Atraumatic patellar prosthesis dislocation with patellar tendon injury following a total knee arthroplasty: a case report [PDF]

Journal of Medical Case Reports, 2010
Introduction Total knee arthroplasty is a well-established procedure with gratifying results. There is no consensus in the literature whether to routinely resurface the patella while performing total knee arthroplasty or not.

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 Biotechnology
Background: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.

Development of a Passive Knee Motion Simulator to Evaluate Deep Knee Flexion of Total Knee 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

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 ...

Intraoperative sensor technology quantifies inter-prosthesis pressure for predicting lower limb alignment after Oxford unicompartmental knee arthroplasty

Frontiers in Bioengineering and Biotechnology, 2023
Purpose: The aim of this study is to quantify inter-prosthetic pressures at different knee angles in Oxford unicompartmental knee arthroplasty (OUKA) and its correlation with postoperative lower limb alignment.Methods: This study included 101 patients ...

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.

A lightweight robotic leg prosthesis replicating the biomechanics of the knee, ankle, and toe joint

Science Robotics, 2022
Robotic leg prostheses promise to improve the mobility and quality of life of millions of individuals with lower-limb amputations by imitating the biomechanics of the missing biological leg. Unfortunately, existing powered prostheses are much heavier and
