Total knee arthroplasty (TKA) is one of the most commonly performed surgical procedures in the United States. There are concerns and reports of early aseptic loosening due to debonding at the cement-implant interface in a specific posterior-stabilized femoral design. This study describes failure at the cement-implant interface …
