About The Knee
The knee is a complex joint that joins the femur (thigh bone) to the tibia (shin bone). The fibula (the other bone in the lower leg) and the patella (knee cap) are the other bones that comprise the knee joint.
In addition to being complex, the joint is the largest in the body. It’s supported by ligaments that stabilize the knee and join the bones and tendons that connect muscles to bones. The knee is a modified hinge joint with a wide range of motion, primarily flexion, and extension. It’s essential to carry the body's weight when walking, running, and jumping.
