用于经股截肢者的当前最先进的假肢仅通过受控阻尼或通过完全动力步态模仿来操作。被动装置不能恢复自然步态，而主动装置体积大且效率低。本文总结了一种新的半主动假肢膝关节的设计，它结合了被动阻尼液压装置的安全性和动力效率，以及全主动装置的步态改善和先进的移动性。
Current state-of-the-art prostheses for transfemoral amputees operate exclusively through controlled damping or through fully powered gait imitation. The passive devices cannot restore a natural gait, and the active devices are large and inefficient. This paper summarizes the design of a new semi-active prosthetic knee that combines the proven safety and power efficiency of a passively damped hydraulic device with the improved gait and advanced mobility of a fully active device.
