Patients who have experienced anterior cruciate ligament (ACL) injuries may be at an increased risk of developing posttraumatic osteoarthritis, according to an article published in The Conversation. Experts noted that although these injuries are more common among athletes, ACL injuries can also occur in nonsporting situations such as colliding with objects, falling, landing after a jump, or slowing down after running. Previous studies have shown that 12% and 50% of patients who have undergone reconstructive procedures following an ACL injury may develop posttraumatic osteoarthritis within 5 and 10 to 17 years, respectively. The experts suggested that individuals who have experienced ACL injuries watch for symptoms of osteoarthritis—including joint pain, stiffness, swelling, crunching, or clicking, as well as a loss of functionality. Recent research has demonstrated that exercise regimens involving plyometric training, strengthening movements, and agility drills may reduce the risk of sports- and contact-related ACL injuries by about 53% to 67%. For those who have already experienced ACL injuries or have been diagnosed with posttraumatic osteoarthritis, maintaining an active lifestyle, exercising regularly, and managing body weight may prevent further knee injuries and improve disease severity.
