Abstract:

Total knee arthroplasty (TKA) is widely carried out in clinical practice and can significantly improve the quality of life of patients with end-stage knee joint diseases. With the continuous improvement of the design of artificial knee joint prosthesis and the increase of the elderly population, the number of patients receiving total knee arthroplasty has increased year by year. As one of the postoperative complications of TKA, the incidence of periprosthetic distal femoral fracture (PDFF) has also gradually increased. Most of the PDFF patients are elderly, often accompanied by osteoporosis and various underlying diseases. Compared with conventional fractures, the patient's condition is more complex and difficult to manage. Orthopedic doctors are required to not only develop treatment plans based on the type of fracture, but also comprehensively evaluate the overall condition and consider the reconstruction of joint function. This article reviewed the research status of incidence rate, fracture classification and treatment of PDFF after TKA in recent years.

Key words: Total knee arthroplasty, Periprosthetic fractures, Femoral fracture, Classification, Treatment
