title: Long-term follow-up of cemented fixed-bearing total knee arthroplasty in a Chinese population: a survival analysis of more than 10 years.
abstract: The aims of this study were to evaluate the long term clinical outcomes and survival rate of total knee arthroplasty (TKA) in Chinese population and the risk factors for failure. Between 1985 to 2001, 297 patients underwent primary TKAs with cemented fixed bearing platform in our center. Survival rate was 92.7% at 10 years, with reoperation of the implant as the endpoint, and 90.4% at 15 years. Main reasons for failure were infection and aseptic loosening. Clinical evaluation of 96 knees with HSS knee score showed the mean scores increased from 56.58 ± 11.05 preoperatively to 92.29 ± 10.95 postoperatively. RA patients had lower long-term survivorship compared with OA patients. Younger patients had better HSS scores. Patella strategy and posterior-cruciate-ligament (PCL) strategy had no effect on implant survivorship and clinical outcome. In conclusion, this was one of first studies showing valid long-term outcomes of primary TKA in Chinese.
