Repairing longitudinal meniscus tears using fibrin clots
Official title: Fibrine Clot-augmented Repair of Longitudinal Meniscus Tears - A Prospectively Randomized Controlled Trial
Run by Ankara City Hospital Bilkent · NCT06541756 · Data updated 2026-11-12
This study is testing if using a special treatment called fibrin clots during surgery can help people with meniscus tears heal better than the usual repair methods.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are individuals aged 18 to 50 with a painful longitudinal meniscus tear who have not had prior surgery on the same knee.
✕Probably not a fit
Patients with additional ligament damage, previous knee surgeries, or active infections may not benefit from this study.

What this trial studies
This clinical trial aims to evaluate the effectiveness of fibrin clot-augmented meniscal repair compared to standard meniscal repair for patients with longitudinal meniscus tears. Participants aged 18 to 50 will be randomly assigned to receive either the fibrin clot-enhanced repair or conventional repair techniques. The fibrin clot will be prepared from bone marrow aspirate and used to reinforce the meniscal repair. Patients will be followed for at least one year post-surgery to assess healing rates through MRI evaluations.
Why it matters
Potential benefit: If successful, this approach could improve healing rates and long-term outcomes for patients with meniscus tears.
How similar studies have gone: While the use of fibrin clots in surgical repairs is a novel approach, similar studies have shown promising results in enhancing healing in other types of tissue repairs.
