The knee is composed of three separate compartments. Osteoarthritis sometimes develops in only one compartment of the knee, while the other two compartments remain relatively healthy. Patients who have osteoarthritis in only one compartment may be candidates for partial knee replacement.
The advantage of a partial knee is that it resurfaces only the damaged cartilage of the knee, preserving the undamaged cartilage. The benefits of this procedure include a smaller incision (3,4 inches), a quicker recovery, and less bone removal. The disadvantages are that partial knee surgery may not last as long as total joint replacement surgery. You and Dr. Roberts will determine if a partial knee is appropriate for you.
