Revision of the Gunston polycentric knee arthroplasty with total knee arthroplasty

Acta Orthopaedica et Traumatologica Turcica, 2020
The Gunston polycentric knee arthroplasty, first designed and performed by Frank Gunston in 1971, is the first prosthesis considering the natural knee biomechanics. Although the polycentric knee arthroplasty showed encouraging results to relieve pain and

Morphology characters of resected femoral and tibial surface in chinese population: intraoperative anthropometric study in patients at a tertiary hospital

BMC Surgery, 2022
Backgrounds Mismatch between knee surface and prosthesis components is related to postoperative complications. Morphological differences between ethnicity and gender may affect prosthesis coverage.

Formation of buckling resistance in a transfemoral prosthesis

Вестник медицинского института «Реавиз»: Реабилитация, врач и здоровье, 2022
Introduction. The principles of construction of the knee joint in the transfemoral prosthesis are considered. The design of the knee joint in the transfemoral prosthesis with an original mechanism for ensuring buckling resistance in the prosthesis is ...

Effect of Increasing Assistance From a Powered Prosthesis on Weight-Bearing Symmetry, Effort, and Speed During Stand-Up in Individuals With Above-Knee Amputation

IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2023
After above-knee amputation, the missing biological knee and ankle are commonly replaced with a passive prosthesis, which cannot provide net-positive energy to assist the user.

Modeling and Control of Knee-Ankle-Toe Active Transfemoral Prosthesis

IEEE Access, 2020
The main joints of lower limb are hip, knee, ankle, and toe. Because of accidents or diseases, some people have to amputate. Wearing prosthesis can help them return to normal life.

Effects of Prosthesis Mass on Hip Energetics, Prosthetic Knee Torque, and Prosthetic Knee Stiffness and Damping Parameters Required for Transfemoral Amputees to Walk With Normative Kinematics [PDF]

, 2014
We quantify how the hip energetics and knee torque required for an above-knee prosthesis user to walk with the kinematics of able-bodied humans vary with the inertial properties of the prosthesis. We also select and optimize passive mechanical components
