Arthroscopic Meniscal Repair

Arthroscopic Meniscal Repair

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.  

Symptoms of Torn Meniscus

Torn knee cartilage generally produces pain in the region of the tear and swelling in the knee joint. These symptoms are made worse with pivoting motions, squatting, and vigorous activities. Torn meniscus fragments can get caught in the knee joint and cause catching sensations. If a large enough fragment becomes lodged between the bearing surfaces, the knee may ‘lock’ and become unable to be fully bent or extended.

Who should consider arthroscopic meniscus repair?

  • the patient is healthy and wishes to remain active,
  • the patient understands the rehabilitation, and accepts the risks of surgery,
  • the meniscus tear is located in the periphery of the meniscus,
  • the meniscus tissue is of good quality, and
  • the surgeon is experienced in meniscus repair
