Aseptic loosening of the prosthesis is a major form for the failure of artificial joints, which results in the conglomeration of wear particles at the bone-implant interface. This paper briefly reviews the recent development of tribology of artificial joints preserving good lubrication, enhancing the wear resistance of materials for the joints, reducing the generation of sensitive-size particles and depressing the debris-tissue reactions. Suggestion for improvement in the design of artificial joints is presented.
假体无菌性松动是人工关节失效的主要形式，它导致磨损颗粒在骨-植入物界面聚集。本文简要综述了人工关节摩擦学的最新进展，包括保持良好润滑、提高关节材料耐磨性、减少敏感尺寸颗粒的产生以及抑制碎屑-组织反应。并提出了人工关节设计改进的建议。
