Purpose: To determine the incidence of lateral meniscus posterior root tears LMPRTs in patients undergoing anterior cruciate ligament ACL reconstruction and identify associated risk factors. Methods: We conducted a retrospective, multicenter study using data from the Francophone Arthroscopic Society's registry.
The study included all the patients in the registry who underwent ACL reconstruction surgery between June and June ; we excluded incomplete data. Variables investigated as potential risk factors for LMPRTs included age, sex, nature of surgery primary or revision , pivot shift test result, side-to-side laxity under anesthesia, presence of ACL remnant, occurrence of medial meniscal tear, and presence of collateral ligament injury.
Risk factors were analyzed using a logistic regression model. Mean age at surgery was Concerning delay to surgery, the mean time was 8.
Age, side-to-side laxity, and collateral ligament injury were not found to be significant risk factors. In multivariate analysis, male sex, revision surgery, pivot shift test result, and a low volume of ACL remnant remained significant. Side-to-side laxity was also a significant factor in multivariate analysis. Level of evidence: Level III, retrospective comparative case series. Published by Elsevier Inc. All rights reserved.
