The Delta Technique for Anterolateral Ligament Reconstruction
The Delta technique refers to the method of reconstruction of the anterolateral ligament (ALL) with a proximal fixation point and two 'tails'. This method is what we are moving to as a group. But we need to fine-tune our landmarks as you see at the beginning of this video.
At the very interesting November 2015 meeting - the Anterolateral Ligament Experts Meeting - in Lyon. Bertrand Sonnery-Cottet did a insightful cadaveric demonstration of his Delta ALL reconstruction, which is where he feels we should be going. He described a beautiful technique doing a delta ligament with one tunnel on the femur and two sockets on the tibia.
I myself think this is a little tricky to carry out - I have tried it on my patients and it’s a good technique, but I think it is making it more difficult than we need to. So my preferred technique now is to make a complete tunnel on the tibia.
