Lower-extremity muscle volume and strength decrease after Total Knee Arthroplasty (TKA), leading to complications such as falls and possible readmission. Perioperative essential amino acid (EAA) supplementation in patients undergoing TKA has been shown to reduce these complications. The aim of our study was to know the effects of perioperative EAA supplementation in patients undergoing TKA.Sixty four patients were analyzed in our study in which half received EAA and other half received placebo.In our study we found that patients in EAA group had better functional outcome,quadriceps muscle strength and greater quadriceps muscle diameter than placebo group.
