Posterior Cruciate Ligament (PCL) Reconstruction: New Concepts

Abstract

Although injuries to the posterior cruciate ligament (PCL) are uncommon and have been infrequently studied, the anatomy of the structure including its origin, attachment, and surrounding structures has been well characterized. Based on the severity of the mechanism of injury, other adjacent structures may be affected and a careful physical examination is important. Additionally, imaging including x-rays, MRI, and CT can provide important information. Many PCL injuries can be treated without surgery, but recent studies have demonstrated that patients are at a greater predisposition for developing degenerative changes. Surgery is performed for instability and combined ligamentous injuries and may include single-bundle and double-bundle reconstructions and transtibial and tibial-inlay techniques, either through open or arthroscopic methods. In the chapter, the authors have outlined their preferred method of the open, tibial-inlay technique with accompanying pearl and pitfalls for this technique.
