Modifying the Design of the Oxford Domed Lateral Unicompartmental Knee Replacement Implant Reduces the Risk of Medial Bearing Dislocation

Description

In this presentation, Irene Yang, a PhD researcher from the University of Oxford, discusses her work on modifying the Oxford Domed Lateral unicompartmental knee replacement implant to reduce the risk of dislocation of the mobile bearing. She highlights the growing concern of lateral knee osteoarthritis, projected to affect millions in the near future, and the conventional treatment of unicompartmental knee replacement which retains native ligaments through a minimally invasive procedure. Irene details the implant's components, the clinical implications of bearing dislocation affecting 1% to 6% of patients, and her experimental approach using a custom mechanical rig to investigate dislocation mechanics during knee flexion. By leveraging principles from robotics and path planning algorithms, she developed a computational analysis tool that enables the design of modifications aimed at lowering dislocation rates. Following her conclusions, she engages in a dynamic question-and-answer session discussing potential challenges in surgical procedures and the implications of her work for future knee implant designs. This project aims to enhance patient outcomes by addressing the significant issue of dislocation in knee replacement surgeries.
