Recruitment & Eligibility

• Status: Completed
• Sex: All
• Target Recruitment: 104

Inclusion Criteria

1. All patients over the age of 18 undergoing total knee replacement (TKR) at the Addenbrookes NHS Trust
2. American Society of Anesthesiologists (ASA) physical status I - III

Exclusion Criteria

1. ASA IV and V
2. Age: less than 18 years old. There is no upper limit
3. Inability to use a PCA (Dementia, psychiatric problems, intellectual disability). A morphine PCA is the best way to monitor the use of morphine in the study.
4. Contraindication to non-steroidal anti-inflammatory (NSAIDs) (asthmatics with significant sensitivity to aspirin, renal impairment, severe liver dysfunction, history of gastric ulceration or bleeding). NSAIDs are a useful adjunct to pain relief and are necessary to be prescribed in the study.
5. Opioid dependence or chronic pain syndromes. The morphine use in this group would be difficult to interpret and may skew the data.
6. Contraindication to neuro-axial blockade or regional techniques; bleeding diathesis, anti-coagulation, absolute LA allergy, localized infection or relative contraindications of concurrent peripheral neuropathy or nerve injury.
7. Use concurrently of any other regional technique (such as spinal anaesthesia, epidural). These would interfere with the primary aim, that is, we are comparing nerve blocks not in conjunction with spinal or epidural anesthesia.
