Core Tip

Core Tip: The routine treatment method for patellar fractures with knee osteoarthritis (OA) is staged surgery in which the patellar fracture is fixed first, then total knee arthroplasty or unicompartmental knee arthroplasty (UKA) is performed after the patellar fracture heals. We report a case of patellar fracture with anteromedial OA, we performed open reduction and internal fixation combined with Oxford UKA for this patient in a single stage, and she showed excellent postoperative clinical results. For elderly patients, single stage surgery reduces the risk of anesthesia and surgery, followed by less postoperative pain and cost.
