1.Introduction
Oxford unicompartmental knee replacement (UKR) has become an alternative procedure for osteoarthritis of the knee with excellent long-term results [1,2]. UKR is a safe procedure, and low perioperative complication rates have been reported in the literature [3]. The most common complications are aseptic loosening, polyethylene dislocations, unexplained pain, and periprosthetic tibial fractures [2,4] The prevalence of supracondylar fractures after total knee replacement (TKR) is reported to be 0.5%-2% [5,6]. Although few case reports have been published on condylar fractures, to our knowledge, periprosthetic supracondylar femoral fracture after UKR has not been reported in the literature [7,8,9].
In this case report, we present a patient with a postoperative supracondylar femoral fracture who had been previously treated for ipsilateral condylar periprostatic femur fracture after UKR. We aimed to discuss the mechanism of the fracture, treatment strategies, and its impact on patient’s clinical outcome.
