Zhou J, et al. - The experts recruited the 26 patients with infected hip arthroplasty and a radiographically well-fixed, cementless cup or stem in order to ascertain whether infected hip arthroplasty could be treated without removal of a well-fixed cup or stem, which is regarded as the gold standard treatment for infected hip arthroplasty (to remove and re-implant the corresponding whole set of implant components before and after infection control). During the first surgical stage, the stem or cup was preserved and the re-implantation surgery was conducted after the control of infection. From 2008 to December 2016, partial component-retained two-stage reconstruction was performed on 26 patients. With a mean follow-up time of 2 years, each patient was free of infection. Hence, partial component-retained two-stage reconstruction could be a choice for treatment in such patients for infected total hip arthroplasty with a well-fixed component.
