Symptoms and Signs of Knee Injury

Doctor's Notes on Knee Injury

A knee injury involves trauma and damage to any of the structures of the knee joint, including bones, ligaments, or cartilage as well as injury to the surrounding muscles, tendons, and skin. Normal wear and tear on the joint that occurs with aging can cause knee injuries. Other causes include sports injuries, falls, and other accidents.

Symptoms and signs of a knee injury depend on the severity of the injury and the particular structures that are damaged. Symptoms can include mild to severe knee pain and swelling, immobility or limited range of motion of the joint, bruising, redness, warmth, and damage to the overlying skin. Other associated signs and symptoms can include pain in the legs, gait disturbances, pain with exercise or with specific movements, and instability of the knee joint.
