evaluate the outcome of arthroscopic treatment for iliopsoas impingement after total hip arthroplasty (THA) 2 years after surgery using patient reported outcomes (PROM).MethodsIn this study 12 patients (13 hips) were included from a local hip arthroscopy registry. Patients completed web-based PROMs preoperatively and at a minimum of 2 years postoperatively. The PROMs included the International Hip Outcome Tool short version (iHOT-12), the Copenhagen Hip and Groin Outcome Score (HAGOS), the European Quality of Life-5 Dimensions Questionnaire (EQ-5D), the Hip Sports Activity Scale (HSAS) for physical activity level, the Visual Analog Scale (VAS) for overall hip function and a single question regarding overall satisfaction with the surgery.ResultsThe mean age was 64.4 years (+/- 15.1SD), mean body mass index (BMI) was 26.6 (+/- 4.3SD), mean follow-up time was 49.8 months (+/- 25SD). Comparing PROMs preoperatively with 2-year follow up showed an improvement for many of the PROMs used. The PROMs scores were iHOT-12 (24.9 vs 34.5, p = 0.13), HAGOS subscales (symptoms 38.2 vs 54.5, p = 0.05; pain 36 vs 53, p = 0.04; sport 14.1 vs 35.1, p = 0.03; daily activity 31 vs 47.5, p = 0.04; physical activity 21.8 vs 24, p = 0.76; quality of life 24 vs 35, p = 0.03), EQ-VAS (57.9 vs 58, p = 0.08), EQ-5D (0.34 vs 0.13, p = 0.07) and VAS for overall hip function (43.1 vs 46.2, p = 0.14). In total, 10 out of the 12 patients (83%) were satisfied with the intervention.ConclusionPatients undergoing surgery for iliopsoas impingement after previous THA showed improved self-reported hip function where most patients were satisfied with treatment.

Journal article (peer-reviewed)abstract
- Femoroacetabular impingement (FAI) is a common cause of hip pain and dysfunction. The purpose of this study was to report outcome 2years after the arthroscopic treatment of FAI using validated outcome measurements. Two hundred and eighty-nine patients (males=190, females=99) with a mean age of 37years underwent arthroscopic surgery for FAI. Patients were included consecutively in a hip arthroscopy registry. The cohort was evaluated using online web-based validated health-related patient-reported outcomes measurements, including the iHOT-12, HAGOS, EQ-5D, HSAS for physical activity level, VAS for overall hip function and overall satisfaction. The mean follow-up time was 25.4months. Pre-operative scores compared with those obtained at follow-up revealed statistically and clinically significant improvements (P<0.05) for all measured outcomes; iHOT-12 (43 vs 66), VAS for global hip function (50 vs 71), HSAS (2.9 vs 3.6), EQ-5D index (0.58 vs 0.75), EQ-VAS (67 vs 75) and HAGOS different subscales (56 vs 76, 51 vs 69, 60 vs 78, 40 vs 65, 29 vs 57, 33 vs 58). At the 2-year follow-up, 236 patients (82%) reported they were satisfied with the outcome of surgery. We conclude that arthroscopic treatment for FAI resulted in statistically and clinically significant improvements in outcome parameters.

Journal article (peer-reviewed)abstract
- PurposeFemoroacetabular impingement syndrome (FAIS) is a known cause of impaired sports performance in athletes and the relationship between FAIS and soccer players has previously been described. Hip arthroscopy is a viable treatment option that can facilitate athletes' return to sport (RTS). The aim of this study was to evaluate the RTS and return to performance (RTP) with objective measurements in high-level soccer players after hip arthroscopy for FAIS.MethodSoccer players, with a hip sports activity scale (HSAS) level of 7 or 8 before symptom onset and undergoing hip arthroscopy for FAIS between 2011 and 2019 were identified in the Gothenburg hip arthroscopic registry. A total of 83 high-level soccer players, with a mean age of 23.9 (SD 4.4) years at surgery, were included. To verify the activity level and further stratify players as elite or sub-elite, player statistics were collected from soccer-specific scout webpages and the Swedish national soccer association. The return to sport was defined as return to one game of soccer. Return to performance was defined as playing at the same level, or higher, and participating in at least 80% of the number of games played the season before symptom onset or the season before surgery either the first or second season after hip arthroscopy.ResultsIn total, 71 (85.5%, 95% confidence interval (CI) 76.1-92.3%) of the players returned to sport the first or second season after surgery. Compared to the season before symptom onset, 31 (37.3%, 95% CI 27.0-48.7%) players returned to performance the first or second season after surgery, and 32 (38.6%, 95% CI 28.1-49.9%) players returned to performance the first or second season after surgery compared to the season before surgery.ConclusionA high rate of elite and sub-elite soccer players return to soccer after hip arthroscopy for FAIS. However, less than half of the players RTP when evaluating performance through level of play and number of games played.

