The Significance of the Posterior Cruciate Ligament in the Stability of the Knee

چکیده
The significance of the posterior cruciate ligament in the stability of the knee was investigated in dogs and it was compared with that of the anterior cruciate ligament by studying the changes produced in the knee after transection of either ligament. Osteophyte formation and changes in articular cartilage were less prominent after division of the posterior cruciate ligament. A complete longitudinal tear of the medial meniscus was found in eight out of the 10 dogs who had undergone section of the anterior cruciate but in none of the 10 with section of the posterior cruciate. It appears that, in dogs at least, the posterior cruciate ligament is less important than the anterior in the stability of the knee.

The posterior cruciate ligament (PCL) is the largest and strongest ligament in the human knee, and the primary posteriorstabilizer. Recent anatomy and biomechanical studies have provided an improved understanding of PCL function. PCLinjuries are typically combined with other ligamentous, meniscal and chondral injuries. Stress radiography has becomean important and validated objective measure in...
