The negative values for the tibia indicate that the tibia was narrower than the femur in the coronal plane. Data are the mean, and data in parenthesis are standard deviation
AP anterior-posterior, dLA distance from lateral femoral articular edge to lateral tibial articular edge, dLC distance from lateral femoral condyle to lateral tibial condyle, dMA distance from medial femoral articular edge to medial tibial articular edge, dMC distance from medial femoral condyle to medial tibial condyle
^aThe medial femoral condyle was medial to the medial tibial condyle
^bThe lateral femoral condyle was lateral to the lateral tibial condyle
