Development and Analysis of 3D-Printed Knee Orthosis for Post-Anterior Cruciate Ligament Injuries Rehabilitation

Year: 2024

Type: conference-paper

Abstract: An anterior cruciate ligament (ACL) rupture is one of the most severe injuries an athlete can suffer, resulting in knee joint instability and significant pain.This study aims to develop and analyze 3D-printed knee orthoses for post-ACL injury rehabilitation to overcome conventional orthoses' drawbacks.The project uses 3D scanning, modeling, and printing techniques.It evaluates knee orthoses performance of three different thicknesses and designs through finite element analysis using Marc software, focusing on von Mises stress and displacement.For the compression test, a face load is applied to the knee model's top surface, consisting of half the subject's body weight multiplied by 10 N. For the 3point bending test, a point load of 134 N is applied to the tibia's posterior part.Results show that a 7 mm thickness is optimal, exhibiting the lowest stress and displacement, providing the best support.
