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

The objective of this workshop was to provide a forum to discuss the reintroduction of metal
on metal bearings for clinical use in total hip arthroplasty. Approximately 100 researchers …

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 …

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 …

The 20-year performance of metal-on-metal hip articulations has not been reported. Five
McKee—Farrar total hip prostheses and one Sivash prosthesis were obtained at revision …

Metal-on-metal bearings have wear rates that are 20 to 100 times lower than metal-on-
conventional polyethylene. The amount of wear generally is the same order of magnitude for …

High volumetric wear of polyethylene plays a central role in periprosthetic bone resorption
and the failure of metal on polyethylene total hip resurfacing prostheses. An assessment of …

A major concern in total hip arthroplasty is the generation of polyethylene wear particles at
the articulating surfaces and resulting macrophage mediated periimplant osteolysis. There is …

Research has recently been focused on the development of hip replacements with
alternative bearing surfaces with cobalt chrome alloy, to avoid the production of …

Larger diameter metal-on-metal (MOM) bearing hips offer the possibility of low wear and
reduced risk of dislocation. We reviewed the first 126 patients (131 hips) who had a large …
