Q. Regarding the movements at the knee joint: (Solved)
1. popliteus ‘unlocks’ the extended knee by producing medial rotation of the femur
2. there is no active rotation of the extended knee
3. passive extension of the knee does not result in ‘locking’ of the joint
4. the posterior cruciate ligament prevents backward displacement of the femur on the tibial plateau
5. the major role of the menisci is in flexion/extension of the knee
- b. there is no active rotation of the extended knee
