An ACL tear is usually caused by a sudden change in direction, rapid deceleration, landing awkwardly from a jump, or a direct blow to the knee. These movements can overstretch or tear the ligament.
Treatment options depend on the severity of the tear and the patient’s activity level. Non-surgical treatments include rest, ice, compression, elevation (RICE), physical therapy, and bracing. Surgical options, typically recommended for athletes or those with significant instability, involve reconstructing the ACL using a graft.
