Abstract
PURPOSE: The purpose of this study was to evaluate the use of total knee arthroplasty (TKA) using a computer-assisted navigation system for treating osteoarthritis with extra-articular deformity. METHODS: Between January 2006 and January 2009, computer-assisted navigation TKAs were performed on eight knees in eight patients, who had severe osteoarthritis with an ipsilateral extra-articular deformity. All patients were followed up for a minimum of 24 months. The involved knees were evaluated by function scores, Knee Society knee scores, and analyzing knee flexion before the operation and at the latest follow-up. RESULTS: Postoperatively, the function scores, Knee Society knee scores, and knee flexion all improved significantly. The ideal mechanical axis of the lower extremity was obtained in all cases. CONCLUSION: TKA using a computer-assisted navigation system might provide an efficient treatment for patients with osteoarthritis in combination with an extra-articular deformity.
