Tibial Spine Avulsion Fracture Fixation Using a Re-tensionable All-Suture Construct.

Abstract

Tibial spine avulsion injuries, including fractures, are a variant of anterior cruciate ligament injuries. Treatment historically consisted of open reduction and internal fixation of the avulsion fracture, with anterior cruciate ligament reconstruction considered in cases of failed open reduction and internal fixation or residual laxity. However, improved instrumentation has led to the advancement of various arthroscopic techniques for addressing these injuries. The emergence of newer implants designed for all-suture fixation has also overcome the limitations associated with screw fixation, such as hardware-related complications, challenges in treating comminuted fractures, and potential physeal injury. The purpose of this article is to describe a technique consisting of arthroscopic-assisted reduction and internal fixation of a tibial spine avulsion fracture with a re-tensionable all-suture-based construct using multiple looped cinch stitches and a cortical suspensory suture button device.
