Knee stability is important to protect the articular and meniscal cartilage from injury. Patients who tear their anterior cruciate ligament (ACL) are at risk for further damage to these structures if they desire to continue in activities such as running, jumping, and pivoting on the knee.

For this reason, it is recommended that patients undergo arthroscopic-assisted reconstruction of this ligament to protect the knee. ACL reconstruction may be performed in conjunction with the cartilage restoration procedures in those patients with combined injury.
