Biomechanically-Informed Design of Prosthetic Sockets for Transfemoral Amputees Using Anatomical Relational Parameters and Finite Element Analysis

Year: 2026

Type: conference-paper

Abstract: Prosthetic socket design for lower-limb amputees has traditionally focused on optimizing surface pressure distribution, but emerging research highlights the need to consider other factors to prevent pressure ulcers and deep tissue injuries (DTI), as well as maximize metabolic efficiency. This study explores the possibility of incorporating amputee-specific anatomical conditions, referred to as relational parameters, into the finite element analysis (FEA)-based design of prosthetic sockets. This is done through the case-study of a knee disarticulation (KD) patient with a non-union femur. The results show that different socket designs (quadrilateral, ischial confinement (IC), and KD) influence the alignment and stress reduction of the femur differently, offering trade-offs between metabolic efficiency, comfort, and risk of injury. These findings provide a framework on how to design amputee-specific prosthetic sockets for enhanced patient outcomes.
