Devices are commonly implanted during orthopaedic surgical procedures for fracture fixation, spine stabilization, total joint replacement and in numerous other subspecialties. Traditionally these implants have been made of non-biodegradable metals, polymer, and ceramics, and more recently, fully or partially biodegradable materials. These devices must interact with host tissues to obtain a final desired clinical goal with few or no adverse events. More recently, it has been realized that surface modifications and coatings of an orthopaedic device may improve the chances of achieving the desired outcome. Examples include coating of devices implanted into bone with bioceramics, growth factors and other molecules to accelerate fixation and implant osseointegration, coatings that deliver molecules to prevent or combat infection and composite tissue coated implants.
This special issue on "Biologic Coatings for Orthopaedic Implants" for the International Journal of Molecular Sciences will focus on such novel coatings for orthopaedic implants, including basic and applied science and their potential clinical application. This information will help further the scientific principles underlying coating technology and their applications in the hope that patient care will be enhanced.

Title: Osseointegration of Bioactive Plasma-Polymerized Implant Surfaces in an Animal Model

Abstract: Objective: Due to plasma polymerization it is possible to apply positively charged, nanometer thin coatings to the implant surfaces for the enhancement of adhesion and ingrowth of osteoblasts. The aim of the present study was to evaluate the osseointegration and bone-to-implant contact of implants coated with bioactive plasma polymers using an animal model. Materials and Methods: Custom-made conical titanium implants with a rough surface (Rz=20µm) were inserted at the tibia of female Sprague-Dawley rats. Three implant configurations were examined: uncoated, coated with plasma-polymerized allylamine (PPAAm) and coated with plasma-polymerized ethylendiamine (PPEDA). Animals were sacrificed after six weeks. Bone-to-implant contact was determined by means of histomorphometry. Results:The data indicate the tendency that the implants with plasma-polymerized coatings (PPAAm and PPEDA) lead to higher bone-to-implant contact compared to the uncoated TiAl4V implant. Conclusion:With respect to previous cell investigations we can demonstrate an advanced ongrowth of bone cells on PPAAm or PPEDA coated surfaces in animal experiments. Plasma polymer coatings reveal positive influence on “race for the surface” of bone cells and therefore should have beneficial effects on the osseointegration of titanium implants in clinical application.
