Abstract
Purpose: Numerous techniques for treatment of anterior cruciate ligament (ACL) avulsion fractures have been described in literature from closed reduction to definitive fixation, both open and arthroscopically assisted fixation. The present study aims to evaluate the clinical outcome of arthroscopic suture bridge fixation technique. Methods: The present retrospective study includes 31 patients with documented ACL avulsion fractures between 2008 and 2015. They all underwent arthroscopic suture bridge fixation by the same lead operating surgeon. The inclusion criteria were a displaced ACL avulsion fracture (Meyer and McKeever Types 3 and 4), with a minimum completed follow-up of 18 months. All patients were assessed with a preoperative magnetic resonance imaging to confirm the fracture. Results: Radiographs taken postoperatively showed that all avulsed fragments reduced were maintained and healing was evident in all cases by the end of 3 months. Clinically, no symptoms of instability were called for and no signs of ACL deficiency were elicited. Range of motion measurement showed a mean extension deficit of 2° (0-4) and a mean flexion deficit of 3° (1-6) when compared with the unaffected knee. The average Lysolm knee score was 98 (96-100). Conclusion: The present study demonstrated arthroscopic suture bridge fixation as a successful surgical intervention procedure for treatment of ACL avulsion fractures.
