Assessing the influence of gastrocnemius reconstruction on stress distribution of femoral tumor rotating hinge knee prosthesis via finite element analysis [PDF]
Frontiers in Bioengineering and BiotechnologyBackground:After femoral oncological knee arthroplasty, some patients suffer from rotating axis fracture, which significantly impacts the life span of the rotating hinge knee (RHK) prosthesis.

Journal of Biomechanical Science and Engineering, 2009 To evaluate motions and joint reaction forces of the total knee prosthesis during deep knee flexion such as kneeling and sitting straight, a simulator that reproduces the passive motion of the knee has been developed. The main feature of the simulator is

Alignment of the above-knee prosthesis/1 [PDF]
Prosthetics & Orthotics International, 1979 1. A long prosthesis forces drop of the pelvis on the normal side, can cause crotch pressure and distal femoral pressure leading to discomfort, can reduce voluntary control, may force the amputee to walk with an abducted stump hip for stance phase and to swing the leg outward for toe clearance in swing phase or to compensate by rising up on the sound ...

A Power-Capable Knee Prosthesis With Ballistic Swing-Phase
IEEE Transactions on Medical Robotics and Bionics, 2022 This paper proposes a new approach to the design of a power-capable prosthesis; namely, one that expands the behavioral capability of a knee prosthesis into the powered quadrants of the power plane, without sacrificing the range of capable behaviors in ...

Effect of a Swing-Assist Knee Prosthesis on Stair Ambulation
IEEE transactions on neural systems and rehabilitation engineering, 2021 This paper describes stair ambulation control and functionality of a semi-powered knee prosthesis that supplements nominally passive prosthesis behavior with swing-phase assistance. A set of stair ascent and descent controllers are described.
