Abstract
This study aimed to evaluate the operative techniques and clinical outcomes of a minimally invasive suture bridge technique for repairing posterior cruciate ligament (PCL) tibial avulsion fractures. A retrospective analysis of 18 patients treated between January 2018 and December 2022 was conducted. The patients, aged 21 to 48 years, underwent arthroscopic surgery with a small posteromedial arc incision. The suture bridge technique was employed for secure fixation, resulting in effective fracture healing and minimal impact on the bone bed. Follow-up, ranging from 12 to 18 months, showed significant improvements in Lysholm and IKDC scores postoperatively. The technique offers a safe and efficient method, particularly suitable for comminuted fractures, with no cases of anchor loosening, refracture, or displacement observed. The minimally invasive nature of the procedure and its adaptability to various fracture types highlight its potential as a promising treatment for PCL tibial avulsion fractures.
