Matt Dawson is a Knee Surgeon who specialises in sports injuries and degenerative conditions affecting the knee. He is a leading authority on osteotomy and Joint Preservation surgery in the UK and Europe.

Having completed his Orthopaedic training in London and a Sports Knee Fellowship in Dublin, Mr Dawson joined North Cumbria University Hospital in 2001.

Mr Dawson performs a wide range of knee procedures including arthroscopy, femoral and tibial osteotomy, total and partial knee replacement, articular cartilage surgery, single and multiple ligament reconstruction, patella realignment and stabilisation and a range of combined complex procedures for deformity and instability. Mr Dawson has developed one of the largest UK practices in osteotomy with over 400 cases to date.

Mr Dawson believes in the principle of joint preservation in order to prolong knee activity and knee function to the highest level. His philosophy is to individually assess patients with the appreciation that alignment and stability of the knee are the bedrock to successful knee function and successful surgery.

Mr Dawson is committed to the education of healthcare professionals. He hosts a successful fellowship in Osteotomy and Knee surgery at North Cumbria University Hospital and lectures locally, nationally, and internationally. He has published in peer-reviewed journals on the subject of osteotomy. He is one of two UK members on the ESSKA osteotomy committee.

In June 2015 Mr Dawson launched the annual Northern Osteotomy Masterclass. This acclaimed course attracts experts from around the globe and provides high-quality training for consultants and the surgeons of tomorrow. He is a co-convenor of the Basingstoke Osteotomy Masterclass and founder member and committee member of UKKOR, the world’s first national osteotomy registry.

Mr Dawson is working at the leading edge of knee osteotomy surgery with device technologies, surgical applications, and teaching techniques. He is a driver in several research projects in the field. Currently Mr Dawson is collaborating with a leading American company and European colleagues with a groundbreaking technology aimed at increasing accuracy of osteotomy surgery. This innovative technology permits correction of alignment to occur under precise post-operative control using a magnetic remote control device. Mr Dawson is the first UK surgeon to perform this surgery.

Mr Dawson undertakes his NHS practice at the North Cumbria University Hospital and consults privately in Carlisle, at The Cumbrian Clinic, Whitehaven and at BMI Hospital in Lancaster.

David Elson is consultant orthopaedic surgeon at the Queen Elizabeth hospital in Gateshead. He was a trainee in the Northern Deanery and lives in Newcastle upon Tyne.

He completed knee surgery fellowships in both Cardiff and Hampshire and has worked for Matt Dawson, Chris Wilson, Mike Risebury and Adrian Wilson (all faculty members) which puts him in a unique position to comment on the results from these osteotomy centres.

He strongly believes that the techniques of knee osteotomy should be refined in light of patient outcomes and to this aim he has been driving the United Kingdom Knee Osteotomy Registry (www.ukkor.co.uk). This is an initiative designed to capture meaningful outcome data which should influence future surgical techniques in years to come.

He has several publications in the field of knee surgery and has presented at national and international conferences. He has aspirations to improve the message about knee osteotomy as a highly successful surgery.

Raghbir graduated from St George’s Hospital Medical School in 2006 and completed his higher surgical training in the South East London region.

Following his training, he went on to refine his skills in knee surgery with a fellowship under the tutelage of Professor Wilson, Mr Risebury and Mr Yasen. This fellowship allowed him to develop a keen interest in all aspects of osteotomy surgery, cartilage preservation, arthroscopic ligament reconstructions, partial and total knee arthroplasty surgery. He has a particular interest in managing arthritis in younger patients and is a Consultant in Knee Surgery at Guys and St Thomas’ Hospital London.

Raghbir has published in all aspects of knee surgery and presented both nationally and internationally. He is an honorary lecturer at Winchester University and runs educational courses for higher orthopaedic surgical trainees in London.

Kristian Kley completed his medical training at Hannover Medical School in 2006 and then started a residency in orthopaedic trauma in Hannover with Prof Philipp Lobenhoffer. He is now working as fellow in a group practice in Hannover (Gelenkchirurgie Orthopädie Hannover) with Prof. Lobenhoffer.

Kristian Kley early developed a strong interest in osteotomy around the knee. He is an active member of the Hannover team treating 300 patients per year with osteotomy around the knee and developing new techniques and instruments to ease these procedures.

He has been active on national and international meetings and is also guest member of the Joint Preservation Expert Group of AO Foundation. Kristian Kley has developed unique techniques of minimal-invasive osteotomy of femur and tibia which are now used clinically in Hannover on a regular basis.

Matthieu Ollivier is an associate professor of orthopaedic surgery at the Institute for Locomotion at Sainte Marguerite's Hospital and an assistant professor of anatomy at the Medical University in Marseille.
