I have a torn anterior cruciate ligament injury on my left knee which happened last year, can I get a surgery now to repair my leg?

Yes. Yes, you can still have an acl reconstruction. Acl tears do not heal on their own & having it replaced can help you maintain a healthy/ active lifestyle in the years to come. The acl is a major knee stabalizer, and can provide security to your knee that may prevent further damage to nearby tendons, ligaments, muscles, articular cartilage, meniscus, & bones when compared to a "loose knee" .
