多半径与单半径全膝关节假体的研究进展

Research progress in multiple-radius prosthesis and single-radius prosthesis in total knee arthroplasty

全膝关节置换术是目前治疗晚期膝关节骨性关节炎最有效的手段,常用的股骨端假体设计包括多半径和单半径两种。尽管单半径假体在设计理念上优于多半径假体,然而对于两种假体在临床中的实际疗效还存有诸多争论。本文从两种膝关节假体的生物力学、临床功能评分、运动学、满意度和生存率等方面进行了比较,对多半径假体与单半径假体的研究进展及未来的研究方向进行综述。

Total knee arthroplasty is the most effective treatment for advanced knee osteoarthritis currently. Common femoral prosthesis designs include the multiple-radius and the single-radius. Although the design of single-radius prosthesis is theoretically superior to multiple-radius prosthesis, there are still many debates on the two prostheses in actual clinical efficacy.This article compares the biomechanics, clinical function scores, kinematics, satisfaction, and survival rates of the two kinds of knee prosthesis. The research status and future research directions of multiple-radius prosthesis and single-radius prosthesis are summarized.
