Arthroscopic Posterior Cruciate Ligament Primary Repair

Background: Injuries to the posterior cruciate ligament (PCL) are common in cases of knee trauma and often occur alongside other ligament injuries. These injuries can lead to significant functional impairment and, if untreated, are associated with a higher risk of developing osteoarthritis. Traditionally, surgical intervention for severe PCL injuries has involved reconstruction rather than repair. However, recent advances in surgical techniques and imaging have led to a reevaluation of primary arthroscopic repair for proximal PCL tears, especially when tissue quality is adequate. Methods: This study describes a new surgical technique for primary arthroscopic repair of proximal PCL tears using a suturing device known as the FiberRing, along with an adjustable cortical button for fixation (ACL Repair TightRope). The aim of this approach is to minimize invasiveness while preserving the native ligament and addressing common issues faced in previous techniques, such as suture wear and inability to loosen the ligament after fixation. Results: The authors report that the proposed method allows for effective tensioning and loosening of the PCL during surgery. After initial stabilization, surgeons can assess posterior drawer laxity through knee cycling and adjust tension as needed. This flexibility is crucial as excessive tension poses a significant risk. Results indicate that this technique not only preserves the structural integrity of the PCL but also enhances patient outcomes by potentially reducing recovery time and complications associated with graft harvesting seen in traditional reconstruction methods. The study emphasizes that although long-term results are not yet fully established, initial findings suggest that primary arthroscopic repair can be a suitable alternative for select patients with proximal PCL injuries. Conclusion: Primary PCL repair via arthroscopy shows promising advancements in knee surgery, particularly for patients with proximal tears. This technique offers a minimally invasive option that preserves native ligament tissue while addressing the limitations of traditional reconstruction methods. As surgical techniques continue to evolve, further research is essential to evaluate long-term outcomes and refine patient selection criteria.
