title: Arthroscopic Reduction of Tibial Spine Avulsion: Suture Lever Reduction Technique.
abstract: Tibial spine avulsion fractures are uncommon knee injuries that predominantly occur in children and young adults. Restoration of anterior cruciate ligament length through surgical reduction and fixation of the fracture is necessary to ensure stability of the knee with suitable range of motion and minimal knee laxity. Arthroscopic repair of tibial spine avulsion fractures is a technically complex procedure, specifically when performing and maintaining the initial anatomic reduction. We describe in this technical note and accompanying video a unique 3-point fixation repair of tibial spine avulsion fractures using an arthroscopic assisted suture lever reduction technique. Our technique is both simple and efficacious in the reduction of tibial spine avulsion fractures to anatomic position by passing the first suture through the anterior cruciate ligament, and subsequently anterior to the avulsion fragment, and then beneath the fragment through a posteriorly placed bone tunnel within the tibial fracture bed.
