Advantages and Limitations

Advantages Effective therapeutic solution for PCL/PMB augmentation in patients with symptoms after hyperextension knee trauma. May allow for a proper knee laxity restoration and pain relief in patients with an often-overlooked isolated PMB injury. Because it is a nonanatomic technique, it avoids a possible iatrogenic injury to the ALB. It may be performed either with a hamstring autograft or allograft.

Limitations Requires advanced skills in arthroscopic surgery and a non-negligible learning curve. Requires small incisions besides the arthroscopic portals to perform graft harvesting. Challenging diagnosis of the isolated PMB injury after a hyperextension trauma.

ALB, anterolateral bundle; PCL, posterior cruciate ligament; PMB, posteromedial bundle.
