Osteolysis around total knee arthroplasty components has been described predominantly in association with posterior cruciate ligament-retaining knee designs1-4. Most of these implants had been inserted without bone cement and had relatively nonconforming articular surfaces and a thin tibial polyethylene insert5-9. In contrast, to our knowledge, neither clinically apparent wear of the polyethylene of the tibial component nor extensive osteolysis has been reported in association with the classic posterior stabilized total knee prosthesis (Insall-Burstein; Zimmer, Warsaw, Indiana)10,11.
