Unwanted physiological reactions, caused by particle release in articulating joints, are still a
major concern in total hip arthroplasty. Diamond-like carbon coatings (DLC) show very low
wear values in many technical applications. Attempts to transfer these outstanding
tribological properties to in-vivo load bearing articulating joints turned out to be extremely
problematic. A DLC coated metallic metatarsophalangeal (MTP) prosthesis, with both
articulating surfaces coated, was explanted after approximately 4years. The DLC-coating …
