AUGMENTATION POSTERIOR CRUCIATE LIGAMENT RECONSTRUCTION USING PERONEAL LONGUS TENDON ON AVULSION PCL : CASE SERIES

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. 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, TegnerLysholm) collected pre-operative and 2 years post-operative. The result of knee scoring was significant improved in post-operative compare to before surgery. Discussions: The use of conventional screw on thin, small, and comminuted fragments cannot fix the bone and may causes bone fragmentation. Fixation technique using sutures produces unstable results and does not provide maximum pressure to fix the bone. Augmented PCL reconstruction surgery gives excellent result based on knee scoring system. 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.
