Unicompartmental Knee Arthroplasty

Abstract

Unicompartmental arthroplasty of the knee is a surgical technique for the treatment of arthritis of the medial or lateral tibiofemoral compartment. It involves the replacement of the arthritic compartment with a metal-on-polyethylene articulation. In an appropriately selected patient population, it offers reliable relief of pain and improves function providing an attractive alternative to both total knee arthroplasty and realignment osteotomies.
