Long-Term Effects of an Untreated ACL TearAn untreated Anterior Cruciate Ligament (ACL) tear can lead to significant long-term consequences affecting knee stability and overall mobility. Often resulting from sports injuries, an ACL tear may cause chronic knee instability, elevate the risk of meniscus tears, cartilage damage, and osteoarthritis.

Often resulting from sports injuries, an ACL tear may cause chronic knee instability, elevate the risk of meniscus tears, cartilage damage, and osteoarthritis. Early diagnosis through physical examination and imaging is crucial to mitigate these risks. Treatment options range from surgical intervention to strengthen the ligament to non-surgical methods that focus on muscle strengthening around the knee. Recovery times vary, with surgical approaches requiring up to a year of rehabilitation and non-surgical methods focusing on lifestyle modifications. Preventive measures include strengthening exercises, proper sports techniques, and immediate medical evaluation after knee injuries. Understanding the implications of an untreated ACL injury is vital for maintaining an active lifestyle and preventing further knee deterioration.
