Beyond valgus stress radiography: arithmetic HKA angle (aHKA) as a superior predictor of limb alignment after UKA

Abstract Purpose Accurate prediction of postoperative coronal alignment is essential for successful outcomes following medial unicompartmental knee arthroplasty (UKA). Traditionally, valgus stress femorotibial angle (FTA) has been used to estimate the correctability of varus deformity; however, its...
