Popliteus muscle assists in flexing the leg upon the thigh; when the leg is flexed, it will rotate the tibia inward. It is especially called into action at the beginning of the act of bending the knee, inasmuch as it produces the slight inward rotation of the tibia, which is essential in the early stage of this movement. When the knee is in full extension, the femur slightly medially rotates on the tibia to lock the knee joint in place. Popliteus is often referred to as the "Key" to unlocking the knee since it begins knee flexion by laterally rotating the femur
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
