title: Radiographic pseudochondrocalcinosis in early failure of a cemented total knee replacement.
abstract: We observed a case of early-onset osteolysis in a cemented total knee arthroplasty. Preoperative radiographs suggested numerous radiopaque particles covering the polyethylene insert. Findings at the time of revision confirmed the presence of small radiopaque polymethylmethacrylate particles on the bearing surface of the tibial insert, presumably leading to early failure of the knee arthroplasty.
