Windswept deformities – An indication to individualise valgus correction angle during total knee arthroplasty

Abstract

PurposeWe aimed to determine variation in femoral valgus correction angle (VCA) between the two limbs in a patient with windswept deformity undergoing total knee arthroplasty (TKA). MethodsFemoral VCA was measured on full-length, hip-to-ankle, standing radiographs and was compared between the varus and the valgus limbs in 66 patients with windswept deformities. ResultsThe mean VCA in varus knees was significantly higher compared to mean VCA in valgus knees (p=0.002). ConclusionSignificant difference in VCA is present between the varus and the valgus limbs in most patients with windswept deformity undergoing TKA.
