Overview

Jonathan Evans completed his undergraduate medical training at the University of Nottingham in 2006. He completed Foundation Training at the Ministry of Defence Hospitals Unit at Derriford Hospital, Plymouth before spending four years working as a General Duties Medical Officer in the Royal Navy. During this time, he deployed as a front-line doctor with the Royal Marines in Afghanistan as well as conducting anti-piracy operations in the Somali Basin on HMS LANCASTER. On return from Afghanistan, he completed his Core Surgical Training in Exeter; during which time he was awarded the Health Service Journal’s “Rising Star” prize for setting up and running the RD&E Quality Improvement Academy.

After leaving the Royal Navy, he completed his Higher Surgical Training on the South-West Peninsula rotation, before undertaking the Exeter Hip Fellowship between 2022 and 2023. He took time out of clinical training between 2017 and 2019 to work as the National Joint Registry Research Fellow, during which time he completed a doctorate at the University of Bristol as well as an MSc in Epidemiology from the London School of Hygiene and Tropical Medicine. His notable research works include articles in The Lancet (How long does a hip replacement last?, How long does a knee replacement last?), PLOS Medicine and The Lancet Rheumatology.

In 2022, he was appointed as a Clinical Senior Lecturer in Trauma & Orthopaedics at the University of Exeter and Consultant hip surgeon at the Exeter Hip Unit and started this role in 2023. He remains on the data analysis team of the NJR at the University of Bristol and as a Clinical Fellow of the National Hip Fracture Database. His main research interest is the management of periprosthetic femoral fractures.

Research

Research interests

Jonathan’s research interests to date have focused around the use of National Joint Registry data on long term outcomes following hip and knee replacement surgery. He has recently completed a grant (funded by Orthopaedic Research UK) investigating the epidemiology of Postoperative Periprosthetic Femoral Fractures (POPFF) using a linked NJR and Hospital Episode Statistics database. He is currently working on a project defining a Core Outcome Set for POPFF as well as working with a team from Imperial College London on the PROFOUND study (investigating pathways of care in POPFF).

Jonathan is the UK lead for a multinational trial into the management of Prosthetic Joint Infection (ROADMap) as well as a collaborator on an NIHR programme grant (HIPPY) investigating the survival outcomes of cemented, cementless and hybrid total hip replacements.
