Abstract: A bulky compression dressing (the Robert Jones bandage) is often used by orthopaedic surgeons. We have reviewed its history and monitored intramuscular compartment pressure under it after total knee replacement. We found that it increased compartment pressure and helped to reduce bleeding, tissue oedema and the size of effusions and haemarthroses.
