problems with uncovering of acetabular cup after THR. 2 years ago.
I have recently had a hip arthroscopy to have a iliopsoas tendon release and removal of dense scar tissue. My total hip replacement was done two years previously. But the acetabular cup was found to be uncovered between 12 and 3 o clock, meaning that the fixation beads (uncemented pinnacle cup) were exposed and separating due to the iliopsoas tendon rubbing against them. Could someone tell me whether this was a mistake of the original surgeon to leave the cup like this or could this have loosened to become uncovered over time, as two xrays have shown signs of possible loosening but both times it has been ruled out due to the surgeons saying it is a stable joint. I am still in pain two months after the arthroscopy and although it was done this way in the hope that the simple procedure would do the trick but was proved that the more definitive solution would have been to revise the acetabular cup to cover the cup in the bone. but this would have meant major surgery. ! -as stated by the surgeon. I just want to know why it was like this and should the original surgeon be to blame for this and what i should do
It could have occurred either way with improper fixation technique or due to wear and tear of the joint. I would suggest discussing this with your orthopedic surgeon or you may seek a second opinion with another orthopedician to be sure regarding the further management plan.
Hope this helps.
