In collaboration with his research team, clinical colleagues and the orthopaedic industry, Professor Murray has developed the Oxford Partial Knee. This device has a mobile bearing, is implanted using a minimally invasive approach and is the most widely used partial knee replacement. The success of this development has led to a worldwide increase in the use of partial knees, mobile bearings and minimally invasive approaches.

He is a member of the hospital's joint replacement team, specialising in knee and hip joints, and also leads a team of clinical scientists who work with the Department of Engineering Science and with Professor Ray Fitzpatrick's group in the Institute of Health Sciences.

His team are undertaking biomechanical and clinical studies related to the knee and hip. The biomechanical studies use anatomical, computer modelling, gait analysis and x-ray techniques to study normal, diseased and replaced joints.

They have made major contributions to the understanding of knee kinematics, both in normal and replaced joints, and to the development of methods to predict and prevent failure in joint replacements.
