Valgus Deformity Correction in Total Knee Replacement: An Overview

Abstract

The correction of deformities in valgus knee is a challenge to perform a total knee arthroplasty (TKA) for a surgeon. Approximately 10% of patients who sustain a TKA have a valgus deformity. The bone and soft tissue deformities complicate the restoration of proper alignment, positioning of components and achievement of joint stability. In the valgus knee are often present lateral femoral and tibial deficiencies, contracted lateral and elongated medial soft tissues and multiplanar deformities. Different classifications have been reported to guide surgical management and various surgical strategies have been described with variable clinical results. In relation to the severity of the deformity, different implant designs may be used. The important factors to obtain stability and longevity of TKA for good functional outcome are restoration of neutral mechanical axis and correct ligament balance.
