Design and Development of Custom Knee Replacement Implant for Osteoarthritis Patients to Support Bone Fracture

Personalized Prosthesis Design Based on Patient Anatomy and Fracture Support Needs

Abstract

Due to the rising number of osteoarthritis patients at Hospital Tengku Fauziah, there is a need to improve knee transplant designs. Current issues include excessive design choices, allergic reactions to materials, and limited implant lifespan (up to 20 years). This study aimed to develop a new knee transplant design compatible with various patient conditions and using hypoallergenic materials. The design process involved interviews, benchmarking, and tools like the house of quality and morphological charts. A final concept was developed, modeled in 3D, and analyzed using finite element analysis (FEA), which confirmed strong structural integrity with a high Factor of Safety (FOS) of 155.005
