Summary:Background Varus deformity is common in osteoarthritic knee. The purpose of this study was to investigate the clinical and radiographic outcomes after cruciate-retaining (CR) total knee arthroplasty (TKA) for severely varus osteoarthritic knees and compare them to those of mildly to moderately deformed osteoarthritic knees. Methods Eight hundred ninety-four subjects were undergone CR TKA, 137 had severe varus deformity (group 1), and 757 had mild-to-moderate deformity (group 2) of the lower limb preoperatively. Pre- and postoperative outcomes were compared between two groups clinically and radiographically. Results Mean follow-up period was 54.7 ± 28.9 months. Mean age was 77.8 ± 6.7 years in group 1 and 74.5 ± 7.4 years in group 2 ( p
