This module will provide an insight into the engineering based problems faced in orthopaedic biomechanics, through a detailed study of intact lower limb and the lower limb pre- and post- total joint replacement. You will gain an understanding of the structure of bone from the micro scale through to the full construct level, the major bones and tissues in the lower limb, their structure property relationships, and their kinematics. This knowledge will underpin your understanding of the replaced joint and its function, from an engineering perspective and from a surgical perspective. Finally, you will learn about the modes of failure of the replaced joint, and what can be done to prevent failure based on clinical experience, materials selection and design.
Aims and Objectives

This is how we’ll formally assess what you have learned in this module.
This is how we’ll assess you if you don’t meet the criteria to pass this module.
An internal repeat is where you take all of your modules again, including any you passed. An external repeat is where you only re-take the modules you failed.
Repeat type: Internal & External
