Design and Speed-Adaptive Control of a Powered Geared Five-Bar Prosthetic Knee Using BP Neural Network Gait Recognition.
Sensors (Basel, Switzerland)
Oct 27, 2019
To improve the multi-speed adaptability of the powered prosthetic knee, this paper presented a speed-adaptive neural network control based on a powered geared five-bar (GFB) prosthetic knee. The GFB prosthetic knee is actuated via a cylindrical cam-b...
Comparison between navigated reported position and postoperative computed tomography to evaluate accuracy in a robotic navigation system in total knee arthroplasty.
The Knee
Jun 4, 2019
BACKGROUND: Computer navigation increases reproducibility compared to non-navigated total knee arthroplasty (TKA). Robotics navigation is a branch of computer navigation technology that might further improve accuracy of implant placement. The aim of ...
Economic benefits of microprocessor controlled prosthetic knees: a modeling study.
Journal of neuroengineering and rehabilitation
Sep 5, 2018
BACKGROUND: Advanced prosthetic knees allow for more dynamic movements and improved quality of life, but payers have recently started questioning their value. To answer this question, the differential clinical outcomes and cost of microprocessor-cont...
How Much Does the Anatomical Tibial Component Improve the Bony Coverage in Total Knee Arthroplasty?
The Journal of arthroplasty
Dec 27, 2016
BACKGROUND: Recently, anatomical designs in total knee arthroplasty are introduced to address asymmetry of the resected tibia cutting surface. It is still not well known how much improvement would be achieved in total knee arthroplasty, especially in...
Impact on gait biomechanics of using an active variable impedance prosthetic knee.
Journal of neuroengineering and rehabilitation
Jun 10, 2016
BACKGROUND: An above knee amputation can have a significant impact on gait, with substantial deviations in inter-leg symmetry, step length, hip exertion and upper body involvement even when using a current clinical standard of care prosthesis. These ...
Quantitative Analysis of Technological Innovation in Knee Arthroplasty: Using Patent and Publication Metrics to Identify Developments and Trends.
The Journal of arthroplasty
Dec 20, 2015
BACKGROUND: Surgery is in a constant continuum of innovation with refinement of technique and instrumentation. Arthroplasty surgery potentially represents an area with highly innovative process. This study highlights key area of innovation in knee ar...
Surrogate modeling of deformable joint contact using artificial neural networks.
Medical engineering & physics
Jul 26, 2015
Deformable joint contact models can be used to estimate loading conditions for cartilage-cartilage, implant-implant, human-orthotic, and foot-ground interactions. However, contact evaluations are often so expensive computationally that they can be pr...
Application of artificial intelligence in X-ray imaging analysis for knee arthroplasty: A systematic review.
PloS one
Jan 1, 2025
BACKGROUND: Artificial intelligence (AI) is a promising and powerful technology with increasing use in orthopedics. The global morbidity of knee arthroplasty is expanding. This study investigated the use of AI algorithms to review radiographs of knee...
[Research progress of functional alignment robot assisted knee replacement].
Zhongguo gu shang = China journal of orthopaedics and traumatology
Nov 25, 2023
The correct alignment of the knee joint is considered to be one of the most influential factors in determining the long-term prognosis after total knee arthroplasty(TKA). In order to achieve the correct alignment goal, many different alignment concep...
[A multicenter randomized controlled trial of domestic robot-assisted and conventional total knee arthroplasty].
Zhongguo xiu fu chong jian wai ke za zhi = Zhongguo xiufu chongjian waike zazhi = Chinese journal of reparative and reconstructive surgery
Nov 15, 2023
OBJECTIVE: To investigate the accuracy, safety, and short-term effectiveness of a domestic robot-assisted system in total knee arthroplasty (TKA) by a multicenter randomized controlled trial.
