Summary

This study tests whether taking branched-chain amino acid (BCAA) supplements for three months after knee replacement surgery can help improve muscle mass and strength in patients with sarcopenia (age-related muscle loss). About 140 adults aged 40 to 100 will be randomly assigned to receive either BCAA granules or standard care. Researchers will measure muscle mass, grip strength, and physical function at 5 and 15 weeks after surgery.
