Summary

This trial tests whether pulsed electromagnetic field (PEMF) therapy can improve hamstring muscle strength recovery in people who had ACL reconstruction using their own hamstring tendon. Participants will receive either real PEMF or a placebo treatment, with both groups using the same machine. The goal is to see if PEMF helps the donor site heal better and reduces the common muscle weakness after surgery.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Pulsed electromagnetic field (PEMF) therapy, a non-invasive device that delivers magnetic pulses to the knee to promote tissue repair and muscle regeneration.
What this could lead to: If effective, PEMF could offer a drug-free, non-invasive way to speed up hamstring recovery after ACL surgery, potentially reducing muscle weakness and improving knee stability.
What could go wrong: This is an early-stage trial with a small number of participants, so results may not apply broadly. The therapy's benefit over placebo is unproven, and individual outcomes may vary.