- Purpose: To evaluate the 2-year outcomes after arthroscopic surgical treatment for femoroacetabular impingement syndrome (FAIS) using validated patient-reported outcome measurements in young elite athletes and to report the rate of return to sport. Methods: Young elite athletes undergoing arthroscopic surgery for FAIS with 2 years of follow-up were included. A young elite athlete was defined as an athlete aged 18 to 22 years at the time of surgery with a Hip Sports Activity Scale (HSAS) level greater than 6 before the onset of symptoms. The following patient-reported outcome measurements were collected prospectively: Copenhagen Hip and Groin Outcome Score, 12-item International Hip Outcome Tool, HSAS, visual analog scale (VAS), European Quality of Life (EQ) 5 Dimensions questionnaire, and EQ VAS. Furthermore, the patients answered a question related to satisfaction with surgery at follow-up. Results: A total of 84 athletes (67 male and 17 female athletes), with a mean age of 19.8 ± 1.5 years, completed the 2-year follow-up. Bilateral hip arthroscopy was performed in 57 athletes, generating a total of 141 included hips. The improvements in the Copenhagen Hip and Groin Outcome Score subscales, 12-item International Hip Outcome Tool, EQ 5 Dimensions questionnaire, EQ VAS, and VAS for overall hip function were statistically significant (P < .001). At the 2-year follow-up, 42% of the athletes reported an HSAS level of either 7 or 8 whereas 28% reported an HSAS level of 5 or 6. In total, 79% of the athletes were satisfied with the surgical procedure. Conclusions: There are significant improvements in outcome measurements at the 2-year follow-up in elite young athletes undergoing arthroscopic hip surgery for FAIS. Although many of the athletes remained in high-level sports 2 years after surgery, only 30% of the athletes returned to sport at the same level. Level of Evidence: Level IV, therapeutic case series. © 2022 The Authors

- Purpose: The purpose of this case report is to present the successful management of symptomatic bilateral femoroacetabular impingement (FAI) syndrome in a patient who underwent surgical treatment on one side and non-surgical treatment on the other side. Methods: We evaluated the treatment outcome of a young female presenting with bilateral FAI syndrome of cam morphology. A follow-up was performed at 5 years following surgical treatment on the right hip and 2 years following non-surgical treatment on the left hip. The evaluation included a clinical examination, patient-reported outcome measurements (PROM), plain radiographs, and magnetic resonance imaging (MRI). Results: The patient experienced subjective improvements bilaterally. The clinical examination revealed differences in range of motion between the surgically treated and the non-surgically treated sides, with internal rotation differing the most (20 degrees vs almost 0 degrees). Flexion was, however, the same on both sides (125 degrees). The PROM results were satisfactory on both sides, with slightly better results for the surgically treated side (the short version of the International Hip Outcome Tool [iHOT-12]: 96.9 vs 90, the Copenhagen Hip and Groin Outcome Score [HAGOS]: 90-100 vs 65-100). On the surgically treated side, the alpha angle decreased by 19 degrees postoperatively. An MRI did not reveal any injury to the cartilage or labrum on either side. Conclusion: This patient with bilateral FAI syndrome treated with arthroscopic surgery on one side and physiotherapy together with reduced physical activity on the other side, presented with good results bilaterally at follow-up.

Purpose: The purpose of the present study was to evaluate the outcome of arthroscopic treatment for femoroacetabular impingement (FAI) syndrome 5 years post-surgery using patient-reported outcome scores (PROMs) validated for a young and active population with hip complaints. Methods: Patients were prospectively included in the study. A total of 184 patients [males = 110 (59.8%), females = 74 (40.2%)], with mean age 38.0, underwent arthroscopic treatment for FAI syndrome and were analysed. Preoperatively and at the 5-year follow-up, patients completed a set of self-administered web-based PROMs consisting of the International Hip Outcome Tool (iHOT-12), the Copenhagen Hip and Groin Outcome Score (HAGOS), the Hip Sports Activity Scale (HSAS), the EuroQoL-5 Dimension Questionnaire (EQ-5D), the EQ-Visual Analogue Scale (VAS) and the VAS for overall hip function and overall satisfaction. The Wilcoxon signed rank test was used to compare preoperative PROM values with those obtained at the 5-year follow-up. Results: A comparison of preoperative PROM scores and those obtained at the 5-year follow-up revealed statistically significant improvements for all outcome scores (p < 0.05), except for the HSAS score, which were unchanged; iHOT-12 (42.9 vs 67.2), HAGOS different subscales (50.2 vs 69.6, 55.7 vs 76.1, 59.2 vs 72.3, 41.1 vs 66.4, 30.8 vs 60.2, 31.6 vs 60.4), EQ-5D (0.570 vs 0.742), EQ-VAS (66.6 vs 74.4), HSAS (3.13 vs 3.17) and VAS for overall hip function (47.9 vs 69.2). At the 5-year follow-up, 154 patients reported that they were satisfied with surgery (84.6%). Survivorship at the 5-year follow-up was 86.4%. Conclusion: Arthroscopic treatment for FAI syndrome yields good patient-reported outcome at the 5-year follow-up. Level of evidence: II.

