Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The displaced meniscal fragment can cause mechanical symptoms such as locking, clicking, or catching of the knee, as well as pain and swelling. If not properly treated, buckle-handle meniscal tears can lead to further complications, including chronic knee instability, increased risk of osteoarthritis, and persistent joint pain.Repairing a longitudinal meniscal tear offers several advantages over partial meniscectomy, particularly in preserving knee function and preventing long-term complications.
Meniscal repair aims to restore the integrity of the meniscus, which plays a crucial role in load distribution, shock absorption, and joint stability.
Utilizing a fibrin clot during the repair of a buckle-handle meniscal tear can enhance the healing process and improve surgical outcomes. Fibrin clots act as a biological scaffold, promoting tissue regeneration by providing a matrix that facilitates cellular migration and proliferation.
The purpose of this study was to compare longitudinal meniscal tear repair reinforced with fibrin clot with routine end-to-end repair in a prospective randomized controlled trial.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Patients in the standard repair group will undergo routine meniscus repair surgery using arthroscopic all-inside or inside-out sutures, with spinal anesthesia. For the fibrin clot group, a fibrin clot will be prepared from 50cc of bone marrow aspirate obtained from the iliac crest and mixed for 15 minutes. The fibrin clot will be shaped into a cylindrical form and compressed between the torn edges of the meniscus using a trocar system, then secured with sutures. After completing the repairs, the surgical wounds and portals will be closed, and an elastic bandage will be applied. The post-operative rehabilitation protocols will be the same for all patients.
Patients will be clinically followed for at least one year, with healing rates compared using control magnetic resonance imaging at the end of the first year.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Fibrin Clot-augmented group
Patients in the experimental repair group will undergo routine meniscus repair surgery in addition to a fibrin clot placed within the ruptured sides using arthroscopic all-inside or inside-out sutures. The fibrin clot will be prepared from 50cc of bone marrow aspirate obtained from the iliac crest and mixed for 15 minutes. The clot will be shaped into a cylindrical form and compressed between the torn edges of the meniscus using a trocar system, then secured with sutures.
Fibrine Clot-augmented Meniscal Repair
The fibrin clot will be prepared from 50cc of bone marrow aspirate obtained from the iliac crest and mixed for 15 minutes. The fibrin clot will be shaped into a cylindrical form and compressed between the torn edges of the meniscus using a trocar system, then secured with sutures.
Conventionally repaired group
Patients in the control repair group will undergo routine meniscus repair surgery using arthroscopic all-inside or inside-out sutures. The ruptured sides will be approximated as usual and the procedure will be considered completed.
Conventional Meniscal Repair
Patients in the standard repair group will undergo routine meniscus repair surgery using arthroscopic all-inside or inside-out sutures.
