Satisfaction and survival rates after total knee arthroplasty were high according to literatures. However, around 8% of revision surgeries were still noted and almost half of them were early failures, which were most seen in 2 years after primary surgery. This study aimed to find out the factors lead to early failures after total knee arthroplasty. Data were collected based on the National Health Insurance Research Data Base of Taiwan from 1996 to 2010. Primary total knee arthroplasty surgeries were included. Revisional total knee arthroplasty, removal of total knee implant and arthrotomy surgeries registered after primary total knee surgeries are seen as failures.Introduction
