ABSTRACT
Purpose@#Many studies have been conducted on the cause of the medial meniscus posterior horn root (MMPHR) tears. A previous study reported that the relatively large size of the medial femoral condyle (MFC) compared to the size of the medial tibial condyle (MTC) could cause a tear of the MMPHR. The authors conducted a study to confirm that this was correct. @*Materials and Methods@#Patients who underwent magnetic resonance imaging of the knee at our Hospital from March 2011 to April 2019 were divided into a group with a tear of MMPHR and a control group without a tear. The size (MFC, MTC) and relative size ratio of the MFC and the MTC (MFC/MTC) were measured and compared to determine if there was any correlation with the tear of MMPHR. @*Results@#The mean MFC size of the 175 patients with MMPHR tear was 24.6±2.1 mm (0°), 23.5±2.1 mm (30°), 24.1±2.2 mm (60°), and the mean MTC size was 28.2±2.2 mm. The mean size of the MFC of the 147 control subjects was 25.2±2.4 mm (0°), 23.9±2.3 mm (30°), and 24.5±2.6 mm (60°), and the mean size of the MTC was 29.0±2.6 mm. The mean ratios (MFC/MTC) of the 175 patients with MMPHR tears were 0.87±0.05 (0°), 0.83±0.04 (30°), and 0.85±0.05 (60°) for each location. The corresponding mean ratios (MFC/MTC) of the 147 control subjects were 0.87±0.05 (0°), 0.83±0.04 (30°), and 0.85±0.05 (60°). There was no significant difference between the patient group and the control group. @*Conclusion@#The size and relative ratio of MFC and MTC do not appear to be related to a tear of the MMPHR.
