Tibial Spine Avulsion Repair With FiberRing Suture and Anterior Cruciate Ligament Repair TightRope

Abstract

Tibial spine avulsion fractures occur predominantly in children and young adults and are an uncommon type of knee injury. To ensure knee stability and preserve range of motion with minimal knee laxity, it is essential to restore anterior cruciate ligament length through surgical reduction and fixation of the fracture. Achieving anatomic reduction of tibial spine avulsion fractures with an arthroscopic approach is a technically complex procedure. In this Technical Note and accompanying video, we describe a unique fixation repair of tibial spine avulsion fractures using Arthrex FiberRing sutures and an Arthrex ACL Repair TightRope. The technique presented is an effective method to reduce tibial spine avulsion fractures to anatomic position with a variable tensioning system that allows for a strong and secure fixation method.
