Painful knee prosthesis: can we help with bone SPECT/CT?

Materials and methods Between 2009 and 2011 we identified 105 patients who had undergone Tc-hydroxydiphosphonate SPECT/CT for painful knee prosthesis. Complete follow-up data were available for 69 patients (50 women and 19 men; mean age, 71 years) with painful knee prostheses (59 total, nine unicompartmental, one patellofemoral) and clinical suspicion of infection or loosening. The imaging test report in conjunction with the clinical data from the patient’s notes was used to gauge how useful the test had been in terms of patient management.
