ACL Tears & Treatment

Anterior cruciate ligament (ACL) tears are a common sports injury. Every year, approximately 400,000 injuries to the ACL occur in the U.S. The ACL is one of the four primary ligaments that provide stability to the knee joint. Without treatment, the ACL does not heal, resulting in ACL reconstruction surgery being one of the most common orthopaedic procedures in the U.S.

ACL reconstruction stabilizes the knee, but has a number of drawbacks:

BEAR® Implant

The Bridge-Enhanced® ACL Repair (BEAR®) Implant is a proprietary bio-engineered bridging scaffold to facilitate healing of the torn ACL and is an alternative to the current standard reconstruction treatment for torn ACLs. Use of the BEAR technology does not require a second surgery to harvest the patient's own tissue as required with autograft reconstruction.

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.
