Knee Joint

The **knee joint** is the largest joint in the body and consists of three articulations. The femoropatellar joint is found between the patella and the distal femur, and the medial and lateral tibiofemoral joints are formed between the corresponding condyles of the femur and tibia. All three articulations are enclosed within a single articular capsule. Functioning primarily as a hinge joint, the knee allows for flexion and extension of the leg, which is achieved through a combination of rolling and gliding motions of the femur on the tibia. While the knee is in a flexed position, it also permits some rotational movement of the leg, although this rotation is restricted when the knee is fully extended. The knee joint is structurally well-suited for weight-bearing when extended; however, it is susceptible to injury from hyperextension, twisting motions or impacts to the medial or lateral sides, especially under load-bearing conditions. *LICENSES AND ATTRIBUTIONS CC licensed content, Shared previously Chapter 9.
