You’ll need hip revision surgery to replace your artificial joint if this becomes loose, wears out or breaks. This can be a much more complicated operation than your original hip replacement. Your surgeon will need to remove the original implants and any cement used to hold them in place. Then they’ll be able to put the new implants in. Some implants can be more difficult to remove than others. If your thigh bone has grown onto the implant, this can make the implant difficult to remove. Your bones get thinner as you get older and are more likely to break (fracture). Your surgeon might need to use a hip replacement part with a longer stem to get a stronger fix into the bone. Your surgeon may have to rebuild the bone in your hip using bone from another part of your body or from your thigh. This is called a bone graft. If you need to have a bone graft, it may take you longer to recover and you may need to use crutches for longer.
