Comparison of arthroscopic reduction and suture fixation versus open reduction and screw fixation for anterior cruciate ligament tibial spine avulsion fractures

Background Tibial spine avulsion fractures are not uncommon injuries, with numerous published techniques for their management. However, there is no evidence suggesting the superiority of any single technique. Aim and objectives This study aims to evaluate the clinical and radiological outcomes of tibial spine avulsion fractures treated by arthroscopic reduction and suture fixation compared to those fixed by open reduction and screw fixation. Patients and methods This randomized comparative study included 26 cases of tibial spine avulsion fractures treated at the Arthroscopy and Sports Medicine Unit, Orthopedic Surgery Department, Mansoura University, between September 2020 and September 2021. Group A consisted of patients who underwent arthroscopic reduction and internal fixation with sutures, while group O included those who received open reduction and internal fixation with screws. Results Statistically significant differences were observed between the two groups. These differences included comparisons of the Lysholm score before and after surgery, subjective IKDC scores before and after surgery, anterior drawer test results before and after surgery, and preoperative and postoperative range of motion for both extension and flexion. Conclusion Our research findings indicate that patients who underwent arthroscopic reduction and suture fixation had better outcomes compared to those who underwent open reduction and screw fixation.
