title: Tibiofemoral movement 4: changes of axial tibial rotation caused by forced rotation at the weight-bearing knee studied by RSA.
abstract: We studied the knees of 11 volunteers using RSA during a step-up exercise requiring extension while weight-bearing from 50 degrees to 0 degrees. The findings on weight-bearing flexion with and without external rotation of the tibia based on MRI were confirmed.
