Cruciate-Retaining Total Knee Arthroplasty in Patients with at Least Fifteen Degrees of Coronal Plane Deformity☆
Abstract
There has been debate regarding the superiority of posterior stabilized (PS) or cruciate-retaining knee designs in total knee arthroplasty (TKA). The proponents of PS TKA argue that a relative contraindication to the use of cruciate-retaining total knee arthroplasty is that of significant coronal plane deformity. The purpose of this study is to compare our minimum 10-year results of posterior cruciate ligament–retaining TKAs in patients with preoperative coronal plane deformity of at least 15° (≥10° of varus or ≥20° of valgus) to historical results of PS TKA designs in similar patients. We found, at a minimum 10-year follow-up, very good results with a 93% (95% confidence interval, 87%-98%) revision-free survivorship at 10 years and no revisions for instability or loosening.
