Meniscal Transplants -by Vic Goradia, M.D.

Severe loss of meniscal tissue from previous tears can lead to degeneration of articular cartilage. Articular cartilage is a hard, smooth layer that cushions bones inside of a joint, such as a knee. As this protective layer wears away, arthritis can develop.

Technology developed over the past 20 years allows us to replace your lost meniscus with a new one from a cadaver. The goal is to replace the shock absorbing function of your lost meniscus with a new one, a meniscal transplant, that will help slow the progression of cartilage degeneration and arthritis.

The Donor Meniscus

The meniscus is obtained from companies that harvest organs and tissues from cadavers. The tissue is cleansed, sterilized, tested for infections and/or diseases and frozen. All of this is done to reduce the risk of infection or disease. Knee X-rays and other tests will be performed to determine the best size for your meniscus. It is best to order the tissue several months before the scheduled surgery as it takes time to locate the proper match.

Repair and Recovery

The Meniscal Transplant surgical procedure is performed with arthroscopic assistance. The new meniscus is inserted through a small incision in the front of the knee. The meniscus is then sewn in place with multiple sutures that are tied through another small incision.

For the first two weeks after surgery, a continuous passive motion machine (CPM) will help bend and straighten your knee. For your convenience, this will be sent to your home. During this time you should not place any weight on the affected leg, and you will need to use crutches.

Later in your recovery walking will be permitted with the use of a brace that locks your knee straight. This Meniscal Transplant support is needed for about six weeks.

Physical therapy will start the week after Meniscal Transplant surgery and will continue for two to three months.

When can I return to sports?

This is a frequent question and depends on the person. But usually, strenuous activities and sports may be resumed after six months, with physician approval.
