Total knee replacement surgery is considered one of the most effective treatment options for sever osteoarthritis, reducing pain and disability.

Knee Replacement Surgery Options

Depending on the patient’s knee condition, there are various types of procedures that could best treat it. Using minimally-invasive techniques (that reduce scarring and minimize recovery times) and non-reactive prosthetics (never metal-on-metal replacements, which are known to cause defects), Mount Sinai orthopaedic surgeons are skilled in performing the following procedures.

Arthroscopy of the Knee

This minimally-invasive procedure involves threading a camera through a small incision into the knee joint. Surgeons then use the camera to guide other instruments to the problem area in order to repair damage ranging from arthritis deterioration to meniscus tears.

Osteotomy of the Knee

This procedure involves removing or adding a small section of bone to either the upper shinbone or lower thigh bone in order to help decrease pressure on the damaged section of the knee joint. It is generally performed on patients thought to be too young for a total joint replacement.

Total Knee Replacement

This inpatient procedure removes the diseased or injured cartilage and bone from the kneecap, thigh bone, and shinbone, and replaces it with an artificial joint. The surgery can be performed using minimally-invasive techniques, which reduce blood loss and scarring and minimize recovery times.

Partial (Unicondylar) Knee Replacement

This procedure replaces only the damaged bone and cartilage in the knee with an artificial prosthesis, leaving the healthy tissue unmodified.

Patello-femoral Replacement

For patients who have severe arthritis of the knee cap, without involvement of the remainder of the knee, this procedure inserts a patella (kneecap) replacement without disturbing the rest of the knee joint.
