Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The bridge-enhanced ACL repair (BEAR) implant is a collagen-based scaffold loaded with whole blood. It is designed to promote healing in the setting of intraarticular knee pathology. This study would compare clinical outcomes and synovial fluid cytokine profiles in patients who undergo isolated meniscal repair with or without the BEAR implant.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

BEAR Implant

Adult patients with meniscus injury indicated for isolated meniscus repair. In the experimental group, the BEAR Implant will be utilized in the repair procedure.

Group Type EXPERIMENTAL

Meniscal Repair Procedure

Intervention Type PROCEDURE

All meniscal repairs will be performed by the surgeons who are listed as investigators for the study. Meniscal repair consists of arthroscopic suturing of torn fragments. This takes approximately 20 minutes. In the interventional group, the BEAR implant will be inserted through preexistent arthroscopic portals after repair is complete. This will take an additional 2 minutes.

BEAR Implant

Intervention Type DEVICE

The BEAR Implant (22 mm in diameter and 45mm in length) is cylindrical in shape and comprised of collagen and extracellular matrix derived from bovine connective tissue, which has been cleaned, disinfected and processed by a proprietary manufacturing method. The implant has been terminally sterilized by electron-beam inadiation and is intended to be used with up to 10 ml of autologous blood drawn during the surgical implantation procedure. The BEAR Implant is resorbed within 8 weeks and replaced with a fibrovascular repair tissue.

Standard Repair

adult patients with meniscus injury indicated for isolated meniscus repair. In the standard repair group, participants will undergo an isolated meniscus repair without the implant.
