- The purpose of the study was to evaluate the clinical effect of ketoprofen after arthroscopic subacromial decompression (ASD). The design was randomized, prospective, and double-blind, with a placebo control group. Forty-one consecutive patients with subacromial impingement syndrome, were randomized to treatment with ketoprofen 200 mg once daily or placebo for 6 weeks following ASD. For additional analgesia, patients used paracetamol if necessary. Clinical follow-up was performed at 6 weeks and at 2 years postoperatively. At the 6-week follow-up, the patients treated with ketoprofen had a statistically significant increase in UCLA total score (P < .05), range of movement (P < .05), and satisfaction (P < .05), and they had significantly less pain (P < .05). There was no statistical difference between the ketoprofen and placebo groups regarding strength. Patients receiving ketoprofen had significantly less need for additional analgesia (P < .05). At the 2-year follow-up, there were no differences in the scores between the ketoprofen and placebo group.

Arthroscopic Partial and Total Meniscectomy : A Long-term Follow-up Study With Matched Controls
- 2002
-
In: Arthroscopy. - : Elsevier BV. - 0749-8063 .- 1526-3231. ; 18:2, s. 183-189
-
Journal article (peer-reviewed)abstract
- Purpose: The purpose of this study was to compare the clinical and radiographic outcome of arthroscopic partial and total meniscectomy.Type of Study: Retrospective outcome study.Methods: Thirty-six male patients with stable knees, no previous knee injury, and arthroscopic meniscectomy were matched into 2 groups: partial or total. In addition, a group of individuals with no known history of knee injury was matched to each patient with meniscectomy. All patients were re-examined by a clinical and radiographic examination 14 years after surgery.Results: At follow-up, radiographic changes, including Fairbank changes and joint space narrowing, were seen in 6 of 18 patients (33%) after partial meniscectomy and in 13 of 18 patients (72%) after total meniscectomy (P < .05). Joint space narrowing >50% of the joint space was seen in 1 patient after partial meniscectomy but was present in 7 patients after total meniscectomy. In the healthy controls, 4 of 36 patients (11%) had radiographic changes but none had joint space narrowing. Fourteen years after surgery almost 70% of patients had a Lysholm score >94 (i.e., normal). Only 5 of 36 patients (14%) in the total meniscectomy group had knee symptoms during activities of daily living. A similar decline in activity levels according to Tegner was seen over time in the control group and in the 2 meniscectomy groups. Conclusions: The frequency of radiographic changes 14 years after meniscectomy is related to the size of the meniscus removed, but the grades of these changes are low and have little influence on activity and knee function.

Satisfaction With Knee Function After Primary Anterior Cruciate Ligament Reconstruction Is Associated With Self-Efficacy, Quality of Life, and Returning to the Preinjury Physical Activity
- 2016
-
In: Arthroscopy. - : Elsevier BV. - 0749-8063 .- 1526-3231. ; 32:8, s. 1631-
-
Journal article (peer-reviewed)abstract
- Purpose: To assess whether patient-reported outcomes (psychological factors, appraisals of knee function, and physical activity participation) were associated with satisfaction with knee function after anterior cruciate ligament (ACL) reconstruction. Methods: Participants who were aged 18 to 45 years and a minimum 12 months post primary ACL reconstruction completed a questionnaire battery evaluating knee self-efficacy, knee-related quality of life, self-reported function, and physical activity participation. Participants' responses to the question "If you were to spend the rest of your life with your knee just the way it has been in the last week, would you feel.... (7-point ordinal scale; 1 = happy, 7 = unhappy)" were categorized as satisfied, mostly satisfied, or dissatisfied and used as the primary outcome. Ordinal regression was used to examine associations between independent variables and the primary outcome. Results: A total of 177 participants were included at an average of 3 years after primary ACL reconstruction. At follow-up, 44% reported they would be satisfied, 28% mostly satisfied, and 28% dissatisfied with the outcome of ACL reconstruction. There were significant differences in psychological responses and appraisal of knee function between the 3 groups (P = .001), and significantly more people in the satisfied group had returned to their preinjury activity (58%) than in the mostly satisfied (28%) and dissatisfied (26%) groups (P = .001). Multivariable analysis demonstrated that the odds of being satisfied increased by a factor of 3 with higher self-efficacy, greater knee-related quality of life, and returning to the preinjury activity. Conclusions: People who had returned to their preinjury physical activity and who reported higher knee-related self-efficacy and quality of life were more likely to be satisfied with the outcome of ACL reconstruction.

