Berry reviews the epidemiology of intraoperative and postoperative periprosthetic fractures around THA and TKA by anatomic site, using Mayo Clinic joint registry data from over 30,000 hip and 19,000 knee arthroplasties to characterize fracture rates, demographics, and risk factors at each location.
When planning uncemented revision THA, counsel patients that intraoperative femoral fracture risk exceeds 20% — far higher than the 1% seen in primary cemented cases. And have a fixation strategy ready.
When you see a postoperative periprosthetic fracture around a well-fixed uncemented socket or femoral stem in a patient with known osteolysis, recognize osteolysis-driven bone loss as the likely predisposing mechanism rather than implant failure alone.
