The rationale behind implant coatings to promote osteointegration, bone healing or regeneration

Injury. 2021 Jun:52 Suppl 2:S106-S111. doi: 10.1016/j.injury.2020.11.050. Epub 2020 Nov 21.

Abstract

Implant loosening, bone healing failure, implant-associated infections, and large bony defects remain challenges in orthopedic surgery. Implant surface modifications and coatings are being developed to promote osteointegration, prevent colonization by bacteria, and release bioactive factors. The following mini-review briefly discusses the clinical problem, explains the four "osteos", presents examples of coatings used for different orthopedic indications, and finally raises awareness of the coating and translational requirements.

Keywords: Arthroplasty; Coating; Defect; Fracture healing; Osteoconduction; Osteogenesis; Osteoinduction; Osteointegration.
