    • 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.

  • Derotation brace and knee function in patients with anterior cruciate ligament tears
  • 1985
  • Ingår i: Arthroscopy. - 0749-8063 .- 1526-3231. ; 1:4, s. 264-267
  • Tidskriftsartikel (refereegranskat)abstract
    • In this article we have tested a ready-made brace to evaluate whether it could improve function in the anterior cruciate ligament injured patient. All patients had their full extent of injury mapped out at arthroscopy. We believe that arthroscopy before treatment for a torn anterior cruciate ligament injury is necessary in order to treat meniscus lesions that could interfere with the rehabilitation. In this study, 26 patients were unstable with a positive pivot-shift, and 16 patients were operated on and thus stable. All patients performed a performance test with and without the brace in a randomized order. Before the start of the investigation, we postulated that patients with a quadriceps atrophy who were unstable would improve their function with the derotation brace. We could not find any effects of the brace in this study. The brace did not significantly improve function in the group of patients who were unstable with a quadriceps atrophy. On the other hand, the brace did not impair function in the patients. We conclude that to be able to improve knee function in the unstable knee, other modes of treatment than bracing are necessary. Bracing should be seen as a complement to these other treatments.

  • Arthroscopic Partial and Total Meniscectomy : A Long-term Follow-up Study With Matched Controls
  • 2002
  • Ingår i: Arthroscopy. - 0749-8063 .- 1526-3231. ; 18:2, s. 183-189
  • Tidskriftsartikel (refereegranskat)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
  • Ingår i: Arthroscopy. - : W B SAUNDERS CO-ELSEVIER INC. - 0749-8063 .- 1526-3231. ; 32:8, s. 1631-
  • Tidskriftsartikel (refereegranskat)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.

  • Patients With Concomitant Intra-articular Lesions at Index Surgery Deteriorate in Their Knee Injury and Osteoarthritis Outcome Score in the Long Term More Than Patients With Isolated Anterior Cruciate Ligament Rupture: A Study From the Swedish National Anterior Cruciate Ligament Register
  • 2018
  • Ingår i: Arthroscopy. - : W B SAUNDERS CO-ELSEVIER INC. - 0749-8063 .- 1526-3231. ; 34:5, s. 1520-1529
  • Tidskriftsartikel (refereegranskat)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.

  • Spectroscopic Measurement of Cartilage Thickness in Arthroscopy: Ex Vivo Validation in Human Knee Condyles
  • 2012
  • Ingår i: Arthroscopy. - : WB Saunders. - 0749-8063 .- 1526-3231. ; 28:10, s. 1513-1523
  • Tidskriftsartikel (refereegranskat)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.

    • © 2017 Arthroscopy Association of North America Purpose To radiographically assess the tibial tunnel up to 5 years after anterior cruciate ligament (ACL) reconstruction using hamstring tendon autografts and biocomposite interference screws. Methods Fifty-one patients underwent anatomic single-bundle ACL reconstruction with metal interference screws in the femur and biocomposite interference screws in the tibia. Standardized digital radiographs with weight-bearing anteroposterior and lateral views of the index knee were taken in the early postoperative period and at 2 and 5 years postoperatively. Of 51 patients, 40 (78%) underwent radiographic assessment on all 3 occasions. Subjective and objective clinical assessments were obtained preoperatively and at the 5-year follow-up. Results The mean follow-up period was 65 months (±3.9 months), with a minimum of 59 months. The width of the tibial tunnel on the anteroposterior view was 9.4 mm (±1.4 mm) in the early postoperative period and 9.2 mm (±1.5 mm) at 5 years (P =.64). The corresponding widths on the lateral view were 9.6 mm (±1.5 mm) in the early postoperative pe riod and 9.0 mm (±1.4 mm) at 5 years (P =.014). In 33 of 40 patients (83%) the width of the tibial tunnel had decreased on 1 or both views at 5 years compared with the early postoperative period. The study group had improved significantly at the 5-year follow-up compared with the preoperative assessments in terms of the KT-1000 arthrometer laxity tests (MEDmetric, San Diego, CA), pivot-shift test, Tegner activity scale, and Lysholm knee score (P < .001). No correlations were found between the tunnel widths and the KT-1000 assessment. Conclusions In 83% of patients, the width of the tibial tunnel had decreased on 1 or both radiographic views at 5 years compared with the early postoperative period after ACL reconstruction using biocomposite interference screws. Level of Evidence Level II, prospective study.
