The lateral femoral cutaneous nerve (LFCN) is a purely sensory nerve from the lumbar plexus. We hypothesised that an LFCN block would reduce movement\u2010related pain after total hip arthroplasty (THA) in patients with moderate\u2010to\u2010severe pain.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Sixty patients with visual analogue scale (VAS) score &gt; 40 mm during 30\u2010degree active flexion of the hip on either the first or second postoperative day after THA were included in this prospective, randomised, blinded, placebo\u2010controlled trial. Group A received an LFCN block with 8 ml of 0.75% ropivacaine followed after 45 min by an additional LFCN block with 8 ml of saline.
