As a surgeon specialising in hip and knee replacements, Dan Williams aims to help people understand what causes joint pain, and how to prevent surgery by staying healthy.

Over 13 years of experience as a Trauma and Orthopaedic Consultant Surgeon, with a specialist interest in Primary and Revision Hip & Knee Replacement. Mr Williams's medical device review work follows journal and national review work, and a master’s degree thesis that forms part of a strong portfolio of published research.
