Knee injuries are extremely common in young athletes, but the question often is how much is this going to affect them in future life. The most obvious long term risk of injury is osteoarthritis, which is a degenerative condition known as "joint wear and tear" which happens to joints. Knee injuries usually occur in contact sports or sports that require lots of jumping and rapid change of direction such as football and basketball. In a recent study carried out on young adults, knee injury increases the risk of future diagnosed knee OA about sixfold with highest risks found after cruciate ligament injury, meniscal tear and intra-articular fracture. Specific exercises like a pistol squat are fantastic for training chain muscle activation to try and reduce the risk of these injuries.
