Randomized Controlled Trial Comparative Study
Pain control after primary total knee replacement. A prospective randomised controlled trial of local infiltration versus single shot femoral nerve block.
We report a prospective blinded randomised trial of local infiltration versus femoral nerve block in patients undergoing primary total knee replacement (TKR), in accordance with the CONSORT statement 2010. ⋯ Intraoperative local infiltration gives superior pain relief compared to single shot femoral nerve block over the first 24h following primary TKR and minimises post-operative opiate use.
