Single and Double Bundle Anatomic

Did you know that ACL (Anterior Cruciate Ligament) tears can happen to any active person? Although most ACL injuries occur during sports activities, common accidents like falling off a ladder, falling down stairs or being in an auto accident can also tear your ACL.

The ACL is one of four primary ligaments that support the knee and is necessary to keep your knee stable. When the ACL tears, people often hear a “popping” sound or feel a “pop”, experience swelling in the knee within 6 hours and find it painful to put weight on the injured knee.

There are two primary ways to tear the ACL: Hyper-extension of the knee or over-rotating the knee.

  • Hyperextension: This injury occurs when the knee joint is extended 10 degrees beyond its normal range of motion. ACL tears typically occur landing straight-kneed after a jump as in basketball or volleyball or a forceful over-straightening while skiing.
  • Over-rotation: Athletes who participate in sports like soccer, basketball, volleyball and football often tear the ACL when they come to a quick stop and then pivot or change direction rapidly. Contact sports where a blow to the side of the knee occurs can also result in a torn ACL. Falls while skiing when the ski twists the knee can also tear the ACL.

The Kennedy Center’s sports medicine surgeons, Davis Tsai, MD, and Darin Leetun, MD, will evaluate your MRI and help you choose a surgical or non-surgical option that will meet your unique needs.

In ACL reconstruction surgery, a tendon is taken from another part of your body or a donor graft is used to replace your own ACL and restore knee stability. If your ACL tear is severe and you need surgery, our physicians will repair your knee using arthroscopic surgery, which minimizes trauma to the body and shortens recovery time. Both single and double tunnel anatomic ACL reconstructions are available to you at the Kennedy Center.
