Purpose: Arthritic knees with genu valgus deformity present with soft tissue and osseous anomalies that make Total Knee Arthroplasty (TKA) difficult. We retrospectively investigate whether advanced valgus deformity would benefit from Computer-Aided Surgery-TKA (CAS-TKA).
Materials and methods: From January 2003 to September 2011, twenty-six patients having osteoarthritis with valgus deformity in the mechanical axis more than 10 degrees who underwent CAS-TKA were entered into this retrospective study. The usefulness of CAS-TKA was analyzed by the accuracy of placement of the components and postoperative alignment determined using radiographic parameters and Computed Tomography (CT). The Hospital for Special Surgery (HSS) and International Knee Society (IKS) functional scores were obtained for all patients preoperatively and p.. View More»
