Abstract

As materials for arthroplasty, titanium alloys exhibit the following advantages over conventional steel, cobalt chromium or chromium nickel alloys – good fatigue strength, excellent biocompatibility, low modulus of elasticity, and high corrosion resistance. The previous worse clinical outcome was most likely caused by crevice corrosion and led to reduced use. To warrant safe use, the design should be optimised (sufficient proximal diameter, proximal collar), in order to reduce unwanted deformation in the proximal part of the prosthesis. Additionally, a rough surface (Ra > 2.5 µm) should not be used. Further research in surface treatments (e. g. silicate-silane) could facilitate additional improvement.
