Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

Researchers compare two light-based treatments, low-level laser therapy and infrared therapy, for people with a Grade II anterior cruciate ligament (ACL) injury, a partial tear that causes knee pain and limits movement. Thirty participants aged 15 to 45 will be assigned to one of two groups. Both groups receive the same standard physiotherapy, including range-of-motion and strengthening exercises, five days a week for four weeks. One group also gets laser treatment and the other gets infrared treatment. The study measures changes in pain and in psychological readiness to return to activity.

What this could mean

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

Active substance
low-level laser therapy and infrared therapy, two light-based devices added to standard physiotherapy
What this could lead to
If one therapy helps more, physiotherapists could have a clearer choice for easing pain and rebuilding confidence during ACL rehab.
What could go wrong
This is a small, short study of 30 people over four weeks, so any difference between the two therapies may be modest or fade. Light therapy can cause minor skin warmth or irritation, and results may not apply to other ACL grades.
