A structured evaluation of the symptomatic medial Oxford unicompartmental knee arthroplasty (UKA)

Abstract

Unicompartmental knee arthroplasty (UKA) has several advantages over total knee arthroplasty; however, in many reports, the risk of revision remains higher after UKA. Many reasons for failure of UKA exist. Successful treatment starts with accurate assessment of the symptomatic UKA as a specific mode of failure requires a specific solution. A structured and comprehensive evaluation aids assessment of the symptomatic UKA. This review provides an overview of the causes for a symptomatic medial UKA, its risk factors, diagnostic modalities that can be used, and briefly discusses treatment options.
