The meniscus is the small shock-absorbing pad that protects the articular cartilage and assists in joint stabilization. Meniscus injuries can cause symptoms such as locking, catching, pain, and swelling. Treatment depends on symptoms and the location of the tear.

Preserving the Meniscus:

The first goal of treatment is to keep the normal tissue structure of the meniscus. In the case of meniscal tears, the first line treatment is an attempt at repair.

Historically, in the days of open meniscus surgery, the entire meniscus was removed. Unfortunately, long term follow up studies of these patients have found that many go on to develop degenerative arthritis.

With the arrival of arthroscopy it is now standard treatment to remove only the damaged area. Today, cartilage surgeons recognize the protective value of the meniscal cartilage and make every effort to preserve this valuable tissue.

Repairing the Meniscus:

To continue the meniscal function after a tear, surgeons may repair the meniscus using a variety of techniques. Repair is performed arthroscopically using special sutures or absorbable implants to secure the tear. Only tears located on the outside edge of the meniscus, where there is a good blood supply for healing, are appropriate for these repairs.

Even with the newest techniques available, certain tears are not repairable due to the location and pattern of the tear. A partial meniscectomy with removal of only the torn cartilage is then performed. The remainder of the meniscus is preserved to maintain its function.
