ABSTRACT
The meniscotibial ligaments (LMT) of humans are capsular fibers with proximal origin in the lateral border of the menisci and distal insertion in the lateral border of the tibial condyle, also called coronary ligament of the knee. However, few studies describe the presence, course and anatomical variations of this ligament. Our objective was to evaluate the LMT through quantitative and descriptive methods. Eighty-five knees were examined(42 right knees [RK] and 43 left knees [LK]), dissected, evaluated, catalogued and photographed by four examiners. Twenty knees (23.53%) presented LMT, 6 (30%) in RK and 14 (70%) in LK. In two RKs, the LMT presented proximal insertion in the medial menisci and distal insertion in medial tibial condyle; in the other ones, the LMT presented proximal insertion in the lateral menisci and distal insertion in the lateral tibial condyle. In the LK, four LMT presented proximal insertion in the medial menisci and distal insertion in the medial tibial condyle, while the other ones presented proximal insertion in the lateral menisci and distal insertionin the lateral tibial condyle. One LMT in the LK presented proximal and distal insertion in both menisci and tibial condyle. The analysis of human corpses in our study suggests that the presence of the LMT is much more common in the LK than in the RK, with more frequent insertion in the proximal region of the lateral menisci and distal insertion in the lateral tibial condyle.
