What is the definition or description of: acl reconstruction?

ACL reconstruction: Acl reconstruction consisted of replacing the acl with a graft either for your own body or donor tendon. It is usually done arthroscopically. Tunnels are drilled in the thigh (femur) bone and lower leg (tibia) bone and placing the graft in the tunnels and fixating them with various methods. The techniques and grafts vary and it depends on the your age and surgeon experience.

Replacement: Because an acl (anterior cruciate ligament) cannot heal itself on its own, an acl is "reconstructed" by placing a graft tendon substitute (from your own or donor cadaver tendon) placed into tunnels made in the original acl position, and fixed in place with screws, buttons, or other fixation device. The body then replaces the cells and structure of the graft over 6-8 months, recreating a new acl.
