Multiple studies have shown that modern unicompartmental knee replacement performs very well in the vast majority of patients who are appropriate candidates.
ADVANTAGES OF PARTIAL KNEE REPLACEMENT OVER TOTAL KNEE REPLACEMENT
- Quicker recovery
- Less pain after surgery
- Less blood loss
Also, because the bone, cartilage, and ligaments in the healthy parts of the knee are kept, most patients report that a unicompartmental knee replacement feels more “natural” than a total knee replacement. A unicompartmental knee may also bend better.
DISADVANTAGES OF PARTIAL KNEE REPLACEMENT
The disadvantages of partial knee replacement compared with total knee replacement include slightly less predictable pain relief and the potential need for more surgery. For example, a total knee replacement may be necessary in the future if arthritis develops in the parts of the knee that have not been replaced.
In a partial knee replacement, only the damaged compartment is replaced with an artificial device.
