dc.description.abstractBackground: We report 15-year survival, clinical and radiographic follow-up data for the Press Fit Condylar Sigma total knee replacement (PFC Sigma TKR). Methods: Between October 1998 and October 1999, 235 consecutive TKRs were performed in 203 patients. Patients were reviewed at a specialist nurse-led clinic prior to surgery, and at five, eight-to-ten and 15 years postoperatively. Clinical outcomes, including Knee Society Score (KSS), were recorded prospectively at each clinic visit, and radiographs were obtained. Results: Of our initial cohort, 99 patients (118 knees) were alive at 15 years, and 31 patients (34 knees) were lost to follow-up. 13 knees (5.5%) were revised; five (2.1%) for infection, seven (3%) for instability and one (0.4%) for aseptic loosening. Cumulative survival with the end-point of revision for any reason was 92.3% at 15 years, and with revision for aseptic failure as the end-point was 94.4%. The mean KSS knee score was 77.4 (33 to 99) at 15 years, compared with 31.7 (2 to 62) preoperatively. Of 71 surviving knees for which X-rays were available, 12 (16.9%) had radiolucent lines and one (1.4%) demonstrated clear radiographic evidence of loosening. Conclusion: The PFC Sigma TKR represents a durable, effective option for patients undergoing knee arthroplasty, with excellent survival and good clinical and radiographic outcomes at 15 years.
