Because so many activities place extreme stress on the knee, it is one of the most traumatized joints in the physically active population. The knee is commonly considered a hinge joint because its two principal movements are flexion and extension. However, because rotation of the tibia is an essential component of knee movement, the knee is not a true hinge joint. The stability of the knee joint depends primarily on the ligaments, the joint capsule, and the muscles that surround the joint. The knee is designed primarily to provide stability in weight bearing and mobility in locomotion; however, it is especially unstable laterally and medially.
Muscles and ligaments provide the main source of stability in the knee.
The knee joint complex consists of the femur, the tibia, the fibula, and the patella (Figure 20–1). The distal end of the femur expands and forms the convex lateral and medial condyles, which are designed to articulate with the tibia and the patella. The articular surface of the medial condyle is longer from front to back than is the surface of the ...
