An overuse injury can occur when you take on too much physical activity too quickly.
In athletes, the most common acute injuries are ACL and MCL sprains. A sprain is the stretching or tearing of a ligament. An ACL injury can occur when an athlete changes direction quickly, stops suddenly, or lands from a jump. MCL injuries often occur in contact sports when the outside of the knee joint is struck.verall, knee injuries make up about 55% of all sports injuries. An injury to the knee can cause an athlete to experience pain in many areas of the knee joint. The knee is formed by the convergence of three bones: the femur (upper leg bone), the tibia (lower leg bone) and the patella (kneecap).
