Abstract Avulsion fractures of the tibial eminence, although generally a rare injury pattern, are more common in children and adolescents than in adults. Many open and arthroscopic techniques are available with variable degrees of satisfying results and incidence of complications and adverse effects. Arthroscopic fixation appeared to improve the functional outcomes with fewer complications than the open fixation. New techniques were reported using commercially available suspension sling devices for the acromioclavicular joint that offers an easy and rapid method of fixation. However, this technique has the disadvantages of the presence of hardware (button) over the tibial anterior cruciate ligament attachment inside the joint and the need to drill a relatively large tunnel through the center of the avulsed fragment that may increase the chance of fracture. So small-diameter tunnels need to be drilled that will decrease bone loss and growth plate injury in children and adolescents. We describe here a technique that offers a better 4-point fixation through the anterior cruciate ligament with fewer complications by avoiding drilling through the avulsed fragment, absence of hardware inside the joint, and decreasing bone loss in adolescents by drilling only smaller transosseous tunnels and allowing for correction of the fixation using a special configuration of knots and cortical button.
