The Reasons Hip Replacements Wear Out
Hip replacements can wear out for a variety of reasons but by far the most common cause is 'aseptic loosening’. Aseptic loosening occurs when the hip implants become loose within the bone. A loose hip implant tends to be painful, and usually requires revision hip replacement.
Other causes of a wear include infection, breaking of the prosthesis, breaking of the bone around the prosthesis, and other complications. Depending on the cause of the implant failing, treatment other than revision hip replacement may be needed. For example, in the case of infection, the hip replacement may need to be removed to treat the infection, followed by the revision hip replacement months later.
