At a glance
Research suggests the risk of a second ACL injury, either to the same or the opposite knee, is meaningfully elevated compared with individuals without a prior tear, which is part of why structured return-to-sport testing is emphasized.

ACL · What graft options are used for ACL reconstruction?
Common graft choices include the patient's own patellar tendon, hamstring tendon, or quadriceps tendon, or occasionally donor tissue, each with different considerations regarding strength, donor-site symptoms, and recovery.
ACL · What is the risk of re-tearing the ACL?
Research suggests the risk of a second ACL injury, either to the same or the opposite knee, is meaningfully elevated compared with individuals without a prior tear, which is part of why structured return-to-sport testing is emphasized.
ACL · Can the ACL heal on its own without surgery?
The ACL has limited capacity for biological healing compared with some other ligaments, so a torn ACL generally does not reliably heal back to its original structure without surgical repair, even though functional stability can sometimes be regained through rehabilitation alone.
ACL · The anterior cruciate ligament runs diagonally from the back of
The anterior cruciate ligament runs diagonally from the back of the thigh bone to the front of the shin bone, crossing the posterior cruciate ligament in an X-shape at the center of the knee joint, which gives the pair their name.
