Overview

ACL reconstruction is surgery to replace a torn anterior cruciate (KROO-she-ate) ligament (ACL) — a major ligament in your knee. ACL injuries most commonly occur during sports that involve sudden stops and changes in direction — such as soccer, football, basketball and volleyball.

Ligaments are strong bands of tissue that attach one bone to another bone. During ACL reconstruction, the torn ligament is removed and replaced with a band of tissue that usually connects muscle to bone (tendon). The graft tendon is taken from another part of your knee or from a deceased donor.

ACL reconstruction is an outpatient surgery that's performed by a doctor who specializes in surgical procedures of the bones and joints (orthopedic surgeon).
