Abstract
A dynamic ligament repair device includes a suture, a femoral side suture anchor and a threaded screw or housing implant. The screw is configured for placement in the tibia, or alternatively in the femur. A spring is housed inside an axial bore in the threaded screw. In some embodiments, the spring is a compression spring. A moveable spring button is positioned inside the axial bore adjacent a distal end of the spring. The spring button engages the spring directly in some embodiments. In alternative embodiments, an intermediate structure such as a spacer is positioned between the spring button and the spring. The suture extends between the spring button and the suture anchor. When the joint flexes or extends, the spring button travels inside the axial bore and dynamically compresses or relaxes the spring.
