An ankle-knee synchronous mechanism in a new endoskeletal above-knee (A-K) prosthesis has been designed and a preliminary clinical study has been conducted. A revision of the knee mechanism which is mainly focused on the basis of reducing the energy cost of the prosthetic wearer has been developed. It provides multiple position of the knee lock. It also provides anterior placement of the knee joint and a synchronous motion with the ankle joint. It enables the prosthetic wearer to minimize the effect of hip extensor contraction, to stabilize the knee, and maximize the sense of security and to balance the body over the artificial limb through the stance phase of gait. It permits the amputees to assume various body postures which enable them to perform daily activities. A new concept for alignment of A-K prosthesis is accomplished by using a weight bearing line instead of a trochanter and ankle (TKA) line, especially for the short A-K amputees. Deletion of the inertia control mechanism becomes possible by simply inserting a bumper in the knee to prevent terminal impact at swing phase and a built in coil spring acts as a knee extension aid.
一种新型内骨骼大腿假肢的踝膝同步机构已被设计出来，并进行了初步临床研究。已开发出一种主要基于降低假肢佩戴者能量消耗的膝关节机构改进方案。它提供了膝关节锁定的多个位置。它还使膝关节向前放置并与踝关节同步运动。它能使假肢佩戴者在步态支撑期将髋伸肌收缩的影响降至最低，稳定膝关节，最大限度地提高安全感，并通过假肢平衡身体。它允许截肢者采取各种身体姿势以进行日常活动。一种新型大腿假肢对线概念是通过使用负重线而非转子和踝关节（TKA）线来实现的，特别是对于大腿截肢较短的患者。通过在膝关节中简单插入一个缓冲器以防止摆动期的终端冲击，删除惯性控制机构成为可能，并且内置的螺旋弹簧起到膝关节伸展辅助作用。
