Ultrasound diagnosis of pathology of the anterior and posterior cruciate ligaments of the knee joint

Summary We established a method of diagnosing pathologic conditions of both the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL) by using ultrasound. Normal ACL and PCL were delineated as hyperechoic images on the screen in sagittal and transverse sections. On the other hand, no image of the ligament could be seen when the ligament was ruptured. We examined nine ACL and five PCL injuries by our method. This is a safe and an effective method of determining the rupture of ACL and PCL.
