Document Summary

Knee complex includes the knee joint: capsule, sunvovial membrane, bursae, ligaments, menisci, stability, locking/unlocking mechanism, petallofemoral joint and tibiofibular joint as well. Is both compound and complex (3 or more articular surfaces and meniscus: compound joint = 3+ bones i. e. patella, tibia and femur (tibiofemoral and patellofemoral joints, complex joint = 2+ bones and a meniscus. Permits flexion/extension and some degree of rotation (locking motion) Most stable in extension with support from ligaments.
