The following parameters were assessed using MRI: the lateral femoral condyle and medial femoral condyle height and depth ratio (LFC-H\/D, MFC-H\/D), notch width index, intercondylar notch angle, the lateral tibial plateau slope, and medial tibial plateau slope (MTPS), and medial tibial depth. Values were compared between these 2 groups using the independent\n                      <jats:italic>t<\/jats:italic>\n                      test and the Mann-Whitney\n                      <jats:italic>U<\/jats:italic>\n                      test. Univariate logistic regression analysis was subsequently performed to identify independent risk factors.

In sex-specific analyses, both male and female patients with isolated PCL rupture had a significantly lower LFC-H\/D (female patients: 0.46 vs 0.52;\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001; male patients: 0.51 vs 0.52;\n                      <jats:italic>P<\/jats:italic>\n                      = .035).
