The anterior cruciate ligament, or ACL, is one of the major ligaments of the knee that is in the middle of the knee and runs from the femur (thigh bone) to the tibia (shin bone). It prevents the tibia from sliding out in front of the femur. Together with posterior cruciate ligament (PCL) it provides rotational stability to the knee. An ACL injury is a sports related injury that occur when the knee is forcefully twisted or hyperextended. An ACL tear usually occurs with an abrupt directional change with the foot fixed on the ground or when the deceleration force crosses the knee. Changing direction rapidly, stopping suddenly, slowing down while running, landing from a jump incorrectly, and direct contact or collision, such as a football tackle can also cause injury to the ACL. When you injure your ACL, you might hear a “popping” sound and you may feel as though the knee has given out. Within the first two hours after injury, your knee will swell, and you may have a buckling sensation in the knee during twisting movements.
Unlike many other ligaments in the body, the ACL does not have the ability to heal on its own. A thick liquid – called synovial fluid – reduces friction between the bones when you move your knee. As important as this fluid is for proper knee function, it also prevents the formation of blood clots that are critical for healing. As a result, ACL tears are often treated with surgery. The first innovation in ACL surgery in several decades is bridge-enhanced ACL restoration with the BEAR® Implant.
The BEAR Implant is the first medical advancement to enable your body to heal its own torn ACL. The implant is made of collagen and is resorbed by your body within eight weeks of surgery.
The BEAR Implant works with your own blood to heal the torn ends of your ACL back together. During the procedure, the ACL surgeon adds your own blood to the BEAR Implant and inserts it between the torn ends of your ACL. The implant holds and protects the blood to allow the formation of a clot. Over the next eight weeks, the BEAR Implant is resorbed by your body and replaced with native ACL tissue.
ACL tears are often treated with surgery called ACL reconstruction, also known as ACL replacement surgery. During ACL reconstruction, an orthopedic surgeon removes the torn ACL and replaces it with a graft from another part of the body (called an autograft) or a deceased donor (called an allograft). Although ACL reconstruction is effective, the procedure has drawbacks.
- ACL reconstruction:
- Standard of care proven to be safe and effective requires incision to harvest the graft; other work done arthroscopically requires graft harvest of patient’s own tendon or cadaver tissue is used remaining ACL tissue is removed
- BEAR Restoration:
- Use of an FDA-approved bridging scaffold to repair the torn ACL requires incision to insert scaffold; other work done arthroscopically no graft harvest of patient’s tendon remaining ACL tissue is preserved
- Helps your own ACL heal
- Retains normal anatomy and function of the knee
- Simple outpatient procedure
- Does not require a second surgical wound site to remove a healthy tendon from another part of your body or use of a deceased donor’s tendon
- Faster recovery of muscle strength
- Higher patient satisfaction with being ready to return to sports
The rehabilitation protocol for the BEAR Implant is different from ACL reconstruction, but overall recovery time is similar. Return to high levels of activity and sports is usually around nine months after surgery, which is similar to ACL reconstruction.
