Professor Ashley Blom is the Head of the Department of Translational Health Sciences and is one of the University's 12 NIHR Senior Investigators. 

He leads the analysis team of the National Joint Registry for England, Wales, Northern Ireland and the Isle of Man (NJR), which is the largest registry of joint replacements in the world. In addition to NJR research into the outcomes of arthroplasty, he leads major NIHR funded programmes into treating infection after arthroplasty; improving the patient experience of joint replacement; first-in-human studies of meniscal repair (including stem cell therapy) and biofunctionalisation of titanium. He leads the Orthopaedic workstreams into Surgical Innovation in the University of Bristol Biomedical Research Centre.

Professor Blom is currently the President of the European Orthopaedic Research Society and is member of both the Education and Specialist Societies Committees of the European Federation of National Associations of Orthopaedics and Traumatology. 

Activities / Findings

Ashley and the team in the Musculoskeletal Research Unit have published seminal work on the safety and efficacy of Orthopaedic implants. This work includes papers published in the Lancet showing the catastrophically high failure rates of metal-on-metal and resurfacing hip replacements and showing which factors are associated with decreasing mortality after hip and knee replacement. The team are currently undertaking a large body of research into infection and have published work showing which factors are associated with an increased risk of infection after joint replacement. Ongoing work includes a multinational trial of one versus two stage revision for infected hip replacements and analysis of the NJR to determine the relative efficacy of different treatment strategies for infection after hip and knee replacement.

The team have recently completed a first-in-human study using stem cells to heal meniscal tears in the knee.

I studied Medicine in Cape Town graduating in 1991. In 1994 I emigrated to the UK and undertook postgraduate training as an Orthopaedic Surgeon in Bristol, being made a Fellow of the Royal College of Surgeons of England in 1997, and receiving a Fellowship in Orthopaedics and Trauma Surgery in 2003. I received a PhD in 2003 for work on artificial bone graft substitutes and a MD in 2006, for work on preventing wound infection in joint replacement surgery, both from the University of Bristol. In May 2007 I succeeded Professor Learmonth as Head of the Orthopaedic Group of the University of Bristol and in October 2007 I became the chairman of the North Bristol Trust Research Committee. My research interests include outcomes of arthroplasty, the safety of Orthopaedic implants and restitution of bone stock loss.
