The biomechanical effects of the inclusion of a torque absorber and type of knee units on trans-femoral amputee gait [PDF]
, 2002 This paper reports on a pilot study investigating the effects on the gait of two transfemoral amputees of to the inclusion of a torque absorber (TA) and its location relative to the knee unit.

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Purpose Modifying femoral morphology after total knee arthroplasty (TKA) poses a potential risk for ligament‐imbalances and patella mal‐tracking. The purpose of this study was primarily to quantify TKA‐induced stuffing around the femur and secondarily assess the effect of femoral rotation (FR) on trochlear and condylar anatomy‐changes ...

Viscoelasticity Estimation of Sports Prosthesis by Energy-minimizing Inverse Kinematics and Its Validation by Forward Dynamics [PDF]
Advanced Robotics, 2024, 1-13In this study, we present a method for estimating the viscoelasticity of a leaf-spring sports prosthesis using advanced energy minimizing inverse kinematics based on the Piece-wise Constant Strain (PCS) model to reconstruct the three-dimensional dynamic behavior.

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract Purpose The best fixation method for total knee arthroplasty (TKA) remains controversial. The aim of this study is to compare the effect of cemented and cementless fixation on prosthesis survivorship. Our primary hypothesis is that there is no difference in survivorship between cemented and cementless TKA.

Fracture of the tibial baseplate in bicompartmental knee arthroplasty [PDF]
, 2015 Introduction. Bicompartmental knee arthroplasty (BKA) addresses combined medial and patellofemoral compartment osteoarthritis, which is relatively common, and has been proposed as a bridge between unicompartmental and total knee arthroplasty (TKA).

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.Abstract The rising volume of primary hip and knee arthroplasties has led to a parallel increase in revision surgeries, creating significant clinical and economic challenges for healthcare systems worldwide. This study synthesizes national arthroplasty registry data to evaluate trends in revision aetiology, associated costs and regional disparities ...

Impedance Control of a Transfemoral Prosthesis using Continuously Varying Ankle Impedances and Multiple Equilibria [PDF]
arXiv, 2019 Impedance controllers are popularly used in the field of lower limb prostheses and exoskeleton development. Such controllers assume the joint to be a spring-damper system described by a discrete set of equilibria and impedance parameters. Said parameters are estimated via a least squares optimization that minimizes the difference between the controller'
