The Bridge to Natural ACL Restoration

The BEAR® Implant serves as a bridge to restore the patient’s native ACL, enabling the knee joint to function more naturally

Preserves knee anatomy and landmarks

No grafts or donor tissue required

Clinically proven efficacy across a broad range of tear types

Validated by Level 1 clinical evidence

BEAR vs. Standard of Care

the current standard of care for acl injuries:

Reconstruction

  • Replaces the ACL with a graft
  • Risk of donor site morbidity

What Makes THE BEAR IMPLANT Different

THE BEAR IMPLANT
  • Allows the body to restore its own ACL
  • Creates a protective environment for healing
  • Preserves natural knee joint function & anatomy

BEAR Procedure

Autologous whole blood is combined with the BEAR Implant to form a clot that shields the two torn ends of the ACL from the harsh synovial fluid, creating a protective environment conducive to healing.

The BEAR Implant facilitates the body's own natural 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.

Benefits

Restores the Patient’s Natural ACL

  • Preserves native ACL anatomy and orientation
  • Enables the knee joint to function more naturally
  • Eliminates graft harvest site morbidity or need for donor tissue
  • Potential for decreased post-traumatic osteoarthritis (demonstrated in animals)

Supported by Level 1 Clinical Evidence

  • Comparable IKDC and AP laxity scores vs. ACLR at 2 years
  • Superior hamstring strength & hamstring/quad ratio1
  • Reduced patient-reported KOOS symptoms2
  • Superior return to sport index3

Burns No Bridges

  • Less complicated revision vs. ACLR with trend towards better outcomes
  • Bone tunnels are ≤ ½ the size of ACLR tunnels

Straightforward, Reproducible Procedure

  • Minimal learning curve
  • No special requirements for implant storage/handling
  1. At 6 months, 12 months, and 2 years post-operative.
  2. At 1 year post-operative.
  3. At 6 months post-operative.

Eligibility

Patients may be eligible for the BEAR Implant if they have a partial or complete ACL tear as confirmed by MRI. While patients in our early clinical studies were required to have surgery within 50 days of ACL injury, real world experience has shown ACL tissue quality, not time, determines eligibility for the BEAR Implant.

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