From 90º to 150º of knee flexion (upright kneeling to full flexion), there is an average femoral posterior translation of 36 mm. During this movement, there is also 8º of external rotation, accompanied by lower values of abduction and lateral translation.

At full flexion, the femoral condyles rest on the posterior rim of the tibial plateau and external rotation allows for the alignment of the popliteal fossa with the posterior margin of the medial tibial plateau.
