Abstract:
PURPOSE: Authors intend to evaluate the mid-term clinical, radiographic results and patient's satisfaction degree for hybrid total knee replacement arthroplasties (TKRA) retrospectively. MATERIALS AND METHODS: Sixty-one knees in 39 patients were followed retrospectively for at least 5 years at a mean 6.5 (5.1-9.1) years. The average age of the patients at the time of operation was 55 (29-70) years. RESULTS: The average 26.4 preoperative knee rating score and 22.5 function score were improved to average 91 and 85.9 respectively at the last follow-up. The average range of motion was increased to 100.1 preoperatively to 121.2 at the final follow-up. Roentgenographic evaluation revealed a radiolucency rate of 82% of patients at tibia and femur interface, but no radiolucent line was detected on patellar component. All of patients were satisfactory for their postoperative status subjectively. CONCLUSION: The mid-term results of hybrid TKRA was reliably good with increased range of motion, restoration of function, rare complication and patient's own satisfaction. But authors considered that more long-term follow-up evaluation must be needed because of the high rate of radiolucency.
