Joint locking (medicine) symptom of: 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 tibia is being used up by the lateral condyle of femur during extension. Therefore, lateral femoral condyle acted as an axis for medial femoral condyle to rotate backwards. This movement is aided by 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
Triple tibial osteotomy not get crushed. The triple tibial osteotomy was developed by a New Zealand veterinary orthopaedic specialist, Dr. Warrick Bruce, while he was working in Adelaide, South Australia. By changing the geometry of the forces of gravity and muscle contractions that act on the stifle during weight-bearing, it aims to neutralise the shear force that causes the cranial movement of the tibia with respect to the femur. This shear force develops because the canine tibial plateau – the weight-bearing aspect of the joint – is sloped caudally (downwards towards the back of the joint)and there is an acute angle between the
