Unicompartmental Knee Arthroplasty

by Craig J. Della Valle, MD; Richard A. Berger, MD; Aaron G. Rosenberg, MD

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.
