Trauma is the leading cause of knee injury. Falls, twisting injuries and collisions during sports cause damage to the bones, joint cartilage, muscles, tendons and ligaments of the knee.
Repetitive use is a common cause of knee injuries. People whose occupations require a large amount of kneeling, climbing, squatting or stooping are particularly susceptible to the development of knee pain. Athletes who play sports that require sudden changes of direction or jumping are at increased risk of knee injuries.
Over time, our bodies age. Inflammation from “wear and tear” of the joints results in arthritis. The meniscus is susceptible to degeneration over time, resulting in pain caused by small tears. Chronic inflammation of the tendons may predispose them to rupture.
