Russian Scientists Develop Coatings to Improve Orthopaedic Implant Integration

KALININGRAD: Researchers at Immanuel Kant Baltic Federal University (IKBFU), in collaboration with colleagues, have successfully tested a new bioactive material for orthopaedics based on the natural mineral hydroxyapatite with the addition of nitrogen oxide, as reported by tv BRICS.
Traditional implants made from titanium alloys are highly durable but lack sufficient bioactivity, limiting their ability to integrate with living tissue. This can lead to implant failure or bacterial infections.
To overcome these challenges, researchers coated titanium implants with hydroxyapatite, a mineral similar in composition to bone tissue, and added nitric oxide for antibacterial properties. The coating can stimulate tissue healing, improve blood supply, and inhibit bacterial growth.
Biomedical testing has shown the material’s high biocompatibility. Cells on the coated surface survived much better than on bare titanium without the coating.
"The use of nitrogen-enriched calcium phosphate coatings is a promising approach that could help create a healing microenvironment around implants, thereby addressing the problem of body rejecting medical devices," said Vladimir Malashchenko, a research fellow at the Centre for Immunology and Cellular Biotechnology at IKBFU.
The scientists aim to continue studying the effects of nitric oxide on living tissue, paving the way for personalised medical solutions that enhance patient recovery and reduce complications after orthopaedic surgery.
