I had hip replacement in 2000. This lasted for 1 week, displace twice. Went back to hospital and the emergency crew had an awfull time in getting joint replaced. Finally they carried me to surgery room where a surgeon put it back.
I came home and it displaced again. The surgeon that did the first surgery could not understand the problem so he opened the surgery and put in a replacement with a cup with a a cap. After this surgery my sciatic nerves was not workin.
So after 10 years i have had to put up with nerve damage and foot drop with no hope for recovery. My doctor said it was caused basically from emergency room doctors just beating up my sciatic nerves.
