简要总结
Total knee arthroplasty or replacement (TKA), a commonly performed surgery for osteoarthritis of the knee, is a painful procedure and requires a multimodal analgesic approach. A method for analgesia is local infiltration analgesia (LIA), where a mixture of drugs is injected around the knee joint.
Adductor canal block (ACB) is an alternative regional anaesthesia technique which has been shown to result in minimal thigh weakness.
The investigators aim to study if the analgesia provided by ACB is superior to LIA while preserving quadriceps strength.

排除标准
- •Patients unable to give consent, inability to communicate/ cooperate, patients with regular consumption of strong opioids (morphine, oxycodone) or steroids, allergy to local anaesthetics or any drugs included in the study, patients with lower limb surgery in the preceding year, patients with pre-existing neurological deficits and patients who have contraindications for spinal anaesthesia.
研究组 & 干预措施
Local Infiltration Analgesia
The Local Infiltration Analgesia group will receive local infiltration of ropivacaine 150mg, ketorolac 30mg, morphine 10mg, adrenaline 200mcg and vancomycin 500mg in a total volume of 75mls by the surgeon.
Adductor Canal Block
The Adductor Canal Block group of patients will receive intravenous ketorolac 30mg intra-operatively and an adductor canal block at the end of surgery. The block will be performed under real time ultrasound guidance and 30mls of 0.5% ropivacaine (150mg) is injected with a Stimuplex A100, 21G needle.
干预措施: Adductor Canal Block (Procedure)
