Points in the technique of recementing in the revision of an implant arthroplasty.

When aseptic failure of the bond between the cement and the prosthesis of a total joint replacement occurs, complete removal of the cement has been advocated before the insertion of a new prosthesis. The present study questions this practice. Both laboratory tests on variously prepared specimens of cement and clinical experiences demonstrate that recementing over old cement is a practical alternative if the technique employed includes the removal of blood from the old cement surface, rasping of this surface and the early application of fresh cement.
