Can Partial Knee Replacement Help With Arthritis?
Yes — it is the definitive surgical treatment for single-compartment osteoarthritis.
Osteoarthritis in the knee occurs when cartilage wears away, allowing bone to rub on bone. Partial knee replacement directly resurfaces the worn bone with metal and a polyethylene insert, removing the source of pain.
It is the most effective treatment available for single-compartment osteoarthritis once non-surgical care has been exhausted. Pain relief is dramatic and durable: published series report 90%+ pain relief at 10 years.
Inflammatory arthritis (rheumatoid, psoriatic) usually affects multiple compartments and is better treated with a total knee replacement, although exceptions exist when disease is well-controlled and confined to one compartment.
