Intervention / Treatment
Detailed Description
A total of 80 patients who will undergo total knee arthroplasty will be randomized into two groups:
Treatment groups Treatment details Femoral Group (40 patients) Continuous femoral nerve block (bolus: 0.5% Ropivacaine 10-15 ml ; infusion of 0.15 % Ropivacaine 4-6ml/h) Adductor Group (40 patients) Adductor canal block with steroid adjuvant (bolus: 0.5% Ropivacaine 10-15ml; Dexamethasone 4mg) (Total 80 patients will be recruited)
- All patients will receive single shot tibial nerve block with local anaesthetics (0.5% Ropivacaine 5-8ml) before surgery for analgesia of posterior knee.
- All patients will receive the same preemptive and postoperative multimodal medications for perioperative analgesia.
- All groups will receive standardized method of spinal anaesthesia and standardized method of intraoperative sedation for the surgery.
- Intravenous patient controlled analgesia (PCA) with morphine will be given for 48h to patient as rescue analgesia.
