The main questions it aims to answer are:\n\n1. Does sarcopenia affect the onset time and success rate of peripheral nerve blocks?\n2. How does sarcopenia influence postoperative pain control and opioid consumption compared to patients receiving pure general anesthesia?\n\nParticipants will undergo a preoperative muscle assessment, which includes a chair stand test and a brief ultrasound of the thigh muscle. Researchers will then observe and record their nerve block onset time (if applicable), postoperative pain scores, and recovery metrics during their hospital stay up to postoperative day 2.",[81,37],"Sarcopenia","NOT_YET_RECRUITING","2026-08-06",{"date":85,"type":86},"2026-08-11","ACTUAL",{"date":88,"type":77},"2026-09-01",{"date":90,"type":77},"2028-08-31",{"name":5,"class":6},1]
