In plain words

What the trial is, and whether it could suit you

Total hip arthroplasty (THA) is a common surgery to replace damaged hip joints, but many patients experience significant pain after surgery, which can delay recovery and increase the need for strong pain medications (opioids). Nerve blocks are a technique where anesthetic medication is injected near specific nerves to reduce pain. This study compares two different ultrasound-guided nerve block techniques for pain control after THA: the QLESP block (a newer technique that targets two areas with a single injection) and the PENG block combined with the LFCN block (a currently used technique that targets nerves around the hip joint and the outer thigh). Participants in this study will be randomly assigned (like a coin flip) to receive either the QLESP block or the PENG+LFCN block after surgery. The study aims to determine which nerve block provides better pain relief and reduces the need for
