Quadriceps muscle weakness after anterior cruciate ligament reconstruction: A risk factor for knee osteoarthritis?

摘要: Objective To identify risk factors for knee osteoarthritis (OA) 10–15 years after anterior cruciate ligament (ACL) reconstruction. We hypothesized that quadriceps muscle weakness ACL reconstruction would be a factor radiographic and symptomatic OA later. Methods Subjects with (n = 258) were followed years. Subjects unilateral injury at the 10–15-year followup included in present study. Outcomes Cincinnati score, joint laxity, hop performance, isokinetic strength tests 6 months, 1 year, 2 postoperatively. At followup, radiographs taken graded according to Kellgren/Lawrence classification (range 0–4). Results Of 212 subjects (82%) assessed 164 had injury. The mean ± SD age was 27.4 8.5 Increased (odds ratio [OR] 1.06, 95% confidence interval [95% CI] 1.01–1.11) meniscal and/or chondral lesion (OR 2.05, CI 1.00–4.20) showed significantly higher odds OA. Low self-reported function postoperatively 0.95, 0.92–0.98) loss of between 2-year 1.00, 1.00–1.01) Quadriceps not associated OA. Conclusion This study detected no association as measured later.
