Incidence and risk factors for medial meniscus lesions at the time of ACL reconstruction: An analysis of 4697 knees - 27/11/23
Incidence et facteurs de risque des lésions du ménisque médial au moment de la reconstruction du LCA: analyse de 4697 genoux
Résumé |
Introduction |
Medial meniscus lesions (MMLs) are a common finding at the time of anterior cruciate ligament (ACL) reconstruction. Posteromedial compartment evaluation reduces the rate of missed diagnoses. The aim of this study was to determine the incidence of MMLs in patients undergoing ACLR, when using posteromedial compartment evaluation.
Material and method |
A retrospective analysis of prospectively collected data was performed. All patients who underwent primary ACLR between January 2013 to March 2023 were considered for study eligibility. The epidemiology was defined by categorizing and reporting the incidence and spectrum of tear types. Risk factors associated with MM lesion were analyzed using a logistic regression model.
Results |
MMLs were identified in 1851 (39.4%) of 4697 consecutive patients undergoing ACLR. The overall incidence of MMLs was 33.1% for the period of 0-3 months, 38.7% at 3-12 months and 59.6% at >12 months. The incidence increased with longer durations of time between injury and surgery due to significant increases in complex, bucket handle, ramp and flap lesions. The largest increase in incidence was observed for complex tear patterns. Risk factors associated with MMLs included time between injury and surgery >3 months (OR 1.320; 95% CI, 1.155–1.509; p<0001) and >12 months (OR 3.052; 95% CI, 2.553–3.649; p<0001), male sex (OR 1.501; 95% CI, 1.304–1.729; p<0.0001), BMI≥25 (OR 1.193; 95% CI, 1.046–1.362; p=.0088) and LM lesion (OR 1.737; 95% CI, 1.519–1.986; p<0001).
Conclusions |
Overall, MMLs were identified in 39.4% of 4697 patients undergoing ACL reconstruction when posteromedial compartment evaluation was performed in addition to standard anterior viewing. The incidence of MMLs and their complexity increased significantly with increasing time intervals between the index injury and ACL reconstruction. Risk factors for the presence of medial meniscus tear included male gender, BMI and LM lesions.
