Like all joints, your knees are part of your skeletal system. Your knees also contain cartilage, muscles, ligaments and nerves. Your knees help support your weight and let your legs bend and move. Almost any movement that uses your legs relies on your knees — your knees help when you’re walking, running and jumping.
Ligaments are bands of tough, elastic connective tissue that surround a joint to give support. They also limit the joint's movement. The knee joint may become unstable when ligaments are damaged. Ligament damage often happens from a sports injury. A torn ligament severely limits correct knee movement.
