Unicompartmental knee arthroplasty

This review on the use of unicompartmental knee arthroplasty (UKA) examines the history of UKA development, considers indications and compares fixed and mobile bearing designs. Advantages of the use of UKA in anteromedial knee osteoarthritis compared to the use of TKA are addressed, followed by a formal review of the literature concerning survival analyses in both designer and non-designer series as well as registry data. The expanding role and future for partial knee arthroplasty is discussed.
