Arthroscopic Primary Repair of Mid-Substance Posterior Cruciate Ligament Tears With Knotless Dual-Suspensory Fixation

Posterior cruciate ligament (PCL) tears can spontaneously heal, but often heal with excess laxity. In contrast to well-documented arthroscopic proximal and distal PCL tear repairs, the most prevalent mid-substance tear is typically managed conservatively, or with full reconstruction. We describe an arthroscopic technique for mid-substance PCL repair, applying construct elements from current anterior cruciate ligament repair to bidirectionally unite the 2 halves of the torn PCL, then reinforce the repair with suture tape. This all-arthroscopic repair aims to directly restore PCL continuity and maintain tension, without compromising its inherent healing potential.
