Disclosures
I want you to know exactly who I work with and who pays for what, so you can judge my advice for yourself. This page lists every link I have with companies and organisations.
Implant and device companies
| Company | What I do | Who is paid |
|---|---|---|
| DePuy Synthes | Teaching other surgeons on courses; research funding, including a project on the Actis hip stem; a laboratory study of a collar on a hip stem, which DePuy Synthes supports and the Wrightington, Wigan and Leigh NHS trust sponsors; co-supervision of a PhD studentship at the University of Leeds that DePuy Synthes part-funds; speaker in a British Hip Society symposium supported by DePuy Synthes (March 2026, on a collar on some hip stems); the VELYS knee robot I use is theirs | The University of Bristol |
| Link UK | Teaching other surgeons on courses | The University of Bristol, not me personally |
| Smith+Nephew | Speaker at an industry symposium (Fragility Fracture Network, Edinburgh, October 2026); guest on their Joint Decisions podcast (September 2026); speaker at a Smith+Nephew educational meeting (July 2026) | The University of Bristol, not me personally |
I do not receive any payment, commission or reward from any company that depends on which implant I use. I choose implants for each patient on the published evidence, as explained in how I work.
The knee robot I use (VELYS) is made by DePuy Synthes, a company that funds some of my research and whose courses I teach on. It pays me nothing for using it.
Research funding and roles
- Research funding: AO UK, DePuy Synthes and the John Charnley Trust (which funded my PhD).
- National Joint Registry: I am a Lot 2 contractor (analysis of collected data and research) through the University of Bristol.
- University of Bristol: Consultant Senior Clinical Lecturer.
Independent records
My hip and knee activity and outcomes are published independently on my National Joint Registry surgeon profile.
Payments from pharmaceutical companies to doctors are published on Disclosure UK. Disclosure UK lists payments from medicine companies only. There is no single public list for implant and device companies, so I list my links here. I keep this page up to date; it was last updated in October 2026.
