Meniscal TransplantsSevere 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 that will help slow the progression of cartilage degeneration and arthritis. The goal of Meniscal Transplant The Donor MeniscusThe meniscus is obtained from companies that harvest organs and tissues from cadavers. The tissue is cleansed, sterilized, tested for infections/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 RecoveryThe 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 house. 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 support is needed for about six weeks. Physical therapy will start the week after surgery and will continue for two to three months. Strenuous activities and sports may be resumed after six months, with physician approval. |
