Anatomy, Bony Pelvis and Lower Limb, Knee

The knee is the largest joint in the body (see Image. Lateral View of the Right Knee). The knee is primarily a hinge joint, allowing leg flexion and extension. Other movements are also possible, though to a limited extent. Tibiofemoral and patellofemoral articulations make the knee a compound synovial joint.

The knee is critical to efficient bipedal movements like walking, running, and jumping. Muscular support is this joint's most important stabilizing factor, and proper conditioning and training can help prevent sports injuries. Understanding its structure helps optimize lower limb rehabilitative strategies.
