Run by University of Kentucky · NCT04572256 · Data updated 2026-11-12
This study is testing if taking montelukast for six months after ACL surgery can help older patients reduce inflammation and protect their cartilage from damage.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are individuals aged 25-50 who are undergoing primary ACL reconstruction with a concomitant meniscus injury.
✕Probably not a fit
Patients undergoing revision procedures or those without a meniscus tear at the time of surgery may not benefit from this study.

What this trial studies
This multicenter randomized, placebo-controlled trial investigates the effects of a 6-month course of oral montelukast on reducing inflammation and cartilage degradation following anterior cruciate ligament (ACL) reconstruction. Targeting older patients with ACL and meniscus injuries, the study aims to determine if montelukast can mitigate the risk of post-traumatic osteoarthritis (PTOA) progression. Participants will be randomly assigned to receive either montelukast or a placebo daily for six months after their surgery, with assessments of systemic inflammation and cartilage biomarkers conducted throughout the study.
Why it matters
Potential benefit: If successful, this treatment could significantly reduce the risk of developing post-traumatic osteoarthritis in patients undergoing ACL reconstruction.
How similar studies have gone: While the approach of using montelukast for cartilage protection is novel, previous studies have shown promise in using anti-inflammatory treatments to reduce cartilage degradation post-injury.
