Background Total hip replacement (THR) is extremely common. Some prostheses fail,
particularly in younger patients, and need to be revised, most commonly for loosening …

Background Implant survival after conventional total hip replacement (THR) is often poor in
younger patients, so alternatives such as hip resurfacing, with various sizes to fit over the …

The metal-on-metal bearing couple is having a resurgence in clinical applications seen in
total hip and hip resurfacing technologies. The most noteworthy advantage of a metal-on …

Background: Total hip arthroplasty in patients younger than thirty years of age represents a
long-term challenge. As polyethylene wear secondary to a high activity level could be …

Background Adverse reactions to metal debris (ARMD) have resulted in the high short-term
failure rates observed with metal-on-metal hip replacements. ARMD has recently been …

Lately, concerns have arisen following the use of large metal-on-metal bearings in hip
replacements owing to reports of catastrophic soft-tissue reactions resulting in implant failure …

This study reports the mid-term results of a large-bearing hybrid metal-on-metal total hip
replacement in 199 hips (185 patients) with a mean follow-up of 62 months (32 to 83). Two …

Objective To determine whether use of metal-on-metal bearing surfaces is associated with
an increased risk of a diagnosis of cancer in the early years after total hip replacement and …

Periprosthetic osteolysis caused by wear debris released from the bearing surface of
polyethylene components is the major problem in contemporary hip arthroplasty. Several …

There is emerging evidence that many metal-on-metal (MoM) bearings, when used with
large femoral heads in conventional hip replacement and some resurfacing prostheses, are …
