Clinical Study

The Hip Functional Retrieval after Elective Surgery May Be Enhanced by Supplemented Essential Amino Acids

Table 2

Venous plasma concentration (mol/L) of amino acids measured in the entire patient population both at admission to and discharge from our rehab institute. For comparison, plasma amino acid levels in healthy subjects were reported.
