**4.3 Comparsion of angular changes in knee joint in transversal plane**

As a result of the disease external rotation is marked on the operated side during the initial contact and loading response periods and throughout the swing phase. After the treatment, on the other hand, the crus undergoes external rotation throughout the stance phase and the internal rotation is insufficient at the swing phase.

Distinct external rotation appeared on the unoperated side throughout the gait cycle, crus rotation occurred after the procedure towards proper internal rotation (Fig. 5).

Ext – external rotation, Int – internal rotation
