Anaesthesia for total knee arthroplasty: efficacy of single-injection or continuous lumbar plexus associated with sciatic nerve blocks–a randomized controlled study

Total knee arthroplasty (TKA) often results in marked postoperative pain. We compared in a randomized controlled study tramadol consumption, postoperative pain and patient satisfaction after primary TKA in patients who received a single injection lumbar plexus and sciatic nerve blocks or a continuous lumbar plexus and sciatic nerve blocks. Forty-four patients scheduled for unilateral total knee arthroplasty were allocated to the single shot group (group A) or to the catheter group (group B). All patients (in both groups) reported being satisfied with their anaesthetic management. Although pain scores and tramadol consumption appeared lower in the active infusion group, the differences did not reach statistical significance. This study confirms that either single injection or continuous infusion of Ropivacaine in lumbar plexus provides reliable and long-acting anaesthesia and analgesia