Journal article (peer-reviewed)abstract
- Purpose The femoroacetabular impingement randomised controlled trial (FIRST) is a multi-center randomized controlled trial (RCT), comparing arthroscopic osteochondroplasty with arthroscopic lavage in adults aged 18-50 years diagnosed with non-arthritic femoroacetabular impingement (FAI) syndrome. The purpose of the present study is to report the prevalence, distribution and severity of adverse events during and within 24-month follow-up period. Methods Of the 220 patients included, 6 were adjudicated as ineligible, for a total of 214 patients included in the final analysis. An independent Adjudication Committee evaluated operatively treated and non-operatively treated adverse events that were related to the hip. Adverse events were also reported directly by each participating clinical site. Continuous variables were reported as mean and standard deviation, categorical variables were reported as counts and percentages. Results There were a total of 52 (24.2%, 52/214) adverse events in 46 (21.5%) patients (mean age 34.2 +/- 7.9 years, 58.7% male) during the 24-month follow-up. There were 12.6% (27/214) operatively treated adverse events for: hip pain, re-injury of labrum and heterotopic ossification. There were 11.7% (25/214) non-operatively treated adverse events for predominantly: hip pain, hip tendinopathy and hip popping/snapping. Approximately, 87% of adverse events resolved within the 24-month follow-up time. Conclusion Given the inherent challenges with conducting RCTs, the results of this adverse event study from the FIRST trial demonstrate that it is safe to perform an RCT addressing FAI syndrome.

Predictors of outcome at 2-year follow-up after arthroscopic treatment of femoro-acetabular impingement
- 2017
-
In: Journal of Hip Preservation Surgery. - : Oxford University Press (OUP). - 2054-8397. ; 4:3, s. 224-230

Journal article (peer-reviewed)abstract
- Femoro-acetabular impingement (FAI) is a common cause of hip pain and dysfunction in the young and active population. Despite reports of good short-term outcomes following treatment for FAI, less is known about the possible preoperative predictors of treatment outcome. The purpose of this study was to identify predictors of treatment outcome, using a patient-reported outcome measurement score (PROM) validated for use in a young and active population undergoing arthroscopic surgery for FAI. Patients were prospectively enrolled and analysed using the PROM International Hip Outcome Tool (iHOT-12) preoperatively and at a 2-year follow-up. Predictors of treatment outcome chosen for analysis were age, gender, duration of symptoms until surgery, level of cartilage damage, preoperative score and FAI type. A total of 198 patients, 122 males and 76 females (M: 61.6%, F: 38.4%), with a mean age of 41±12.1 years, were analysed. The preoperative iHOT-12 score correlated with the postoperative iHOT-12 score at the 2-year follow-up. For one iHOT-12 point positive difference preoperatively, an additional 0.65 points were gained postoperatively at the 2-year follow-up (P≤0.001). Age, gender, symptom duration until surgery, level of cartilage damage and FAI type did not have a statistically significant correlation to the postoperative score. Preoperative hip function as measured by the iHOT-12 is a potential predictor of outcome following FAI surgery relative to other factors.

Protocol for a multicenter prospective cohort study evaluating arthroscopic and non-surgical treatment for microinstability of the hip joint
- 2022
-
In: BMC Musculoskeletal Disorders. - : Springer Science and Business Media LLC. - 1471-2474. ; 23:1
-
Journal article (peer-reviewed)abstract
- Background: Microinstability of the hip joint is a proposed cause of hip pain and reduced function in young individuals. The underlying mechanism is thought to be extraphysiological hip motion due to bony deficiency and/or soft tissue deficiency or decreased soft tissue function. Recently, the condition has gained increased attention, and despite the fact that treatment today includes both non-surgical and surgical approaches, there is limited evidence on diagnostic specificity and treatment effects. The aim of this study is to evaluate clinical outcomes of both nonsurgical and surgical treatment for microinstability of the hip joint. Methods: A multicenter prospective cohort study is planned to evaluating the outcome of physical therapy aimed at stabilizing the hip joint, as well as arthroscopic plication of the hip joint capsule, if the physical therapy fails. Outcomes will be evaluated using hip-specific patient-reported outcome measures: the short version of the International Hip Outcome Tool and the Copenhagen Hip and Groin Outcome Score, strength and function tests, health-related quality of life as determined using the European Quality of Life-5 Dimensions and the European Quality of Life-Visual Analog Scale, sports activity levels according to the Hip Sport Activity Scale, and reported complications. Patients will be evaluated at 6, 12 and 24 months after each treatment. Discussion: It is important to evaluate the clinical outcomes of both non-surgical and surgical treatment for suspected microinstability of the hip joint, and the planned prospective evaluation will contribute to the understanding of non-surgical as well as surgical treatment outcomes, including complications.

