A simplified algorithm to work up graft re-rupture following anterior cruciate ligament reconstruction

The need to perform revision anterior cruciate ligament reconstruction (ACLR) has several etiologies such as infection, arthrofibrosis, cyclops lesions, and graft failure, which should be distinguished before revision ACLR. Even the definition of graft failure varies within the literature. ACLR graft failure falls into modifiable, surgeon-controlled factors, such as tunnel position, graft choice, and alignment, and nonmodifiable factors, such as patient age, tissue quality, or secondary traumatic reruptures. In this review, we describe a facile framework for the workup of modifiable ACLR graft failure.
