ISTA 2025 - A Hip Joint Replacement Design with a Wear Particle Control System

Description

This presentation from the ISTA 2025 conference held in Rome, outlines a groundbreaking project focused on designing a hip joint replacement that incorporates a wear particle control system. It aims to address significant issues inherent in traditional hip replacements, specifically the wear particles generated during movement between the femoral head and plastic liner. With over 100,000 hip replacements performed annually in the UK and concerns regarding longevity and complications leading to revision surgeries, the proposed solution seeks to enhance patient outcomes by effectively managing wear debris.



The innovation consists of a fluid pathway integrated into the implant design that guides wear particles away from sensitive tissues, employing a microtexture pattern to trap particles. Detailed testing methods, including finite element analysis and computational fluid dynamics, emphasize the concept's viability under various loading conditions. Results indicate a promising reduction in wear particles, potential longevity improvements, and a substantial reduction in revision surgeries. Ultimately, this innovative approach not only aims to improve patient quality of life but also significantly reduce healthcare costs and labor associated with revision surgeries.
