  1. MCT = medial compartment in the proximal tibia, WB = weight-bearing, Δ difference = difference in each parameter between non-WB and WB conditions, tibial position = the relative angle of WB line to x–axis in the tibial coordinate system, femoral position = the relative angle of WB line to a surgical epicondylar axis, 95%CI = 95% confidence interval; *Significant difference = p < 0.01
