Anatomy of locking of the knee joint with clinical anatomy
Locking of the knee happens during the last stages of extension when a person is standing up. Medial rotation of femur occurs as the space available at the lateral condyle of the tibia is being used up by the lateral condyle of the femur during extension. Therefore, lateral femoral condyle acts as an axis for medial femoral condyle to rotate backwards. This movement is aided by the oblique pull of the ligaments of the knee joint and contraction of the quadriceps muscles. The ligaments are pulled taut when the knee joint is locked in place during standing. When the knee is flexed, it is unlocked by the popliteus muscle through the lateral rotation of femur
