Adjustable Button Devices for All-Arthroscopic Posterior Cruciate Ligament Reconstruction Using the Hamstrings Tendons and the "Forgotten" Transseptal Approach.

Posterior cruciate ligament (PCL) ruptures account for nearly 20% of all ligamentous knee injuries. These may be either isolated or in the setting of a more complex knee trauma. Isolated tears with moderate posterior laxity (grades I or II) are commonly treated conservatively; nevertheless, symptomatic grade III injuries frequently require surgical intervention. PCL reconstruction remains a challenging surgery for multiple reasons like the neurovascular structures' proximity, the difficult passage of the graft with the "killer turn" angle, or the risk of poor graft fixation. We describe an all-inside operative technique using hamstrings tendon autografts with tibial and femoral adjustable buttons cortical fixation and the visualization of the posterior transseptal portal.
