Supplementation with Essential Amino Acids (EAA, 20g twice daily) starting one week before and continuing two weeks after Total Knee Replacement (TKR) reduces quadriceps muscle atrophy and accelerates functional mobility recovery.
If you are having knee replacement surgery, ask your doctor or dietitian about taking Essential Amino Acid (EAA) supplements. The study suggests starting 20g of EAAs twice daily one week before surgery and continuing for two weeks after. This may help preserve your leg muscle strength and help you move better faster than standard care alone.
Patients who received essential amino acid (EAA) supplementation (20 g) prior to TKR were reported to have reduced muscle atrophy and accelerated return of functional mobility, compared to those who received a placebo supplement
Why this rating
Based on one pilot RCT (n=28) with low sample size, but clear positive findings.

- Pre-operative administration of carbohydrate-rich fluids (12.5% solution, 400-800 mL) attenuates post-operative insulin resistance and endogenous glucose release, potentially reducing hospital stay and inflammatory markers in THR/TKR patients.Moderate
- A combination of Beta-Hydroxy Beta-Methylbutyrate (HMB), L-Arginine, and L-Glutamine suppresses the loss of quadriceps muscle strength following Total Knee Replacement (TKR).Moderate

- Total daily protein intake of 1.6 g/kg/day is sufficient for maximizing resistance training-induced muscle gains, with an upper confidence interval of 2.2 g/kg/day.Strong
- Resistance exercise training combined with sufficient dietary protein intake acts synergistically to maximize skeletal muscle hypertrophy, with protein intake saturating around 1.6 g/kg/day for general populations and potentially requiring 2.0-2.2 g/kg/day for resistance-trained individuals.Strong
- Trans fats should be completely eliminated from the diet, as they increase LDL cholesterol, decrease HDL cholesterol, and are directly associated with increased coronary risk.Strong
