My research focuses on the investigation of ischaemic preconditioning as a potential therapeutic strategy for the improving patient outcome in orthopaedic surgical patients. Ischaemic preconditioning refers to the phenomenon whereby exposure of a tissue to a brief period of sub-lethal ischaemia results in protection against a subsequent prolonged period of ischaemia. It has been shown to protect against ischaemia-reperfusion injury in a number of clinical settings, and has been widely studied in cardiac surgery with increasing investigation in the areas of vascular surgery, acute kidney injury, stroke and transplant surgery. This technique may also have potential in orthopaedic surgery, for example in extremity surgery involving the use of a tourniquet. Therapeutic benefits for orthopaedic patients may include reduced post-operative pain, reduced systemic inflammation and oxidative stress, and improved functional outcome following surgery.
I am currently involved in a prospective randomised controlled study of ischaemic preconditioning in total knee replacement patients. This study aims to investigate if ischaemic preconditioning can improve clinical outcome in this cohort of patients. My work also focuses on the role of reactive oxygen species and oxidative stress in the molecular mechanism of ischaemic preconditioning; this work is conducted using tissue samples taken from control and preconditioned knee replacement patients, and is complemented by in vitro models of ischaemic preconditioning using skeletal muscle myotubes.
Other research interests include the investigation of statins as a potential therapy for osteoarthritis, and the effect of agents such as local anaesthetics and contrast media on cartilage integrity.
