A word from Professor Bill Walter about commercial business arrangements:

I am often approached by companies who request my services to assist with product development, as are other leading orthopaedic surgeons from other countries. I have been involved with many product development projects over the last 10 years.  I have also written and been granted several patents in the field of orthopaedic surgery and I will continue to innovate and improve my field. Surgeons are critical to the development process for orthopaedic implants, instruments and techniques.

It is not possible for the engineers working for the orthopaedic manufacturers to design them well without knowledgeable, meticulous, ethical, practising surgeons involved.  No-one is better placed to innovate in orthopaedics than a surgeon with intimate knowledge and experience of the surgery and the effect it has on patients.  I am a surgeon, a meticulous researcher and I have a PhD (with a particular focus in the biomechanics of joint replacement). Thus I am a vital contributor to the development process. I thoroughly enjoy being involved in design development, as it is challenging, interesting and professionally rewarding and ultimately provides benefits to patients in many countries around the world.

I am paid for the work I do with these multinational companies, and I consider my time and knowledge to be of value and I expect to be remunerated for my contribution.  In some cases where I have contributed intellectual property, I receive royalties on products. These days, in order to protect the interests of patients, companies are governed by very strict rules about how they engage with surgeons in business. My patients should be aware that I do not receive payments or royalties or incentives of any kind to use a particular implant for their surgery. My highest priority is always my duty of care to my patients.

My decision to use any given implant in a patient is governed completely by the clinical decision making process. I use the implant which, in my professional medical opinion, is going to deliver the best possible result for the patient.  My second highest priority is research and science.  The third highest priority for me is any commercial arrangement that I may have to do with product development.  My professional integrity is of utmost importance and is something that I have thought about deeply and I take very seriously.
