The BEAR Implant is the ideal treatment option for partial ACL tears

Until now, most partial ACL tears were either treated non-operatively, progressing to complete tears in up to 56% of young, active patients1,2, or by ACL reconstruction (ACLR), which involved removing healthy, partially intact ACL tissue.

The BEAR implant achieves the best of both worlds:

  • Less invasive than a traditional ACLR with comparable outcomes3
  • Eliminates the need for a graft
  • Preserves healthy, intact ACL fibers
  • Restores natural function and proprioception of the knee

Stop removing healthy tissue in your partial ACL tear patients – create an optimal environment for full ACL restoration with the BEAR Implant.

"Our goal in treating patients with partial tears is to return them to a healthy, stable knee in the least invasive way possible. The clearance of the BEAR Implant for partial tears enables us to offer patients an ACL-preserving procedure to stabilize their knees."

"The BEAR Implant is the ideal treatment for partial ACL tears—it lets us preserve the patient’s native ligament, anatomy, and proprioception while enhancing healing with biology. It’s less invasive than ACL reconstruction and avoids the need to remove intact healthy tissue."

Explore the Data

A subset of data from our ongoing BEAR III trial compared two-year outcomes BEAR patients treated for partial tears (n=27) vs. complete tears (n=124):

  • Comparable IKDC subjective and physical exam results between groups
  • Similar rates of adverse events with numerically higher serious adverse events in complete tear group
  • 0% retear rate among partial tear patients

It is important to follow the BEAR Implant physical therapy program. Your surgeon can explain the program details.

Be sure to discuss your individual symptoms, diagnosis and treatment with your surgeon. The BEAR Implant has the same potential medical/surgical complications as other orthopedic surgical procedures, including ACL reconstruction. These include the risk of re-tear, infection, knee pain, meniscus injury and limited range of motion.

The BEAR Implant was cleared by the U.S. Food & Drug Administration and is indicated for adults, adolescents and children with a complete or partial rupture of the ACL, as confirmed by MRI. Patients must have an ACL stump attached to the tibia to construct the repair. Children with open physes must have sufficient bone in the femoral and tibial epiphyses on either side of the intended tunnel locations to avoid disruption of the growth plates.

It is important to follow the BEAR Implant rehabilitation program. Your surgeon or physical therapist can explain the program details.
