Sixty-eight well-fixed acetabular cups with @entity3061 in the pelvis and @entity691 wear were identified from a series of 124 reoperations for failed cementless sockets. The well-fixed sockets requiring reoperation were subdivided based on whether the liner was exchanged and @entity75 grafted (Type I case) or the socket was removed and a complete revision was done (Type II case). In 40 @entity1 (Type I cases), the @entity691 liner was exchanged and the @entity690 were debrided. Allograft bone chips were packed into the lytic defect in 29 @entity1 . In the remaining 11 @entity1 , the lesions were debrided but not grafted. At final followup, all of the acetabular components were radiographically stable. No new @entity690 were identified. Approximately 1/3 of the lesions had resolved completely regardless of whether they were grafted. The remaining 2/3 had decreased in size. In 28 @entity1 (Type II cases), the socket was revised. Both strategies were successful in arresting the process of @entity3061 during the course of this study (mean, 3.5 years). However, removal of well-fixed sockets was associated with significantly more @entity604 .
