BEAR® Implant

The Bridge-Enhanced® ACL Repair (BEAR®) implant is a proprietary bio-engineered bridging scaffold to facilitate healing of the torn ACL.

The BEAR implant is designed to be surgically placed between the torn ACL ends at the time of repair, and to hold a small amount of the patient’s blood in the wound site. The combination of the BEAR implant and the patient’s blood provides a scaffold that allows the torn ends of the ACL to heal back together.

It is hoped this new technology will restore more normal anatomy and function of the knee, and thus enable a higher percentage of patients to get back to activities they enjoy.

The BEAR implant is an investigational device and is only available in FDA-approved clinical trials.

BEAR Clinical Trials

Several clinical trials are underway to study the BEAR implant and its safety and efficacy.
