Bridge-enhanced anterior cruciate ligament repair (BEAR) combines suture repair of the anterior cruciate ligament (ACL) with a specific extracellular matrix scaffold (the BEAR scaffold) that is placed in the gap between the torn ends of the ACL to facilitate ligament healing. The BEAR Implant is indicated for skeletally mature patients at least 14 years of age with a complete rupture of the ACL, as confirmed by MRI. Only a single bundle repair of a double bundle ligament means the knee is left rotationally less stable (10), The graft tendon goes in at a steeper angle than the original ACL; hence its more likely to shear and fail (9), No working position sensors in the tendon repair of a ligament mean less position sense (6-8), High likelihood of developing arthritis/doesnt prevent arthritis (11,12), Higher chance of tearing the ACL on the other knee (13), The hamstrings or quadriceps muscles become weaker due to the graft harvest (14), A much less invasive procedure than surgery.

In a randomized controlled trial of 100 people who experienced complete ACL rupture, 65 received the implant and 35 members in a control group had reconstruction via autograft, using tendon from their own bodies. Every patient underwent physical therapy after surgery, and the team followed them for two years. The homogeneous low signal intensity (black) in some patients (eg, top row [first from left] and bottom row [second from left]) is typical of the normal in situ hamstring tendon because of highly organized connective tissue with little free water. Hence, any implant procedure requiring tunnels to be drilled will likely harm cartilage.

(HealthDay)An anterior cruciate ligament (ACL) implant that offers an alternative to traditional ACL reconstruction has received marketing authorization from the U.S. Food and Drug. Marketing authorization allows manufacturers to bring a medicinal product to the market. Bridge-enhanced ACL repair (BEAR) is a new FDA-approved procedure that allows a torn ACL to heal itself and does not require graft tissue to be taken from another part of the body. This difference in injury risk is an important focus of research and has been attributed to anatomy, hormonal effects, neuromuscular control, biomechanics, and sport participation.

What if you could skip the surgery and instead have your Bone Marrow Concentrate (BMC), which contains healing stem cells, injected into your ACL? The recent trial results showed that 14% of patients required ACLR surgery despite the BEAR surgery (1). This is a potential problem as the natural ACL has two bands that cross each other (hence the name Cruciate, which in Latin means cross). The bridge enhanced ACL restoration (BEAR) procedure provides the ability to perform primary repair of the acutely torn ACL's via utilization of a proprietary protein based scaffold. That's a big deal, because until now your ACL would have been replaced with either another tendon from your body or a tendon from a deceased donor.
