He is dedicated to improving patient outcomes, through his use of the UK National Ligament Registry (UKNLR), the UK Osteotomy Registry (UKKOR), the UK Joint Registry (UKNJR), and collects his own outcome data for arthroplasty and multi-ligament knee surgery. He aims to integrate, and improve upon, the evidence-based treatment methods from International knee and trauma conferences.
