Tibial avulsions of the posterior cruciate ligament (PCL) require surgical intervention. Several arthroscopic strategies exist to fix the fragment, including two types of suspension button devices: adjustable (self-locking) and rigid knotted systems. Our hypothesis was that a rigid knotted button construct has superior biomechanical properties regarding laxity restoration compared with an adjustable system. Both techniques were compared with standard screw fixation and the native PCL in a porcine model.
