A graphitic layer is found to be the cause of low friction in metal-on-metal hip implants. Arthritis is a leading cause of disability, and when nonoperative methods have failed, a prosthetic implant is a cost-effective and clinically successful treatment. Metal-on-metal replacements are an attractive implant technology, a lower-wear alternative to metal-on-polyethylene devices. Relatively little is known about how sliding occurs in these implants, except that proteins play a critical role and…

Tribological interactions of metal in total hip arthroplasty (THA)

TLDR
Wear debris in MOM hip replacements is now thought to be implicated in causing a local soft-tissue inflammatory response leading to premature failure of the implant.

Tribology, corrosion and tribocorrosion of metal on metal implants

Abstract Metal on metal joint replacements are considered as an alternative to metal on polyethylene implants, especially in case of young patients who require a safe and long term performance of the

Tribo-biological deposits on the articulating surfaces of metal-on-polyethylene total hip implants retrieved from patients

TLDR
Results showed that the attached tribo-layer contained not only denatured proteins but also a fraction of polymer particles, suggesting that enhancing interface lubrication may be more effective on reducing wear than increasing the hardness of material.

CoCrMo metal-on-metal hip replacements.

TLDR
This perspective article is intended to outline some recent progresses in understanding wear and corrosion of metal-on-metal hip replacement both in vivo and in vitro.

Friction and Wear Characteristics of Surface-Modified Titanium Alloy for Metal-on-Metal Hip Joint Bearing

Cobalt-chromium-molybdenum bearing materials have excellent wear resistance, but due to the cytotoxicity issue of chromium ions, they need to be replaced with biocompatible metal materials. Titanium

Electrochemically Induced Film Formation on CoCrMo Alloy for Hip Implant Application

Metal-on-metal (MoM) hip retrievals exhibited the presence of carbonaceous tribofilms, derived from synovial proteins, particularly on the articulating surfaces. Studies suggest that the films

TLDR
The present study suggests that the use of metal on metal articulating surfaces may mitigate the problem of osteolysis by offering improved wear performance.

TLDR
It is found that the tribolayers are nanocrystalline in structure, and that they incorporate organic material stemming from the synovial fluid, which provides the basis for understanding particle release and may help in identifying new strategies to reduce MoM wear.

TLDR
Mixed lubrication was found to occur in the metal-on-metal (CoCrMo/CoCr Mo) joints with all lubricants at a viscosity within the physiological range, and a strong correlation was observed between experiment and theory when employing CMC fluids or silicone fluids as the lubricant.

In vivo wear of three types of metal on metal hip prostheses during two decades of use.

TLDR
Metal on metal hip replacements, including McKee-Farrar, Müller, and Ring, that were retrieved from patients after as many as 25 years showed early wear included substantial third body abrasion, possibly from particles generated while scratches from the original polishing were being eradicated and from dislodged surface carbides.

Metal-on-metal joint replacements have been considered an effective alternative to metal-on-polyethylene bearings. Various electrochemical and spectroscopic techniques have been used in studying the

Adverse reaction to metal debris following hip resurfacing: the influence of component type, orientation and volumetric wear.

TLDR
Increased wear from the metal-on-metal bearing surface was associated with an increased rate of failure secondary to ARMD, however, the extent of tissue destruction at revision surgery did not appear to be dose-related to the volumetric wear.
