Fish oil and protein powder: a new recipe for knee surgery recovery?
NCT ID NCT06233825
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study tested whether taking omega-3 fatty acids (fish oil) and essential amino acids (protein building blocks) before and after knee surgery could help prevent muscle loss. Thirty adults scheduled for ACL reconstruction took either the supplements or a placebo for 4 weeks before and 2 weeks after surgery. The main goal was to see if such a study is feasible, while also measuring muscle mass and strength changes.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Omega-3 fatty acids (fish oil) and essential amino acids
What this could lead to
If this approach works, it could point toward a simple nutritional supplement to help people regain muscle strength faster after knee surgery.
What could go wrong
This is a very small pilot study (30 people) focused on feasibility, not proof of effectiveness. The results may not apply to everyone, and the supplements may not provide significant benefit over standard recovery.
