Management of comminuted tibial end bony avulsion of posterior cruciate ligament by open posterior approach using suture bridge technique: A case series

Background Comminuted tibial end bony avulsion of posterior cruciate ligament (PCL) is a challenging problem in terms of accurate reduction, fixation and union to provide a stable knee. Arthroscopic reduction or a screw fixation is good option for a large fragment but comminuted fragment reduction remains a challenge. Suture bridge technique using two anchors can provide an accurate reduction and stable fixation. Method 10 patients of isolated comminuted PCL avulsion with a mean age of 30 years were fixed by standard posterior approach using suture bridge technique. Results Mean follow up was 12 months. All patients showed radiological union at 12 weeks with a mean Lysholm score of 92. Seven out of ten achieved IKDC grade A and remaining three had grade B. No complication of the procedure were noted. Conclusion Suture bridge technique is an excellent option to fix a comminuted PCL avulsion fracture where arthroscopic reduction or open single screw fixation is not a viable due option due to comminution.
