What is a meniscus?
It is a c-shaped wedge of tough, rubbery cartilage in the knee about the size of a silver dollar. There are two menisci (plural of meniscus), one on each side of the knee joint. They act as shock absorbers, protecting the joint surface from daily wear and reducing friction between the thigh bone and shin bone. They also help stabilize the knee by controlling its rotation.

How is the meniscus injured?
Any sudden twisting of the knee can tear the cartilage, causing pain, swelling and a catching sensation. A bucket-handle tear, named for the shape of the tear, is a typical injury caused when the foot is planted in one direction and the knee twists in the other direction.

What has been the treatment for torn meniscus?
Until about 15 years ago, standard treatment was to remove the entire cartilage wedge. Doctors now know that without the protection of the meniscus, the surface of the knee joint degenerates rapidly. The result is painful, disabling “wear and tear” arthritis (also called Osteoarthritis) within 10-15 years for most people. Because of these facts, surgeons at The Florida Knee and Orthopedic Centers have repaired torn cartilage or removed only the torn portion since 1985. The decision to repair or remove cartilage depends on the location and severity of the tear. If the meniscus cannot be repaired or has been previously removed, a remarkable new procedure called a meniscus transplant can offer a positive solution.

What is a meniscus transplant?
The latest advances in medical science have made it possible to transplant donor cartilage into your knee. In keeping with their consistent leadership in knee care, surgeons at The Florida Knee and Orthopedic Centers have done more meniscus transplants than any other surgeons nationwide.
The cartilage transplant is an hour-long, outpatient, arthroscopic procedure. A regional anesthesia is used, and you will go home the same day.
You will wear an immobilizer to keep your leg straight during four weeks of physical therapy. Many patients may return to their active lifestyles, including sports, within 12-16 weeks.
The procedure is performed at the center’s Clearwater office or the outpatient department at Palms of Pasadena Hospital, a modern 310-bed facility located in St. Petersburg in Florida’s Tampa Bay area. Since its opening in 1963, Palms has gained national distinction by having recognized Centers of Excellence including a nationally renowned orthopedic surgery program.

Why should I have a meniscus transplant?
It may slow the onset of painful, disabling arthritis and avoid or delay the need for knee replacement at a very early age. A transplant can allow you to continue working and enjoying your favorite sports or fitness activities. Anyone under age 50 who has had 50% or more of the meniscus removed is a candidate for a transplant. Also, anyone with a recent tear that cannot be repaired should consider a transplant.

Where will I have incisions?
You will have only a one inch incision on the front of your knee, plus three nicks in the skin so small that a suture is not needed.

When can I return to work?
The time varies with the activities your job requires, ranging from seven days for desk jobs to 12-16 weeks for heavy labor.

Contact any Florida Knee and Orthopedic Center to schedule an x-ray and examination by one of our surgeons. In most cases, the surgeon will tell you at your first visit if you are a potential candidate for meniscus transplant. If you are not local to the Tampa Bay area, you can mail us your latest and greatest x-rays and the “op report” of your cartilage surgery. Our surgeons will review the information and we will email or telephone a response.
