Dynamics of a Running Below-Knee Prosthesis Compared to Those of a Normal Subject

The normal human running has been simulated by two-dimensional biped model with 7 segments. Series of normal running experiments were performed and data of ground reaction forces measured by force plate was analyzed and was fitted to some Fourier series. The model is capable to simulate running for different ages and weights at different running speeds. A proportional derivative control algorit...

Conservative Bone Cuts and Technical Hints Incruciate Retaining Total Knee Arthroplasty, a 20 Years Experience

Total knee arthroplasty (TKA) is one of the most successful procedures in modern orthopedic surgery, providing high patient satisfaction rate. As a result, the number of patients undergoing TKA is increasing in number every year and more patients would be inclined to have the operation in near future . The demand for TKA is expected to grow 673% between 2005 and 2030. Knee surgeons are using mo...

Contact stresses and fatigue life in a knee prosthesis: comparison between in vitro measurements and computational simulations.

The evaluation of contact areas and pressures in total knee prosthesis is a key issue to prevent early failure. The first part of this study is based on the hypothesis that the patterns of contact stresses on the tibial insert of a knee prosthesis at different stages of the gait cycle could be an indicator of the wear performances of a knee prosthesis. Contact stresses were calculated for a mob...

Design of an Agonist-Antagonist Knee Prosthesis for Experiments in Human Locomotion

We previously developed an ankle-foot prosthesis emulator with exceptional versatility [1]. It is lightweight, capable of producing large torque and power, and can quickly change behaviors [2]. However, it cannot fully address the needs of trans-femoral amputees. In the commercial market there are many active knees such as the Ottobock C-leg and Össur Power Knee. These are successful products, ...

The effect of knee orthosis on co-contraction values of knee and ankle muscles during running in people with knee deformity in the frontal plane.

Background and Aims: the use of knee orthosis changes the mechanics of running. One of the important biomechanical factors in rehabilitation and injury prevention is co-contraction of knee and ankle joints. Therefore, the aim of the present study was to investigate the effects of knee orthosis on changes in the contraction of knee and ankle muscles during running in people with genu varum. Mat...
