Assessment of Outcomes of Double-bundle Posterior Cruciate Ligament Reconstruction (DB-PCLR)

Study Overview
=================
Brief Summary
-----------------
Double-bundle Posterior Cruciate Ligament Reconstruction (DB-PCLR) is becoming increasingly used alternative to the single-bungle PCLR. While more technically challenging, it seems to better improve patients' outcomes. Therefore, outcomes of DB-PCLR will be assessed and reported.
