Individuals with lower limb amputation commonly exhibit large gait asymmetries that are associated with secondary health issues. It has been shown that they are capable of attaining improved temporal and propulsive symmetry when walking with a powered ...

Control of prosthesis swing trajectory enables individuals to voluntarily change foot clearance to traverse obstacles. Powered prostheses aim to mimic the missing biological limb with controllers that are finely tuned to replicate the nominal gait ...

A circumferentially flanged tibial tray minimizes bone-tray shear micromotion [PDF]
Aseptic loosening of the tibial component is the major complication of total knee arthroplasty. There is an association between early excessive shear micromotion between the bone and the tray of the tibial component and late aseptic loosening.

Structural Simulation of a Bone-Prosthesis System of the Knee Joint
In surgical knee replacement, the damaged knee joint is replaced with artificial prostheses. An accurate clinical evaluation must be carried out before applying knee prostheses to ensure optimal outcome from surgical operations and to reduce the ...

Powered prostheses can enable individuals with above-knee amputations to ascend stairs step-over-step. To accomplish this task, available stair ascent controllers impose a predefined joint impedance behavior or follow a preprogramed position trajectory ...

Total Knee Arthroplasty for Chronic Anterior Knee Dislocation
Background: The occurrence of chronic knee dislocation is rare. To the best of our knowledge, total knee arthroplasty for treatment of chronic anterior knee dislocation has not been reported. Method: This report describes 3 cases of chronic anterior knee

Biomechanics of the through-knee prosthesis [PDF]
The biomechanics of the through-knee prosthesis is considered in detail and comparisons made with the above-knee case. Socket shape and suspension are discussed and comment offered on knee function in both stance and swing phases.

Bouncy Knee in a Semi-Automatic Knee Lock Prosthesis [PDF]
The Bouncy Knee concept has previously proved of value when fitted to stabilised knee units of active amputees. The stance phase flex-extend action afforded by a Bouncy Knee increased the symmetry of gait and also gave better tolerance to slopes and uneven ground.

Design and Control of a New Biomimetic Transfemoral Knee Prosthesis Using an Echo-Control Scheme
Passive knee prostheses require a significant amount of additional metabolic energy to carry out a gait cycle, therefore affecting the natural human walk performance.

Estimation of Loosening of Knee Joint Prosthesis [PDF]
Knee replacement arthroplasty is indicated for the patient with advanced knee pain, knee deformation, and knee functional disorder. The aim of this study was to estimate loosening after a knee replacement arthroplasty.
