Partial Knee Replacement, One Side of the Joint

Rhode Island rates for HCPCS 27446

Replacement of the worn surfaces on only one side of the knee: the damaged bone ends there are resurfaced with metal and plastic parts, while the healthy remainder of the joint and its ligaments are left alone. It suits arthritis confined to one part of the knee. Recovery is generally quicker and the knee feels more natural than after a full replacement, but more of the original joint remains that could wear out later.
