  • Title: Cruciate-retaining total knee arthroplasty in patients with at least fifteen degrees of coronal plane deformity.
    Author: Kubiak P, Archibeck MJ, White RE.
    Journal: J Arthroplasty; 2008 Apr; 23(3):366-70. PubMed ID: 18358374.
    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 degrees (> or =10 degrees of varus or > or =20 degrees 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.
