Independent effects of sports activity level and surgical timing on concomitant lesions in anterior cruciate ligament injuries.
Article in International orthopaedics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo 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.
