Document Summary

The knee joint is composed of three joints, which are the femoropatellar and the lateral and medial tibiofemoral joints. The femoropatellar joint acts as a plane joint, while the tibiofemoral joints act as hinge joints, resulting in flexion, extension, and slight rotation. The overall joint locks in place by rotating medially. The knee joint is laterally and medially reinforced by semilunar cartilages, known as menisci. These three ligaments are continuous with the tendon of the quadriceps muscle of the anterior thigh. The joint is associated with many bursae, one of which is the subcutaneous prepatellar bursa, which is often injured when the knee is bumped anteriorly. The intracapsular ligaments are crossed over each other, forming an x. The cruciate ligaments are named for their tibial positions, and they lie outside the synovial cavity. The elbow joint is a hinge joint, formed by the articulation of the trochlea of the humerus with the trochlear notch on the ulna.
