All-Arthroscopic Posterior Cruciate Ligament Distal Reattachment With Extracortical Fixation.

Avulsion fractures of the posterior cruciate ligament (PCL) are a rare, but serious, knee pathology. Early surgical treatment is regarded as necessary to maintain knee stability. Recommended management involves open reduction with internal fixation through a posterior approach. However, open surgeries are associated with a greater risk of complications. Current data suggest excellent outcomes for arthroscopic-assisted fixation, with a low complication rate. The purpose of this technical note is to present an all-arthroscopic PCL distal reattachment with extracortical fixation technique. This technique provides precise fracture reduction, is easily reproducible, and is relatively safe to treat PCL tibial avulsion fractures.
