The aim of this study was to investigate the usefulness of computer\u2010assisted surgery\u2013total knee arthroplasty (CAS\u2010TKA) under this circumstance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We retrospectively analyzed patients with osteoarthritic knee and marked coronal femoral bowing who underwent TKA at our institution. The CAS\u2010TKA and the conventional techniques were compared by radiographic parameters in coronal and sagittal planes, and rotational alignment of femoral component was assessed by computed tomography (CT) scans. The Hospital for Special Surgery (HSS) and International Knee Society (IKS) scores were obtained for all patients preoperatively and at the last follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 65\u00a0knees were enrolled in this study. Twenty\u2010eight TKAs implanted using a CT\u2010free navigation system, and the remaining 37 TKAs implanted using the conventional technique. CAS\u2010TKAs were more consistent than conventional TKAs in aiding proper postoperative MA and ideal alignments of femoral component in the coronal and sagittal planes. However, CAS\u2010TKA group was not obtained at significantly higher rates of femoral component in axial plane. At a mean follow\u2010up of 43\u00a0months, there was no significant difference in HSS and IKS scores between the groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Although CAS\u2010TKA did not have superior functional outcomes in the short\u2010term follow\u2010up, proper coronal and sagittal alignment of femoral component and postoperative MA were obtained in patients with marked coronal femoral bowing.
