Ankle-Knee prosthesis with powered ankle and energy transfer for CYBERLEGs α-prototype

International Conference on Rehabilitation Robotics, 2013
Restoring natural walking for amputees has been increasingly investigated because of demographic evolution, leading to increased number of amputations, and increasing demand for independence.

Parametric Modelling of a Knee Joint Prosthesis

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 1993
This paper presents an approach for the establishment of a parametric model of knee joint prosthesis. Four different sizes of a commercial prosthesis are used as an example in the study. A reverse engineering technique was employed to reconstruct the prosthesis on CATIA, a CAD (computer aided design) system.

The Bi-Unicompartmental Knee Prosthesis

2013
The bi-unicompartmental knee prosthesis [1, 2, 3, 4, 5] is a system that uses two independent components, femoral and tibial, to preserve the tibial eminentia with the anterior cruciate ligament (ACL). Although in the majority of prosthetic knee systems the cruciate ligaments are sacrificed or only the posterior cruciate ligament (PCL) is preserved, a ...

CYBERLEGS Beta-Prosthesis active knee system

International Conference on Rehabilitation Robotics, 2015
The addition of active components to prostheses has the potential to extend the capabilities and reduce metabolic energy consumption of users when compared to current prosthetic technology.

Unicondylar knee prosthesis: our experience.

Acta bio-medica : Atenei Parmensis, 2014
To compare unicompartmental knee arthroplasty with "all poly" tibial component and "metal back" from a clinical and functional point of view.We evaluated prospectively 50 patients who underwent unicompartmental knee replacement at the Orthopedic Clinic of the University of Trieste. Patients were split into two groups (A and B); in patients from group A

The Posterior Stabilized Knee Prosthesis [PDF]

, 1991
If the Total Condylar prosthesis proved to be so successful, why then was the Posterior Stabilized version designed and introduced into clinical practice? There are several reasons. It must be remembered that the Total Condylar, a cruciate sacrificing design, was conceived from the outset as part of a system of progressively more constrained devices ...

The Total Condylar Knee Prosthesis

1991
Few topics in the orthopaedic literature have become more boring or contentious than the recitation of good surgical results, especially when a prosthetic device is involved. Nonetheless, these devices and the operations devised for them must be assessed. This type of clinical research should identify the principles of the design and surgical technique

Total Knee Replacement with a Variable Axis Knee Prosthesis

Orthopedic Clinics of North America, 1982
The Variable Axis Knee Prosthesis was designed to accommodate a wide range of problems in the knee and to minimize the complication of loosening. The results of the series, which now spans over seven years at this institution, have confirmed the effectiveness of the prosthesis in providing stability and firm fixation.

The PCA total knee prosthesis

1986
The Porous Coated Anatomic “Total Knee replacement, implanted with the use of the Universal Total Knee Instruments” was designed to reproduce physiologic, anatomic alignment of the lower extremity and to resurface the femoral, tibial, and patellar aspects of the knee permitting normal kinematic motion patterns.
