Resection arthroplasty

removal of one or both articular surfaces of a joint, usually as a salvage procedure after failure of a total joint replacement operation. Often the cause of failure is infection. An example of this type of procedure is the Girdlestone arthroplasty, in which extensive debridement and resection of para-articular bone are employed. As a consequence of this operation, the affected extremity is shortened and the patient develops joint instability and a Trendelenburg gait.
