Outcome Analysis of Arthroscopic Fixation of Posterior Cruciate Ligament Avulsion Fracture Using a Single Tibial Tunnel and Suture Loop with Button Configuration - A Case Series Study.

INTRODUCTION

A prospective case series study to analyze the outcome of arthroscopic fixation of posterior cruciate ligament (PCL) avulsion fracture using a single tibial tunnel and suture loop with button configuration technique. PCL avulsion fracture injury requires surgical treatment to restore PCL function and stability of the knee joint. Several open and arthroscopic procedures require a steep learning curve are followed to treat these injuries; yet, our technique is a simpler technique with desirable outcomes and does not require a long learning curve. Hence, it is reported.

CASE SERIES: Ten patients with the same ethnic background having avulsed PCL injury since 2015 underwent arthroscopic fixation of avulsed PCL with single tibial tunnel and suture loop with button configuration within 3 months of injury are studied prospectively till date. All patients are clinically and radiologically evaluated with varied parameters. Postoperatively structured rehabilitation protocol is followed for all the patients. Post-operative clinical and radiological assessments are done and analyzed in 6 weeks, 3 months, 6 months, 1 year, 2 years, and 3 years.

DISCUSSION: Ten patients were available for follow-up for a period of 6 months-3 years. Outcome analysis at the end of 3 years for all patients showed definitive improvement in the function of the knee statistically and functionally.

CONCLUSION

For patients with PCL avulsion fracture, arthroscopic fixation of PCL with a single tibial tunnel and suture loop with Endobutton configuration gives definitive results. Medium-term follow-up analysis shows no failure in the outcome.
