Abstract
This review is devoted to modern technologies for various modifications of a surface of orthopedic implants made from titanium alloys. This approach will allow improving such characteristics of the implants as a corrosion resistance, biocompatibility and osteointegration. Modifications of titanium alloys with hydroxyapatite and calcium phosphate, multifunctional polymer or antibacterial coatings are considered. Analysis of the studies shows that the implant material can only provide a certain degree of biocompatibility and corrosion resistance, and that the nature and design of its surface have a strong influence on the body's response. Surface modification of implants is a good approach to overcome and solve various problems associated with the disadvantages of titanium alloys for orthopedic implants.
