Overarching Research Aim

Alister Hart’s surgical and research interests focus on the achievement of the best possible patient and clinical outcomes after hip replacement, through implant design, surgical positioning and patient factors.

Current Rosetrees Research Project Detail

We will create state-of-the-art, true-to-life training for surgeons to practice hip replacement surgery.

Hip replacement is a common treatment for arthritic hip joints (80,000 per annum in the UK) and revision hip replacement has doubled in the last 5 years (10,000 per annum in the UK in 2012). With increasing population and life expectancy, the number of  hip replacement operations (both primary and revision surgery) is predicted to increase. Primary hip replacement operations will almost triple by 2030.  It is known that surgical training using a surgical simulation method can improve patients outcome after primary and revision hip replacement and reduce the number of redo / revision hip replacements. However, the delivery of surgical simulation can be costly and time consuming. Clinically relevant and cost-effective learning in the area of hip replacement is needed and would have an impact on a large number of patients and the NHS.  We aim to create innovative, practical and cost-effective training for surgeons to improve the clinical outcome for patients undergoing hip surgery.  Beyond this study courses will be run at multiple sites for speedy and more effective dissemination and to maximise the number of surgeons and patients to be benefited from the technology.

Summary of Researcher Background

Alister Hart is head of clinical research in orthopaedics at UCL and the director of research and development at the Royal National Orthopaedic Hospital (RNOH). He studied medicine at Caius College Cambridge (q 1994), did basic surgical training at Guy’s and St Thomas’ Hospitals and higher surgical training on the RNOH rotation. In 2006 he was appointed Clinical Senior Lecturer and Consultant Orthopaedic Surgeon at Imperial College London and in 2012 to the present position.

His research interest on the performance of orthopaedic implants is complemented by his clinical practice as a hip and knee implant surgeon: he has performed more than 3000 operations including 900 revision hip and knee replacements.

He is a co-director, with John Skinner, of the London Implant Retrieval Centre. He teaches on aspects of hip surgery to surgeons of all grades, including orthopaedic basic sciences, patient assessment using clinical examination and imaging, patient management and surgical technique.
