Can a gel injection ease shoulder bursitis pain?
NCT ID NCT07729527
First seen Jul 27, 2026 · Last updated Jul 30, 2026 · Updated 3 times
Summary
This trial tests whether injecting hyaluronic acid into the shoulder, combined with physical therapy, can reduce pain and disability from subdeltoid bursitis. Fifty participants receive either cross-linked or non-cross-linked hyaluronic acid, guided by ultrasound. Researchers track pain and shoulder function for three months after treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- hyaluronic acid injection (cross-linked or non-cross-linked) combined with physical therapy
- What this could lead to
- If it works, this could point toward a non-surgical treatment option for shoulder bursitis that reduces pain and improves function.
- What could go wrong
- This is a small, early-stage trial with only 50 participants, so results may not apply to everyone. Hyaluronic acid injections can cause temporary pain or swelling at the injection site.
