Unicompartmental knee arthroplasty with a mobile-bearing prosthesis: Long-term results

Abstract

Anteromedial osteoarthritis (OA) of the knee, a distinct pathological condition described by White et al. in 1991 [1], is an ideal indication for unicompartmental knee arthroplasty (UKA). In this condition, the cartilage erosion in the medial compartment begins typically in the anterior half of the tibial plateau, the cartilage being preserved over the posterior third (Fig. 6.1).
