We have developed a new surface architecture for orthopaedic stem components which incorporates a multitude of tiny anchor features for embedding into the bone during implantation. It provides improved primary fixation compared to existing surface coatings.
OsteoAnchor uses a 3D printed surface architecture to gently but securely embed into the patient’s host bone, resulting in improved primary fixation and resistance to micromotions once the patient starts walking again. A network of interconnected pores underneath the claws ensures proper in-growth of hard bone, and excellent long-term fixation.
The surface incorporates a multitude of tiny anchor features which embed into the bone during implantation that can provide up to 76% greater resistance to transverse motion under simultaneous normal loading compared to porous tantalum.
OsteoAnchor implants provided superior primary fixation performance compared to the control plasma-sprayed titanium implants.
