Branched Chain Amino Acids for Sarcopenia in Patients Undergoing Total Knee Arthroplasty

Summary

This multicenter, prospective, randomized controlled trial evaluates whether postoperative administration of branched chain amino acids affects skeletal muscle mass index and sarcopenia related functional outcomes in patients undergoing total knee arthroplasty. Participants are randomly assigned to receive Livact granules 4.15 g three times daily for 3 months after surgery or to receive standard postoperative care without branched chain amino acid administration. Skeletal muscle mass index, physical function, patient reported outcomes, laboratory findings, medication compliance, and adverse events are assessed at baseline, 5 weeks, and 15 weeks after surgery.