Quality Assessment of Prospective Cohort Studies Evaluating Arthroscopic Treatment for Femoroacetabular Impingement Syndrome: A Systematic Review
- 2019
-
In: Orthopaedic Journal of Sports Medicine. - : SAGE Publications. - 2325-9671. ; 7:5
-
Research review (peer-reviewed)abstract
- Background: Femoroacetabular impingement (FAI) syndrome is a cause of pain and reduced range of motion in the hip joint. Given the limited number of randomized controlled trials, prospective cohort studies constitute the dominant part of the available prospective evidence evaluating relevant clinical outcomes after arthroscopic hip surgery for FAI. Purpose: To assess the methodological quality of prospective cohort studies evaluating arthroscopic surgery for FAI and to determine whether there has been an improvement in methodological quality over time. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic literature search was performed in PubMed, Embase (OvidSP), and the Cochrane Library. Included studies were clinical prospective cohort studies of primary arthroscopic surgery for cam and/or pincer morphology FAI. Methodological quality was assessed with the Methodological Index for Non-randomized Studies (MINORS). The mean MINORS score for studies published during the first 5 years of the period was compared with those published during the last 5 years to evaluate methodological improvement over time. The methodological quality of randomized controlled trials was also assessed with the Coleman Methodology Score. Results: The search yielded 53 studies. There were 34 noncomparative studies, 15 nonrandomized comparative studies, and 4 randomized controlled trials. The included studies were published between 2008 and 2017. The mean +/- SD MINORS score for noncomparative and comparative studies was 10.4 +/- 1.4 of 16 possible and 18.7 +/- 2.0 of 24 possible, respectively. The mean Coleman Methodology Score for randomized controlled trials was 79.0 +/- 7.0 of 100 possible. Conclusion: The methodological quality of prospective cohort studies evaluating arthroscopic surgery for FAI is moderate for comparative and noncomparative studies. Common areas for improvement include unbiased assessment of study endpoints and prospective sample-size calculations. Despite an increase in the number of published studies, an improvement in methodological quality over time was not observed.

The evolution of femoroacetabular impingement surgical management as a model for introducing new surgical techniques
- 2020
-

Journal article (peer-reviewed)abstract
- Introducing new surgical techniques and concepts can be difficult. There are many hurdles to overcome initially, such as the learning curve, equipment and technique development, before a standard of care can be established. In the past, new surgical techniques have been developed, and even widely accepted, before any scientific evaluation has been made. At that stage, it may be too late properly to evaluate the effectiveness of treatments, as the objectiveness and/or randomisation process may be obstructed. Since the introduction of evidence-based medicine (EBM), there have been high standards of scientific rigour to prove the efficacy of treatments. Based on the nature of evidence-based acceptance, innovations cannot be subjected to this final process before their evolution process is complete and, as a result, there is a need for the staged scientific development of new surgical techniques that should be adopted. This paper presents a model for this kind of stepwise introduction based on the actual evolution of FAI syndrome surgery. By following a scientific algorithmic methodology, new surgical techniques and concepts can be introduced in a stepwise manner to ensure the evidence-based progression of knowledge. © 2019, European Society of Sports Traumatology, Knee Surgery, Arthroscopy (ESSKA).

Journal article (peer-reviewed)abstract
- Purpose: To translate and culturally adapt the Hip Sports Activity Scale (HSAS) to Swedish and validate the Swedish version in patients with femoroacetabular impingement (FAI) syndrome. Materials and Method: The original German version was translated to Swedish. To determine reliability, validity, and floor and ceiling effects, a questionnaire set consisting of the Swedish version of the HSAS, the Copenhagen Hip and Groin Outcome Score (HAGOS), the short version of the international hip outcome tool, and the Tegner Activity Scale was completed pre‐operatively by 30 patients planned for arthroscopic hip surgery for FAI syndrome. To determine responsiveness, pre‐operative and one‐year follow‐up HSAS data from 30 patients treated with arthroscopic hip surgery for FAI syndrome were collected. Results: For test‐retest reliability, the interclass correlation was 0.930. The HSAS correlated to the Tegner score (r = 0.794, P < 0.01), as well as to the HAGOS subscale of “physical activity” (r = 0.436, P < 0.05). Cohen's effect size and the standardized response mean were 0.25 and 0.28, respectively. Ceiling and floor effects were between 7% and 10%. Conclusion: The Swedish version of the HSAS is a reliable and valid measurement to determine sports activity levels in patients with FAI syndrome.
