Summary
Brief summary
Participation will involve being randomly assigned to one of two routinely used pain management protocols to provide pain relief in the period immediately after total knee replacement surgery. Participants will be unaware as to which group they are in. A pain specialist doctor and nurse will assess pain control and range of movement of the knee at regular intervals following the surgery. This will assist surgeons and anaesthetists to determine the most effective regimen for future patients.
