Tóm tắt

Purpose. To present midterm results of Duracon total knee arthroplasty (TKA) performed between 1991 and 2001. Methods. One man and 43 women (65 knees) aged 46 to 84 (mean, 63) years who underwent primary TKAs using the Duracon prosthesis performed by a single surgeon were followed up for a mean of 8.5 (range, 5–11) years. All TKAs were cruciate-retaining and cemented, with only 9 of the patellae resurfaced. The diagnosis was osteoarthritis in 42 patients (61 knees), and rheumatoid arthritis in 2 patients (4 knees). Patients were assessed using the Knee Society Clinical Rating System, the Oxford Knee Score, and the Knee Society Total Knee Arthroplasty Roentgenographic Evaluation and Scoring System. Results. The mean Knee Society knee score was 86 (range, 43–100) and the function score was 68 (0–100). 94% of patients reported no or only mild pain. The mean Oxford Knee Score was 19. There was no patellofemoral complication, deep vein thrombosis or pulmonary embolism. Complications included a superficial infection and an uncontrolled deep infection. One patient had the insert exchanged for wear at the 11-year follow-up, and another had the polyethylene insert and tibial tray revised after a motorcycle accident. Conclusion. The Duracon TKA had good midterm clinical results with absence of patellofemoral complications.
