Single-Bundle Posterior Cruciate Ligament Reconstruction With Suture Tape Augmentation and Transtibial Tubercle Fixation.

The posterior cruciate ligament (PCL) is the strongest ligament of the knee and plays an important role in stabilizing the knee joint posteriorly. PCL tears are common injuries in sports injuries and traffic accidents; however, clinical outcomes after PCL reconstruction have not yet met clinicians' expectations, with a high postsurgery failure rate reported. Suture tape augmentation and supplementary fixation have shown ideal biomechanical properties in early studies. In this Technical Note, we describe a surgical technique to reconstruct the PCL with suture tape augmentation and transtibial tubercle fixation; the PCL remnant is also preserved. This technique is deemed to improve posterior stability and ultimate failure load for PCL graft over traditional techniques.
