Analgesic efficacy of subcutaneous local anaesthetic wound infiltration in bilateral knee arthroplasty: a randomised, placebo‐controlled, double‐blind trial

Abstract

As part of a total wound infiltration analgesia intraoperative subcutaneous infiltration with ropivacaine in bilateral total knee arthroplasty is effective in early post-operative pain management, while a post-operative subcutaneous bolus administration through a multiholed catheter 24 h post-operatively did not show improved analgesia compared with the administration of saline.
