Overview
The need for ACL reconstruction surgery depends on the symptoms of ACL tear and the extent of the injury.
An anterior cruciate ligament or ACL may be partially or completely torn. A partial ACL tear may heal with physical therapy, home treatment, rest, and anti-inflammatory medications without having surgery.
A completely torn ACL does not heal on its own and you may experience knee instability, pain, and swelling. Conservative treatments may not be able to completely heal the ACL injury. Returning to work and activities without an intact ACL increases the chances of tearing the meniscus. A torn meniscus further increases the risk of developing osteoarthritis in the future.
