Uni-compartmental Knee Replacement

Patients requiring knee replacement occasionally have osteoarthritis entirely localised to one or other knuckle or compartment of the knee, sometimes associated with very mild bow leg or knock knee deformity. In some of these patients, and providing that strict criteria are adhered to, a partial knee replacement, more usually called a uni-compartmental knee replacement may be performed.

Partial knee replacement has several advantages over total type knee replacement. The surgery preserves more of the patient’s own natural knee. Recovery is faster and the replaced knee feels more natural and more supple following surgery. The principle disadvantage is that partial knee replacements appear to be less durable than total knee replacement, most National Registries reporting failure rates at ten years around double those associated with conventional total knee replacement.
