The knee joint is the largest synovial joint in the body. It consists of:
1. the articulation between the femur and tibia
2. the articulation between the patella and the femur
External ligaments:
The main ligaments are-
1. collateral ligaments
2. cruciate ligaments
3. popliteal ligaments
4. patellar ligament
Movements:
Possible movements at knee joint are flexion, extension, lateral rotation and medial
rotation.
