- A better understanding of patient characteristics and the way common concomitant injuries affect the recovery of muscle function after surgery should help providers to treat patients with anterior cruciate ligament (ACL) injuries. The aim of this study was to determine whether patient characteristics, concomitant injuries and graft choice at ACL reconstruction were associated with symmetrical knee muscle function at one year. The hypothesis was that the presence of concomitant injuries would negatively influence the opportunity to achieve symmetrical knee function at the one-year follow-up.Data was extracted from the Swedish National Knee Ligament Register and a rehabilitation outcome register between August 2012 and December 2016. The patients had been evaluated with a battery of tests comprising knee extension and flexion strength, vertical jump, hop for distance and the side-hop test one year after ACL reconstruction. Univariable and multivariable logistic regression analyses were performed with achieving a limb symmetry index (LSI) of ≥90% in all tests of muscle function as primary outcome.A total of 263 patients with a mean age of 26.7±10.3years were included in the study (47% females). No patient demographic or intra-operative predictors were found to be significant when attempting to predict the achievement of a symmetrical muscle function. Lateral meniscus injury and a patellar tendon autograft reduced the odds of achieving an LSI of ≥90% in knee extension strength, OR=0.49 [(95% CI 0.25-0.97), p=0.039] and OR=0.30 [(95% CI 0.14-0.67), p=0.0033] respectively. In addition, reduced odds of recovering knee extension strength were found in older patients, OR=0.76 [(95% CI 0.60-0.98), p=0.034]. A higher pre-injury level of physical activity increased the odds of recovering knee flexion strength, OR=1.14 [(95% CI 1.01-1.29), p=0.037].Intra-operatively identified concomitant injuries or graft choice did not affect the likelihood of recovering symmetrical performance in five different tests of muscle function one year after ACL reconstruction. However, fewer than one in four patients achieved an LSI of ≥90% in all tests.Prospective observational study: Level 2.

- There is an increasing demand to quantify the footprints, ecological, economic and social, in terms of the effect of different interventions in healthcare. The aim of this study was to compare two systems providing patients with diabetes with insoles in terms of their eco-logical, economic and social footprints. Prefabricated insoles (PRI) were compared with custom-made insoles (CMI). Using a welfare-economic monetary approach, costs were estimated for (1) treatment, (2) travelling to and from the hospital in terms of both fuel and time consumed by the patients and (3) society through emissions contributing to climate change. The proportion of patients/year that could be supplied within the same budget, for each individual treatment, was calculated. The cost of the insoles was 825 SEK (PRI) and 1450 SEK (CMI), respectively. The cost, mean value/patient due to the consumption of patients’ time at the department, was 754 SEK (PRI) and 1508 SEK (CMI), respectively. Emissions, in terms of CO2 equivalent, were 13.7 (PRI) and 27.4 (CMI), respectively. Using PRI, a total of 928 patients could be provided/year compared with 500 patients if CMI are used. By using PRI, the cost/treatment was reduced by 46%. The cost of treatment dominated and the cost of time consumed by patients were also substantial. The societal cost of contributing to climate change was of low importance. By using PRI, the needs of 86% more patients could be met within the same budget. Using these methods, the contri-bution of healthcare systems to the 17 Sustainable Development Goals approved by the UN can be quantified.

- Purpose: To investigate how range of motion of the hips and the lumbar spine are affected by continued elite, alpine skiing in young subjects, with and without a magnetic resonance imaging verified cam morphology, in a 2-year follow-up study. The hypothesis is that skiers with cam morphology will show a decrease in hip joint range of motion as compared with skiers without cam, after a 2-year follow-up. Method: Thirty adolescent elite alpine skiers were examined at the baseline (mean age 17.3 ± 0.7 years) and after 2 years. All skiers were examined for the presence of cam morphology (α-angle > 55°) using magnetic resonance imaging at the baseline. Clinical examinations of range of motion in standing lumbar flexion and extension, supine hip flexion, internal rotation, FABER test and sitting internal rotation and external rotation were performed both at the baseline and after 2 years. Results: Skiers with and without cam morphology showed a significant decrease from baseline to follow-up in both hips for supine internal rotation (right: mean − 13.3° and − 10.9° [P < 0.001]; left: mean − 7.6° [P = 0.004] and − 7.9° [P = 0.02]), sitting internal rotation (right: mean − 9.6° and − 6.3° [P < 0.001]; left: mean − 7.6° [P = 0.02] and − 3.3° [P = 0.008]) and sitting external rotation (right: mean − 16.9° and − 11.4° and left: mean − 17.9° and − 14.5° [P < 0.001]) and were shown to have an increased left hip flexion (mean + 8.4° and + 4.6° [P = 0.004]). Skiers with cam were also shown to have an increased right hip flexion (mean + 6.4° [P = 0.037]). Differences were found between cam and no-cam skiers from baseline to follow-up in the sitting internal rotation in both hips (right: mean 3.25°, left: mean 4.27° [P < 0.001]), the right hip flexion (mean 6.02° [P = 0.045]) and lumbar flexion (mean − 1.21°, [P = 0.009]). Conclusion: Young, elite alpine skiers with cam morphology decreased their internal rotation in sitting position as compared with skiers without the cam morphology after 2 years of continued elite skiing. Level of evidence: II.

