Arthroscopic meniscus repair is an outpatient surgical procedure to repair torn knee cartilage. The torn meniscus is repaired by a variety of minimally invasive techniques and requires postoperative protection to allow healing. Physical therapy is useful to regain full function of the knee, which occurs on average 4-5 months after surgery.

The goal of meniscus surgery is to preserve healthy meniscus tissue. A meniscus tear requires a blood supply to heal. Only the outer third portion of the meniscus has blood supply to enable healing of a tear. Repairs are generally limited to this peripheral region of the meniscus.
