【摘要】 内轴型膝关节假体自1999年上市以来,已被越来越多的应用到临床上。从设计原理上,内轴型膝关节假体系统较传统膝关节置换系统有显著优势,可最大程度的恢复正常的髌股关节和胫股关节活动,并且使用最接近膝关节解剖形态的股骨假体设计,提高了关节活动的稳定性,同时增加关节面的接触面积,最大程度降低了聚乙烯的磨损。但有关内轴型膝关节假体置换术后中远期随访研究相对较少,大宗的研究数据亦不多见,这些文献研究中绝大多数为针对欧美国家人群的研究,针对中国人置换该系统后的中远期随访目前无相关报道。本文通过广泛阅读国内外相关文献,总结内轴型假体临床应用的相关研究进展,指出目前研究的不足。更多还原

【Abstract】 Medial pivot knee prosthesis has been widely applied in clinical practice since it became commercially available in 1999. From the design principle,compared with the traditional knee replacement system,the medial pivot kneeprosthesis has some significant advantages: 1) it can largely restore movements of the patellofemoral joint and the tibiofemoral joint; 2) because the designed prosthesis is closed to the anatomical structure of knee joint,it can improve the stability of joint motion and increase the joint contact area to minimize the abrasion of polyethylene. However,there are few studies on medial pivot knee prosthesis with mid- and long- term follow- up and the studies with a large sample size are also rare. Most studies were reported on people from Europe or America. There are no similar reports on Chinese people. This paper summarizes the research progress in the clinical application of medial pivot knee prosthesis and indicates the limitations of currently published studies by reviewing the relevant literature.更多还原