Journal article (peer-reviewed)abstract
- Purpose: To analyze and compare clinical outcomes after anterior cruciate ligament (ACL) reconstruction 5 and 10 years postsurgery between patients with concomitant intra-articular injuries and those with isolated ACL injury at reconstruction. Methods: Registrations were made using a web-based protocol by physicians for baseline and surgical data. Patients registered their Knee Injury and Osteoarthritis Outcome Score (KOOS) preoperatively and at 5 and 10 years postsurgery. The exclusion criteria for the present study were revisions of previously unregistered ACL surgeries, non-ACL surgeries, patients for whom 10-year follow-up data had not yet been collected, and the proportion of index surgeries that were revision or contralateral interventions. Results: There were 1,295 KOOS scores available for patients 5 years postsurgery, and 1,023 10 years postsurgery from a baseline of 2,751 index reconstructions. A deterioration between the 5-and 10-year scores was observed for patients with concomitant meniscus injury on the KOOS subscales for pain (P = .015), symptoms (P = .005), sport and recreation (P = .011), and knee-related quality of life (QoL) (P = .03) compared with patients with isolated ACL injury. Correspondingly, KOOS subscale score deterioration was seen for combined concomitant cartilage and meniscus injuries for pain (P = .005), symptoms (P = .009), sport and recreation (P = .006), and QoL (P amp;lt; .001). The largest deteriorations were found in sport and recreation (-5.9 points; confidence interval [CI] -10.1, -1.1) and QoL (-6.5 points; CI -10.3, -2.8) subscale scores for patients with concomitant meniscal and cartilage injuries. A similar pattern was not seen between patients with concomitant cartilage injury and isolated ACL injury. Conclusions: The present study reveals that concomitant meniscus injuries at the index operation, either in isolation or in combination with cartilage lesions, render a deterioration of scores on the KOOS outcome subscales for pain, sport and recreation, and quality of life between 5-and 10-year postsurgery follow-up of ACL-reconstructed patients. No such deterioration was seen for patients who had isolated ACL injury.

-
In: Arthroscopy. - : W B SAUNDERS CO-ELSEVIER INC. - 0749-8063 .- 1526-3231. ; 40:1, s. 103-110
-
Journal article (peer-reviewed)abstract
- Purpose: To assess the prevalence of and factors associated with medial collateral ligament (MCL) complex injuries on magnetic resonance imaging (MRI) in patients with anterior cruciate ligament (ACL) tears.Methods: Data were extracted from the Natural Corollaries and Recovery After ACL Injury (NACOX) multicenter longitudinal cohort study. Between May 2016 and October 2018, patients who presented to 1 of 7 health care clinics across Sweden with an ACL tear sustained no more than 6 weeks earlier and who were aged between 15 and 40 years at the time of injury were invited to participate. All the patients included in this study underwent MRI. The mean time from injury to MRI was 19.6 +/- 15.2 days. An orthopaedic surgeon specializing in knee surgery and a musculoskeletal radiologist reviewed all MRI scans. Injuries to the superficial MCL (sMCL), deep MCL (dMCL), and posterior oblique ligament were identified. Stepwise forward multiple binary logistic regression analyses were used to evaluate patient characteristics (age, sex, body mass index, preinjury Tegner activity level, and activity at injury) and injuries on MRI (lateral meniscus [LM] injury, medial meniscus [MM] injury, pivot shift-type bone bruising, medial femoral condyle [MFC] bone bruising, and lateral femoral condyle [LFC] impaction) associated with the presence of MCL complex tears.Results: In total, 254 patients (48.4% male patients) with a mean age of 25.4 +/- 7.1 years were included. The overall prevalence of MCL (sMCL and dMCL) injuries and isolated dMCL injuries was 16.5% (42 of 254) and 24.8% (63 of 254), respectively. No isolated sMCL injuries were found. Posterior oblique ligament injuries were found in 12 patients (4.7%) with MCL (sMCL and dMCL) injuries. An LM injury (odds ratio [OR], 3.94; 95% confidence interval [CI], 1.73-8.94; P = .001) and LFC impaction (OR, 2.37; 95% CI, 1.11-5.07; P = .02) increased the odds of having an MCL injury, whereas an MM injury (OR, 0.26; 95% CI, 0.12-0.59; P = .001) reduced the odds. Isolated dMCL injuries were significantly associated with MFC bone bruising (OR, 4.21; 95% CI, 1.92-9.25; P < .001) and LFC impaction (OR, 3.86; 95% CI, 1.99-7.49; P < .001).Conclusions: The overall combined prevalence of MCL (sMCL and dMCL) injuries and isolated dMCL injuries in patients with ACL tears was high (16.5% + 24.8% = 41.3%). The presence of an LM injury and LFC impaction increased the odds of having an MCL injury, whereas the presence of an MM injury reduced the odds. MFC bone bruising and LFC impaction were associated with the presence of isolated dMCL injuries.Level of Evidence: Level III, retrospective cohort study.

