This was a bil revision done in 2002 for failed bil MOP surface replacament with MOP. came with groin pain and pain on wt bearing . bone scans were normal. no cysts but superior poly wear ( enduron poly)was close to Metal on metal articulation. hence revision was planned. surprisingly the cemented cup on the rt showed hardly any wear
Revision was planned to change poly and head. Unfortunately JNJ has with drawn the implants so new poly liner and ceramic head was unavailable.
Plan A . was to cement a cemented cup after roughening the inner surface of the cup and change the head
Plan b. If femoral taper was damaged to go for a full revision.
as taper was not damaged a cup was cemented after roughening with a carbide disc and burr and metal head was changed
