Final answer:
An ACL tear increases the risk of osteoarthritis due to joint instability and cartilage wear. Factors such as age, joint injury, and excess body weight also contribute to OA risk. Protective measures can help mitigate this risk.
Step-by-step explanation:
Once an athlete suffers an ACL tear, their risk of developing osteoarthritis (OA) increases. The ACL, or anterior cruciate ligament, is crucial for stabilizing the knee, and when injured, it can lead to joint instability. Factors such as age, joint injury, congenital malformations, or excess body weight contribute to the risk of OA. Athletes, particularly those involved in high-impact sports, are at a heightened risk due to increased chances of joint injury. Protective measures and proactive joint care can mitigate some risk, but if the cartilage wears away, it can result in pain, disability, and a heightened risk of OA.
OA occurs when the protective cartilage on the ends of your bones wears down over time, and it can be exacerbated by injuries like ACL tears. Treatment focuses on relieving symptoms and improving joint function, but currently, there is no cure for OA. Maintaining a healthy weight, avoiding overuse of the joint through repetitive movements, and protecting knees from injuries can help in the prevention of OA.