- BackgroundThere is conflicting evidence regarding the association between cam morphological changes and hip pain, and it remains unclear who with cam morphology will develop hip pain and who will not. This study aimed to investigate the correlation between cam morphology, hip pain, and activity level at a 5-year follow-up in young Alpine and Mogul skiers.MethodAll students (n = 76) at angstrom re Ski National Sports High School were invited and accepted participation in this prospective study at baseline. Magnetic resonance imaging (MRI) of both hips was conducted to evaluate the presence of cam morphology (alpha -angle >= 55 degrees) and its size alongside the reporting of hip pain, type, and frequency of training by the Back and hip questionnaire, at baseline. After 5 years, the skiers were invited to complete a shortened version of the same questionnaire.ResultsA total of 60 skiers (80%) completed the follow-up questionnaire, of which 53 had concomitant MRI data. Cam morphology was present in 25 skiers (47.2%, 39 hips). Hip pain at baseline and at follow-up was reported in 17 (28.3%) and 22 (36.7%) skiers, respectively. No correlations were found between the activity level, the frequency, and the size of cam morphology and hip pain, except for the right hip alpha -angle at 1 o'clock and hip pain in skiers with cam morphology at baseline (r(s) = 0.49; P = 0.03) and at follow-up (r(s) = 0.47; P = 0.04). A total of 73.3% skiers had retired, of which 48% reported this was due to injuries.ConclusionHip pain was not shown to be correlated, or had a low correlation, with activity level and the presence and size of cam morphology in young skiers on a 5-year follow-up. Based on these results, cam morphology or activity level did not affect hip pain to develop during 5 years of follow-up in young skiers. Furthermore, this study highlights that almost 75% of young elite skiers had retired from their elite career with almost 50% reporting that this was due to injuries sustained from skiing.

- 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.

- 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).

Tidskriftsartikel (refereegranskat)abstract
- Background: Radiologically verified cam-type femoroacetabular impingement (FAI) has been shown to correlate with reduced internal rotation, reduced passive hip flexion, and a positive anterior impingement test. Purpose: To validate how a clinical examination of the hip joint correlates with magnetic resonance imaging (MRI)-verified cam deformity in adolescents. Methods: The sample group consisted of 102 adolescents with the mean age 17.7 +/- 1.4 years. The hip joints were examined using MRI for measurements of the presence of cam (alpha-angle >55) and clinically for range of motion (ROM) in both supine and sitting positions. The participants were divided into a cam and a noncam group based on the results of the MRI examination. Passive hip flexion, internal rotation, anterior impingement, and the FABER (flexion, abduction, and external rotation) test were used to test both hips in the supine position. With the participant sitting, the internal/external rotation of the hip joint was measured in 3 different positions of the pelvis (neutral, maximum anteversion, and retroversion) and lumbar spine (neutral, maximum extension, and flexion). Results: Differences were found between the cam and noncam groups in terms of the anterior impingement test (right, P = .010; left, P = .006), passive supine hip flexion (right: mean, 5; cam, 117; noncam, 122 [P = .05]; and left: mean, 8.5; cam, 116; noncam, 124.5 [P = .001]), supine internal rotation (right: mean, 4.9; cam, 24; noncam, 29 [P = .022]; and left: mean, 4.8; cam, 26; noncam, 31 [P = .028]), sitting internal rotation with the pelvis and lumbar spine in neutral (right: mean, 7.95; cam, 29; noncam, 37 [P = .001]; and left: mean, 6.5; cam, 31.5; noncam, 38 [P = .006]), maximum anteversion of the pelvis and extension of the lumbar spine (right: mean, 5.2; cam, 20; noncam, 25 [P = .004]; and left: mean, 5.85; cam, 20.5; noncam, 26.4 [P = .004]), and maximum retroversion of the pelvis and flexion of the spine (right: mean, 8.4; cam, 32.5; noncam, 41 [P = .001]; and left: mean, 6.2; cam, 36; noncam, 42.3 [P = .012]). The cam group had reduced ROM compared with the noncam group in all clinical ROM measures. Conclusion: The presence of cam deformity on MRI correlates with reduced internal rotation in the supine and sitting positions, passive supine hip flexion, and the impingement test in adolescents.

- BACKGROUND:The aim of the study was to compare the results after arthroscopic anterior cruciate ligament (ACL) reconstruction using either the double-bundle or single-bundle technique with hamstring tendon autografts in an unselected group of patients. HYPOTHESIS:Double-bundle ACL reconstruction will render a better outcome on the pivot-shift test. STUDY DESIGN:Randomized controlled trial; Level of evidence, 1. METHODS:A randomized series of 103 patients (33 women, 70 men; median age, 27 years; range, 18-52 years) with a unilateral ACL rupture underwent anatomic ACL reconstruction. The double-bundle technique was used in 53 patients, and the single-bundle technique was used in 50 patients. The ACL footprint was visualized, and the femoral tunnel was drilled through the anteromedial portal; interference screw fixation was used at both ends. The patients were examined preoperatively and at a median of 26 months (range, 22-42 months) after the reconstruction by a blinded observer. The primary variable was the pivot-shift test. RESULTS:At 2-year follow-up, 98 patients (93%) were examined. Clinical assessments at follow-up revealed no significant differences between the double-bundle and single-bundle groups in terms of the pivot-shift test, KT-1000 arthrometer laxity measurements, manual Lachman test, range of motion, Lysholm knee scoring scale, Tegner activity scale, Knee Injury and Osteoarthritis and Outcome Score (KOOS), 1-legged hop test, and square hop test. A significant improvement was seen in both groups compared with the preoperative values in terms of most clinical assessments. CONCLUSION:In this prospective randomized study, the primary variable, the pivot-shift test, and other subjective and objective outcome variables revealed no significant differences between the double-bundle and single-bundle techniques at 2 years after ACL reconstruction in an unselected group of patients.
