Figure 10. A: view from a transpatellar (Gillquist) portal. From the posteromedial working portal we use radiofrequency to clean the tibial insertion site of the posterior cruciate ligament (PCL) which is located in the posterolateral zone of the posterior root of the medial meniscus (arrow); B: view from a posteromedial portal. Fully cleaned tibial insertion site with the arrow indicating the posterior root of the medial meniscus.
