Knee Conditions and Injuries

The knee joint is the largest and most complex joint in the body. This major weight bearing joint requires three bones, twelve muscles, four ligaments, two major tendons, articular cartilage, and two menisci to function properly. The knee is a hinge joint that connects the thigh bone (femur) with the shin bone (tibia), and allows your lower leg to sling easily forward and backward as you walk, run, kick, and jump. Because so many activities place extreme stress on the knee, it is one of the most commonly injured joints in the body.
