Conditions
Brief summary
The objective of the study is to determine whether tourniquet use during total knee replacement results in superior intra-operative and post-operative outcomes when compared to not using a tourniquet. All participants will be undergoing total knee replacement for advanced osteoarthritis. Participants will be followed up for one year following surgery. Outcomes include knee extension strength, pain and analgesia requirements, self-reported physical function and quality of life, blood loss and replacement, surgeon satisfaction with the intra-operative visual field, operation and anaesthetic time, tourniquet inflation time, complications including revision surgery, cement mantle quality, patient satisfaction, and hospital length of stay.
Interventions
All participants are undergoing total knee replacement. Orthopaedic surgeons will complete each knee replacement, with training registrars operating under direct supervision. Each operation will last approximately 2 hours. The tourniquet will be used for the duration of the procedure and deflated immediately prior to wound closure. Participants in the tourniquet group will have a tourniquet applied during surgery. After exsanguination of the operated limb with a rubber tube exsanguinator, the tourniquet will be inflated to 100mmHg above systolic blood pressure or 250mmHg, whichever is higher. Adherence to the intervention protocol will be monitored by the principal investigator (orthopaedic surgeon) and research coordinator.
