Loosening - A prosthesis may become loose within the bone after a total joint replacement due to a failure of the bone cement or a failure of your bone to grow into your implant properly. This may cause pain or damage to the surrounding bone, and your joint may have to be repaired or replaced. Dislocation - Occasionally after total hip replacement, the ball can become dislodged from the socket. This can usually be fixed without surgery. A brace may be used after a dislocation.
Dislocations are more common after complex surgeries.
Wear - Some wear of the joint surface is to be expected. However, excessive wear may lead to the need for further surgery. Wear of the joint surface can cause small particles of artificial material to be distributed around the joint. Prosthetic breakage - Breakage with modern materials anq implants is rare. If it occurs, replacement surgery is generally needed.
