WebIn open chain movement (when the foot is NOT fixated to the ground) the tibia internally rotates in relation to the femur. In closed chain (foot IS fixated to the ground) the tibia externally rotates until the knee hits terminal knee extension which tightens the cruciate ligaments maximizing knee stability. WebSep 13, 2024 · Mechanism: External rotation of tibia with reference to the femur or Internal rotation of femur with reference to the tibia (relative external rotation of tibia) tightens the cruciate ligaments and the joint is locked. The medial femoral and tibial condyle are larger in AP direction (ovoid) compared to their lateral counterparts.
