Posterior Cruciate Ligament reconstruction augmentation on avulsion PCL: A case series

Abstract

Introduction: Posterior Cruciate Ligament (PCL) avulsion may mimics PCL rupture with positive posterior drawer test. Treatment of choice to PCL avulsion is vary from open surgery to arthroscopic surgery. PCL reconstruction with augmentation is a rare procedure to be performed in treating PCL avulsion case. This case reported and suggested an augmentation procedure in PCL avulsion case. This study aims is to evaluate the knee functional score using augmented PCL reconstruction on PCL avulsion using peroneus longus tendon. Presentation of case: We report 3 cases, 1 male and 2 females. The result of physical examination, X-ray examination, and MRI of the knee showed a PCL avulsion. Posterior drawer test showed grade 2 result. We performed an augmented PCL reconstruction on PCL avulsion using peroneus longus tendon. Knee scoring (IKDC, Modified Cincinnati, Tegner-Lysholm) collected pre-operative and 2 years post-operative. The result of knee scoring was significant improved in post-operative compare to before surgery. Conclusion: Augmented PCL reconstruction can be considered to be an alternative treatment of PCL avulsion because the procedure has excellent post-operative knee scoring result. Highlights:

Polymeric Guide Conduits for Peripheral Nerve Tissue Engineering

“…Synthetic polymers are widely used to fabricate NGCs for peripheral nerve regeneration because they have better mechanical properties to be easily fabricated into 3D structures compared to natural polymers. The recovery period of PNI is usually approximately 3-6 months (Rhatomy et al, 2019); thus, a second surgery could be avoided using biodegradable synthetic polymers. Poly (ε-caprolactone) (PCL), an FDA-approved material, is one of the most common synthetic polymers used for the fabrication of NGCs.…”

“…PCL has excellent processability and compatibility ( Mobini et al, 2017 ). The NGCs made of PCL have excellent mechanical properties to offer topographical cues to axons for peripheral nerve regeneration; however, poor biodegradability is a major shortcoming ( Rhatomy et al, 2019 ) for the wide application of PCL. Sun et al (2006) transplanted PCL (Mw ¼ 66,000) scaffolds into rats and found that scaffolds remained structurally intact for 24 months.…”
