Independent effects of sports activity level and surgical timing on concomitant lesions in anterior cruciate ligament injuries
摘要
To investigate anterior cruciate ligament (ACL) injury associated meniscal and cartilage lesions and to evaluate the independent effects of sports activity level and surgical timing on their distribution.
MethodsA retrospective cohort analysis was conducted on all primary ACL reconstructions performed at a specialized sports medicine hospital between 2018 and 2022. The primary outcome was the prevalence of ACL-associated injuries. Secondary outcomes included classification of associated injuries, differences according to sports activity level, and injury-to-surgery time. Multivariate logistic regression was used as the main analysis.
ResultsA total of 582 patients were included, with a median age of 26.0 years. Of these, 321 (55%) had at least one meniscal tear. Cartilage lesions were identified in 93 patients (16%), most commonly affecting the medial femoral condyle (MFC). Registration in a professional sports club was associated with increased odds of lateral meniscus posterior horn tears. Surgical delay showed increasing odds of chondral lesions, particularly involving the MFC, as well as medial meniscal tears. Surgeries performed more than 30 days after injury were associated with significantly lower odds of identifying ramp lesions.
ConclusionACL injuries are frequently associated with a range of concomitant intra-articular lesions. Medial compartment lesions are primarily associated with surgical timing, independent of sports activity level. In contrast, lateral meniscus posterior horn tears were more common among professional athletes. Surgeries performed within 30 days of injury were associated with higher odds of detecting ramp lesions, regardless of sports activity level.
