Simon Ellis: Profile

Mr Simon Ellis is a leading Consultant Knee Surgeon with his practice based at the Kent Institute of Medicine and Surgery (KIMS) in Maidstone, Spire Alexandra Hospital in Walderslade and the One Ashford Hospital in Ashford, Kent. With over 20 years’ experience in the field and an approach based on excellent communication, he provides rapid access to treatment for the full range of knee problems affecting adults and young people aged 12-18.

Training and experience

Mr Simon Ellis studied medicine at St John’s College Cambridge, where he studied medical ethics and law as his final year elective.  He completed his clinical studies at Charing Cross Hospital in London, gaining his medical degree in 1985 followed by a Master of Arts degree in 1988.

Having obtained his surgical fellowship, Simon went on to undertake specialist orthopaedic training that included 15 months at Lord Mayor Treloar Hospital, a specialist orthopaedic hospital, under the supervision of Neil Thomas, past president of the Knee Society, and a two-year appointment as senior registrar at the Royal United Hospital in Bath.

Simon was appointed as a general trauma and orthopaedic surgeon to Maidstone and Tunbridge Wells NHS Trust in 1996, however over time, his interests led him to make the conscious decision to specialise exclusively in knee surgery. Since leaving the trust in 2016, he has continued in independent knee practice seeing private patients who are insured or self-funding, as well as those referred by their general practitioner through the NHS referral scheme.

Simon is regularly approached to lecture to general practitioners and allied health professionals on matters related to knee surgery. He is a member of the British Orthopaedic Association (BOA), the British Association of Surgery for the Knee (BASK)  as well as the South East Knee Study Group who meet regularly to exchange views on difficult cases.


Simon recognises that the key to successful treatment is good communication. He is committed to listening, explaining knee problems in understandable terms and ensuring that patients have all the information they need to make their own management decisions. Ultimately, he has a very simple, but important mission statement:

“I give the same quality of care to my patients as I would want my family and friends to receive.”

Clinical interests

Simon’s clinical interests cover all aspects of knee surgery, including the treatment of knee sports injuries and knee arthritis. Over the years he has invested a considerable amount of time in the study of knee surgery, maintaining a keen interest in the development of soft tissue knee surgery.

Simon’s made the decision to concentrate solely on knee surgery early during his consultant career.  An invitation to the Stryker Arthroscopic International Forum and a tour of America, led him to explore the further possibilities of arthroscopic knee surgery and anterior cruciate ligament (ACL) reconstruction. He was responsible for introducing accelerated rehabilitation following ACL reconstruction in Kent and has lectured on ACL reconstruction at international meetings. As well as treating all ligament issues, he has a specialist expertise in meniscal problems.

Simon provides a full range of treatment options for knee arthritis, from conservative measures to partial and total knee replacement surgery following the latest guidelines on the enhanced recovery programme. In particular, he has pioneered the implementation of the Depuy Attune knee replacement in Kent, a newer replacement now with over 5 years outcome data suggesting an improvement in patient satisfaction.

Committed to staying abreast of all the latest developments in knee surgery, Simon attends both national and international specialty meetings.
