Purpose: Owing to the aging population, posttotal knee arthroplasty fractures are becoming increasingly frequent. The treatment of these fractures is still very challenging for the surgeons. The present research work assesses the prevalence of femoral periprosthetic fractures along with its treatment options, classification and risk factors.Method: The present study was conducted fromMay 2012 to September 2019 at Orthopedics department first affiliated hospitalXinjiang Medical University. The present study included 21 patients, suffering from periprosthetic kneefractures. There were 10 males and 11 females with mean age of 70.76±8.31years (range, 44 to 80 years). All the patients were treated by revision surgery. Results: The classification was based on Rorabeck system, according to which, 2 cases were Rorabeck 1, 14 cases were Rorabeck 2 and 4 cases were Rorabeck type 3.One patient was classified as Felix type 2.Conclusion:Knee joint revision can achieve good surgical results in the treatment of distal femoral periprosthetic fracture after TKA. Reasonable and correct surgical operation is the key to successful operation. Postoperative follow-up results were good. Keywords: Total knee arthroplasty,Periprosthetic fractures, Revision
