Could an asthma drug shield knees from arthritis after ACL surgery?

NCT ID NCT04572256

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This trial investigates whether montelukast, a common asthma medication, can reduce inflammation and prevent cartilage breakdown after anterior cruciate ligament (ACL) reconstruction. The study enrolls adults aged 25 to 50 who also have a meniscus tear, a group at high risk for rapid osteoarthritis. Participants take either montelukast or a placebo daily for six months after surgery, and researchers measure markers of inflammation and cartilage health using blood tests, MRI scans, and patient questionnaires.

Active substance

montelukast (Singulair)

What this could lead to

If it works, this could point toward a simple, inexpensive way to prevent post-traumatic osteoarthritis after ACL surgery.

What could go wrong

This is a very early, small trial (30 people) testing a drug not originally designed for joints. The results may not lead to a proven treatment.
