Arthroscopic fixation of posterior cruciate ligament tibial bony avulsion fractures – The double suture bridge technique and evaluation of results.

Abstract

Introduction: 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. Materials and 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 a period of 3 year and assessed for knee related symptoms, signs, Lysholm knee score and satisfaction. Results: The study group consisted of 21 males and 3 females. Fracture union was achieved in all cases by 2 months post operative. The mean Lysholm knee score at follow up of 3 months, 6 months, 1 year, 2 years and 3 years was 86.6, 96.5, 98.8, 99.1 and 99.4 respectively. At latest follow up all the patients were satisfied with their knee function with respect to pain, range of motion, stability and resumption of pre injury activity level. Conclusion: The arthroscopic double suture bridge technique is an effective method for fixation of PCL tibial bony avulsion fractures with respect to knee stability, range of motion and resumption of pre injury activity level.
