Shockwave therapy tested for Post-ACL knee pain
NCT ID NCT07580157
First seen Jun 27, 2026 · Last updated Aug 07, 2026 · Updated 1 time
Summary
This study at Mayo Clinic is testing whether focused shockwave therapy can reduce pain at the front of the knee after ACL reconstruction. Twenty adults who had ACL surgery using a tendon graft will receive either real shockwave or a sham treatment. Researchers will measure changes in knee function and pain using patient questionnaires.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- focused shockwave therapy
- What this could lead to
- If it works, this could offer a non-drug option to reduce knee pain after ACL surgery, helping people recover more comfortably.
- What could go wrong
- This is a very small early study with only 20 people, so results may not apply to everyone. The treatment is compared to a sham (fake) procedure, so any benefit might be due to a placebo effect.
