Stem cell byproduct may boost ACL graft healing — trial puts it to the test
NCT ID NCT07723625
First seen Jul 23, 2026 · Last updated Jul 24, 2026 · Updated 1 time
Summary
This trial tests whether adding a single injection of MSC-derived secretome — a substance produced by stem cells — during ACL reconstruction surgery can improve knee function and recovery. Twenty-four adults with a complete ACL tear will receive either the secretome or a placebo, and their knee function will be measured before surgery and six months later using standard knee scores. The goal is to see if the secretome helps the graft heal better and leads to a faster, more complete recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a single injection of mesenchymal stem cell (MSC)-derived secretome given during ACL reconstruction surgery
- What this could lead to
- If it works, this could point toward a way to speed up graft healing and improve knee function after ACL surgery.
- What could go wrong
- This is a small, early-stage trial with only 24 participants, so results may not apply broadly. The secretome is experimental, and its long-term safety and effectiveness are not yet known.
