Abstract
With advances in materials science and biology, there have been continuing innovations in the field of artificial joint prostheses. Cementless prostheses have the advantages of long service life, easy revision, and good initial stability and are widely used in artificial joint replacement. Coatings are the key to cementless prostheses and are at the heart of their excellent functionality. This article mainly studies the clinical application of hydroxyapatite (HA) coating, standard porous coating represented by Porocoat coating, and new high-porosity coating represented by Gription coating. The clinical application and biological functionalization of different artificial joint prosthesis surface coatings are clarified, and it provides a reference for the clinical selection and development of different prosthesis surface coating materials.

We mainly studied the surface coatings of three commonly used biological prostheses, namely hydroxyapatite (HA) coating, Porocoat coating, and Gription coating
Summary
Joints such as hips and knees are all weight-bearing joints that are subject to complex forces. Katz et al [3] conducted a study on 83 cases of cemented hip revision surgery and found that the results of cemented hipurgent revision were not satisfactory, and aseptic rate was a there is an need to increase the service lifethe of reported prostheses. The tissue surface roughness ofrevisions the prosthesis, thereby improving initial highgrowth failure and rate the of cemented prosthesis promotes the use of the cementless stability of the prosthesis reducing looseness. Coating studies on joint prostheses haveprosthetic focused on tothe clarify the clinical application and biological functionalization of different initial coatings stability, osseointegration, and antibacterial aims to clarify the surface for artificial joints and to provideproperties.
