Implant survival, range of motion, and complications of proximal interphalangeal joint arthroplasty have been reported often, but patient-reported outcomes are less frequently described. This study evaluated patients' experiences during the first year after proximal interphalangeal joint arthroplasty, measured with the Michigan Hand Outcomes Questionnaire (MHQ). The primary focus was the reduction of patient-reported pain after proximal interphalangeal joint implant placement and the percentage of patients who considered this reduction clinically relevant, indicated by the minimal clinically important difference (MCID).
