What is meant by hip revision surgery?

Hip revision surgery is the procedure in which a surgeon replaces a previously implanted hip with a new prosthesis, according to the Encyclopedia of Surgery. It is also called arthroplasty.

Hip revision surgery is conducted to relieve pain in the affected hip, restore mobility and remove a loose or damaged artificial hip, according to the Encyclopedia of Surgery. Increasing pain in the affected hip is the first indicator that this surgery may be necessary. A surgeon conducts this procedure only after medication and lifestyle changes have failed. Hip revision surgery often requires the use of bone grafts, using bone from another site in the patient's own body or from a donor.
