非骨水泥假体在全膝关节置换术中的应用进展

全膝关节置换术(TKA)是治疗膝关节终末期骨关节炎及风湿性关节炎的有效手段，传统的骨水泥假体在TKA中应用一直占据主流地位。针对年轻患者(≤60岁)和有运动需求的患者而设计的非骨水泥假体在早期由于设计和技术上的限制，未能获得较好的预后，因此没有得到广泛推崇。随着设计理念及材料技术的提升，新型非骨水泥假体优势突显，逐渐受到关节科医生的青睐。本文就非骨水泥假体的设计初衷、发展历程、新技术特点、临床预后以及目前研究的不足等角度出发，对非骨水泥假体在TKA中的应用进行全面的综合评述。

Application progress of cementless fixation prostheses for total knee arthroplasty

Total knee arthroplasty (TKA) is an effective treatment for advanced osteoarthritis (OA) and rheumatoid arthritis (RA) of the knee. Cemented fixation implants are widely referred by orthopedic surgeons. Cementless prostheses which are designed and applied for younger (≤60years old) and more active patients, do not gain great favor over cement prostheses for the sake of poor design and material technique, leading to frequent TKA failure and unpleasing outcome. However, the latest generation of cementless fixation prostheses are gradually considered as a reasonable option among TKA processes attributed to the development of prostheses design and material technique. This article reviewed the history and current application, newest characteristics and the research disadvantage of cementless TKA.
