[Mechanics of the knee joint, part II, the final rotation (author's transl)]

Abstract

Mobility of the knee of the horse. The modification of medial and lateral femoral condyles by additional movement of the cruciate ligaments shown on the animal joint. Final rotation in the human knee-joint shapes the femoral condyles by additional movement of the cruciate ligaments. The roll-slide movement and final rotation lead to curving of the medial condyle of the femur in the transverse plane. The transition from the roll-slide into a tilting movement in the final phase of ultimate rotation reduces the power of the posterior ligamentous system of the knee-joint when there is a force tending to hyperextend.
