BEAR Implant

The Bridge to ACL Restoration

The BEAR Implant is an ideal bridge designed to restore the native ACL.

Validated by Level 1 clinical evidence

No harvest site morbidity or need for donor tissue

Easy, reproducible procedure

Indicated for a broad range of ACL tear types

The BEAR Implant is a decellularized, bovine-derived, type I collagen implant that resorbs within 8 weeks of implantation.

The BEAR Implant is different.


Replaces the ACL with a graft

Primary Repair

Reapproximation of tissue with suture

BEAR Implant

Restores the native ACL

Bridges the gap between the ends of the torn ACL

Clinically effective for majority of ACL tear types, proximal to distal

The BEAR procedure is easy and reproducible.

Autologous whole blood is combined with the BEAR Implant to form a clot that bridges the gap between the torn ends of the ACL and protects the clot from the harsh synovial environment.

The BEAR Implant facilitates the body's own healing response by supporting cell migration and proliferation.

Within eight weeks, the BEAR Implant is resorbed and replaced with native cells, collagen and blood vessels. The new tissue continues to remodel and strengthen over time.

The rehabilitation protocol for the BEAR Implant has been carefully designed to help protect the ACL during the healing process. Visit the Rehabilitation Protocol page for more information.

The BEAR Implant is indicated for a broad range of ACL tear types.

The BEAR Implant offers compelling benefits.

Level 1 Clinical Evidence

  • Comparable IKDC and AP laxity scores vs. ACLR at 2 years
  • Superior in return to sport index, hamstring/quad ratio, hamstring strength, KOOS pain and symptoms*
  • Trend toward fewer complications on both ipsilateral and contralateral knees

Preservation of Native ACL Orientation

  • Restores native ACL and orientation
  • Eliminates donor site morbidity
  • Potential for more normal joint mechanics
  • Potential for decreased post-traumatic osteoarthritis (demonstrated only in animals)

‘Burn No Bridges’

  • Revisions easier than a revised ACLR
  • Early data show trend toward better outcomes with a revision after the BEAR Implant

Easy, Reproducible Procedure

  • Minimal learning curve
  • No need for deceased donor tissue, no special requirements for implant storage/ handling
  • Effective across a broad range of tear types (Type 1 through Type 4)

*As measured at 6 months, 6 and 12 months, 6 and 12 months, and 12 months, respectively.

Patients may be candidates for the BEAR Implant if they meet these criteria.

Are at least 14 years old and skeletally mature

Have a complete rupture of their ACL confirmed by MRI

Corey’s Story: First BEAR Implant Patient

In February 2015, Corey Peak became the first person to have the BEAR Implant surgery in clinical trials. Watch his story to see how he’s doing 6+ years later and learn more about how the BEAR Implant helps heal a torn ACL.

The BEAR Implant was cleared by the U.S. Food & Drug Administration through the De Novo Pathway. It is indicated for skeletally mature patients at least 14 years of age with a complete rupture of the ACL, as confirmed by MRI. Patients must have an ACL stump attached to the tibia to construct the repair.
