Abstract

Background: Surgical fixation is required for displaced posterior cruciate ligament (PCL) tibial bony avulsion fractures or with fractures having grade 2 or more posterior instability. The purpose of this study is to evaluate the results of arthroscopic fixation of PCL tibial bony avulsion fractures using the double suture bridge technique.

Methods: A retrospective study was done involving 24 patients having displaced PCL tibial bony avulsion fractures. The arthroscopic double suture bridge technique was used to fix these fractures. Patients were followed up for three years and assessed for knee-related symptoms, signs, Lysholm Knee Score, and satisfaction.

Results: The study group consisted of 21 men and three women. Fracture union was achieved in all cases two months postoperatively. The mean Lysholm Knee Score at follow-ups of three months, six months, one year, two years, and three years was 86.6, 96.5, 98.8, 99.1, and 99.4, respectively. At the latest follow-up, all the patients were satisfied with their knee function with respect to pain, range of motion (ROM), stability, and resumption of pre-injury activity level.

Conclusion: The arthroscopic double suture bridge technique is an effective method for the fixation of PCL tibial bony avulsion fractures with respect to knee stability, ROM, and resumption of pre-injury activity level.
