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]

open access: yes, 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

GUEPAR hinge knee prosthesis

open access: yesOrthopaedics & Traumatology: Surgery & Research, 2014
Early and late results of the GUEPAR hinge knee prosthesis were evaluated on a series of 184 operations performed before January 1st, 1974. There were 3 immediate deaths and 26 before 5 years. Nineteen prostheses were removed. One hundred and twenty-six knees had degenerative osteoarthritis, 52 rheumatoid arthritis.

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

open access: yesIEEE 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.

The unstable knee prosthesis

open access: yesRevista Española de Cirugía Ortopédica y Traumatología (English Edition), 2009
Abstract Prosthetic instability is the third most frequent cause for the failure of total knee replacement (TKR), which leads to between 10% and 22% of surgical revisions. In addition to individual factors such as previous instabilities or deformities, an associated neuromuscular condition, rheumatoid arthritis or obesity, the main causes for ...

The mechanics of the knee and prosthesis design [PDF]

open access: yesThe Journal of Bone and Joint Surgery. British volume, 1978
The mechanisms controlling and limiting movement and serving to transmit load between the femur and the tibia are discussed. Having accounted for the transmission of all components of force and couple across the joint and noted the load-bearing role of the menisci, some principles which might guide the design of knee prostheses are deduced.

Two-stage Operations for Treating Floating Knee Periprosthetic Fractures: A Case Report and Literature Review

open access: yesFormosan Journal of Musculoskeletal Disorders, 2023
Periprosthetic fractures (PPFs) in total knee arthroplasty (TKA) are challenging for orthopedic surgeons. A floating knee injury around TKA, especially with component loosening, attributes more complexities in management for the joint reconstruction ...
