Abstract

Removal of well-fixed, cementless metal-backed patellar components can be difficult due to lack of easy surgical access to the anchoring pegs. Five cases of total knee arthroplasty with failed metal-backed cementless patellar components with ingrown anchoring pegs are presented. A technique of removal of these components is described that preserves remaining patellar bone and provides easy access to the well-ingrown anchoring pegs, lessening the risk of fracture during patellar component extraction.
