Zaid Hamoodi

Mr Zaid Hamoodi is a Trauma and Orthopaedics Specialty Registrar (ST8) in the Northwest (Mersey) Deanery with a specialist interest in upper limb surgery. He is a former NJR/RCSEng Research Fellow and a PhD candidate at the University of Manchester, where his research explores the predictors of failure in total elbow replacement.

He led the NJR Data Quality Audit (NJRDQA) for elbow arthroplasty alongside Professor Adam C Watts. This was a national collaborative initiative involving the NJR, BOTA, BOA, BESS, and RCSEng. This work improved the completeness and accuracy of elbow data within the registry, and involved engaging with orthopaedic trainees across the UK to drive meaningful improvements in national data quality.

Tim Wilton trained at Oxford and at UCH medical school and in Orthopaedics at Nottingham, Harlow Wood, Derby and South Wales with travelling fellowships in N America, Strasbourg, Bern and Ljubljana. He has an entirely elective practice in lower limb arthroplasty and has specialised in knee replacement and knee revision surgery for the last 30 years. He has a lifetime personal experience of over 2500 hip and 3500 knee replacements.

Tim teaches widely on technical aspects of knee replacement and has been invited lecturer throughout the world and at the major European, North American and International Knee Surgery organisations.

Tim has been President of the BOA and of BASK, and Chairman of the Bone and Joint Journal.

He is NJR Medical Director and Vice Chair, NJR Board.                                                                

Professor Michael Whitehouse

Professor of Trauma and Orthopaedics, University of Bristol

Mike is a Professor of Trauma and Orthopaedics at the University of Bristol. His research focuses on the treatment of osteoarthritis, outcomes of joint replacement, adverse events such as the treatment of PJI, hip fracture, open fractures and cartilage damage. He employs a wide range of research methodologies including multicentre randomised controlled trials, first-in-human trials, analysis of large routinely collected healthcare datasets, evidence synthesis, qualitative methods and health economics. He leads the NJR lot 2 contract for Statistical Analysis, Support and Associated Services and a range of NIHR funded studies investigating bearings in THR, optimisation for surgery, intra-articular injections, novel devices and treatments for cartilage damage and infection. Mike has published over 250 peer reviewed papers, 9 NJR annual reports, and obtained grant funding of £5.9 million as lead and a further £16.4 million as co-applicant. He sits on the British Orthopaedic Association and British Hip Society research committees.

Derek Pegg

Consultant Trauma and Orthopaedic Surgeon, Mid Cheshire Hospitals Foundation Trust, Chair, NJR Data Quality Committee

Derek Pegg is a Consultant Trauma and Orthopaedic Surgeon at Leighton Hospital, Mid Cheshire Hospitals Foundation Trust, Crewe. Appointed in 1996, Derek developed a specialist interest in both hip and knee replacement surgery and (until very recently) their revision. He joined the NJR as a regional clinical coordinator (RCC) for the Northwest in 2012, becoming the deputy chair in 2017 and was appointed Chair of the RCC Committee in January 2021. He is also a member of the NJR Board, Executive Committee and Chair of the NJR Data Quality Committee.

Mark Wilkinson

Professor of Orthopaedics, Sheffield Teaching Hospitals, Chair, NJR Research Committee

Professor Wilkinson's principal research interests are in the genetic and metabolic aspects of joint replacement, osteoarthritis, and other associated diseases. Professor Wilkinson is a key clinical collaborator in the Genetics of Osteoarthritis initiative. He and his collaborators have been instrumental in determining our current understanding of the genetic architecture of osteoarthritis. He conducted the first genome-wide scan into hip dysplasia, and into osteolysis and heterotopic ossification after hip replacement, He published the first study in humans to show that bisphosphonates may suppress bone loss after hip replacement and the first clinical trial to show that the human monoclonal antibody denosumab can inhibit osteolysis lesion activity. Other areas of research include exploration of the molecular mechanisms that underpin osteoarthritis development and identifying potential novel pharmacological strategies for its treatment. He has worked on the genetics of osteoarthritis has uncovered novel gene associations with severity and pattern of hip and knee OA, bone remodelling responses to disease, and hip shape. He also studied the systemic health effects of metal ion exposure after hip resurfacing has demonstrated effects on bone cells, cardiovascular, and other systems.

Professor Wilkinson’s principal funding sources are Versus Arthritis, NIHR, Wellcome, MRC, Royal College of Surgeons of England, Cavendish Foundation, John Charnley Trust and industry.

Valsamis Markos

Markos completed his medical studies at the University of Cambridge and entered specialty training in Trauma and Orthopaedics in Oxford. His DPhil at the University of Oxford was titled “Improving outcomes for patients having shoulder replacements: guiding patient selection, evaluating cost-effectiveness and informing NHS provision” and was funded by an NIHR Doctoral Fellowship.