Spectroscopic Measurement of Cartilage Thickness in Arthroscopy: Ex Vivo Validation in Human Knee Condyles
- 2012
-
In: Arthroscopy. - : WB Saunders. - 0749-8063 .- 1526-3231. ; 28:10, s. 1513-1523

Journal article (peer-reviewed)abstract
- Purpose: To evaluate the accuracy of articular cartilage thickness measurement when implementing a new technology based on spectroscopic measurement into an arthroscopic camera. Methods: Cartilage thickness was studied by ex vivo arthroscopy at a number of sites (N = 113) in human knee joint osteoarthritic femoral condyles and tibial plateaus, removed from 7 patients undergoing total knee replacement. The arthroscopic image spectral data at each site were used to estimate cartilage thickness. Arthroscopically derived thickness values were compared with reference cartilage thickness as measured by 3 different methods: needle penetration, spiral computed tomography scanning, and geometric measurement after sample slicing. Results: The lowest mean error (0.28 to 0.30 mm) in the regression between arthroscopic and reference cartilage thickness was seen for reference cartilage thickness less than 1.5 mm. Corresponding values for cartilage thickness less than 2.0 and 2.5 mm were 0.32 to 0.40 mm and 0.37 to 0.47 mm, respectively. Cartilage thickness images-created by pixel-by-pixel regression model calculations applied to the arthroscopic images-were derived to demonstrate the clinical use of a camera implementation. Conclusions: On the basis of this investigation on osteoarthritic material, when one is implementing the spectroscopic method for estimating cartilage thickness into an arthroscopic camera, errors in the range of 0.28 to 0.30 mm are expected. This implementation does not, however, influence the fact that the spectral method performs less well in the cartilage thickness region from 1.5 to 2.5 mm and cannot assess cartilage thicker than 2.5 mm. Clinical Relevance: Imaging cartilage thickness directly in the arthroscopic camera video stream could serve as an interesting image tool for in vivo cartilage quality assessment, in connection with cartilage diagnosis, repair, and follow-up.

Intraoperative measurements of the subacromial distance
- 2002
-
In: Arthroscopy : the journal of arthroscopic & related surgery. - : Elsevier BV. - 0749-8063. ; 18:4, s. 347-352
-
Journal article (peer-reviewed)abstract
- Purpose: The purpose of this study was 2-fold: to document the accuracy of a new measuring device and to intraoperatively compare the subacromial distance between controls and patients with impingement syndrome before and after arthroscopic subacromial decompression (ASD). Type of Study: Clinical study. Methods: When performing an ASD, it is important that bone resection is adequate. Today the correct subacromial distance after bone resection is only assessed by eye, directly or indirectly. The subacromial distance was measured between the anterolateral corner of the acromion and the supraspinatus tendon in the lateral decubitus position. The device was inserted 2 to 3 cm below the anterolateral acromion. There was no subacromial pathology among the controls (n = 15, mean age, 28 years). In 30 patients with impingement syndrome (average age, 53 years) an ASD was performed. The subacromial distance was measured after bursectomy and then after bone resection. Intraindividual and interindividual assessment was performed. Results: The mean value of the subacromial distance in controls was 16 mm, the 95% confidence limits between 14 and 18 mm. The mean value in the group of patients with impingement syndrome was 8 mm before and 16 mm after the decompression. Due to the pressure within the subacromial space, the subacromial distance increased 1 mm. Intraindividual measurements never varied more than 1 mm (n = 5). The correlation coefficient between the measurements by both authors was 0.99. Conclusions: In this study, we assessed and described the use of a measuring device that enables the surgeon to quantify the subacromial distance before and after bone resection. After bone resection, the mean value of the subacromial distance was well within the control values. The amount of bone resected varied from 5 to 13 mm. This new device enables documentation in clinical work as well as in research.
