Suture Bridge Technique for Arthroscopic Repair of Posterior Cruciate Ligament Tibial Avulsion.

Arthroscopy has gradually become the routine method to treat posterior cruciate ligament tibial insertion avulsion. However, arthroscopic surgery possesses the advantages of being minimally invasive, having a good appearance, and having no need for revision surgery for internal fixation. Compared with open surgery, it is limited by disadvantages such as unstable fixation, unsatisfactory reduction, and fracture fragment displacement. After comparing the various methods proposed in the literature, the "suture bridge" technique, which is commonly used for rotator cuff treatment, is used for repair of posterior cruciate ligament tibial insertion avulsion in combination with the double posterior medial arthroscopic portals, is applied by our team. This surgical technique enables the even distribution of sutures above the fracture fragment, reduces the possibility of suture displacement, and enables excellent reduction under arthroscopy while fully preserving the posterior septum.
