Consequences of not getting acl surgery to fix and previous injury?

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"

Reinjury.: If you choose to live with a torn ACL,you are putting your knee at risk for "giving out", which can cause more permanent damage to the knee, such as loss of cartilage, which could lead to arthritis.
