Patient Question: Hi Dr. Xie: I would like to know the difficulty and worst outcome of having a second surgery or revision surgery after 15 or 20 years of age after having a hip replacement. If it fails, you will spend the rest of your life in a wheelchair. Doctor’s reply: There are two problems here: one is that the idea of needing a revision after 15-20 years is wrong, this is based on the premise of using ordinary HPPE lining, nowadays young patients use ordinary HPPE lining less and less, if you use ceramic to ceramic or high cross-linked polyethylene lining may be used for a lifetime, so revision is not inevitable. The second is that although revision surgery is difficult compared to initial replacement, 85% of revisions are not very difficult, and in addition this difficulty is relative and understood differently by doctors with different experiences. Also, particularly difficult revisions are often due to severe bone defects caused by too much osteolysis due to wear particles of ordinary polyethylene, so the culprit is still polyethylene, so as long as ordinary polyethylene liners are not used there will not be as many problems.
