Abstract
BACKGROUND: The purpose of this study is to report the long-term outcomes and survivorship of a high flexion knee system. METHODS: We identified 1312 patients (1664 knees) who underwent primary total knee arthroplasty with the Vanguard Complete Knee System with 10-year minimum follow-up. Preoperative and postoperative range of motion, Knee Society scores, complications, and reoperations were evaluated. RESULTS: At an average of 11.9 years of follow-up, 88 knees were revised (5.3%). The deep infection rate was 1.4%. There was an average range of motion improvement of 3.9°, pain level decreased by 35.8, Knee Society clinical scores improved by 48, and Knee Society functional scores improved by 15.1 (all P < .001). Survival was 96.4% at 10 years for aseptic causes and 95.5% for all causes. CONCLUSION: At a 10-year minimum follow-up, this high flexion knee system demonstrates excellent survivorship.
