Partial Knee Replacement

The knee is generally divided into three compartments: medial (inside), lateral (outside), and patellofemoral (the joint between the kneecap and the thighbone). Most patients with disease such as arthritis that is severe enough to consider knee replacement surgery have damage to two or more of these compartments and a total knee replacement would be the better treatment option.

Partial Knee Replacement, or Unicompartmental arthroplasty (UKA), is an option for a minority of patients who have wear confined primarily to one compartment and may be candidates for a partial knee replacement.
