posterior to the intersection of the Blumensaat’s line and a line parallel to the posterior femoral cortex. sekaiwoseisu@yahoo.co.jp. Reconstruction of the anterior cruciate ligament (ACL) is a well-established surgical procedure. Originally thought to be a sign of chronic ACL instability, several studies have shown a significant incidence of the lateral notch sign in plain radiographs associated with acute ACL tears [1,3]. Reconstruction of the anterior cruciate ligament (ACL) is a well-established surgical procedure. However, post-operative imaging in the early phase is not routinely performed. The number of ACL injuries has undoubtedly increased over the years with the greater participation of young adults in sporting activities [].Initial ground contact flatfooted or with the hindfoot, knee abduction and increased hip flexion may be risk … Author information: (1)Department of Orthopaedic Surgery, Kamimoku Spa Hospital, Minakami, Japan. Reconstruction of a ruptured anterior cruciate ligament (ACL) is a well-established procedure for repair of ACL injury. New trends in ACL imaging: ACL repair was a technique used in the ’70s–’80s with poor long-term outcome. Imaging of Anterior Cruciate Ligament Repair and Its Complications Arthur B. Meyers1 Andrew H. Haims Kirsten Menn Hicham Moukaddam ... should be oriented parallel to the Blumensaat line. However, post-operative imaging in the early phase is not routinely performed. ACL injuries most commonly occur in athletes playing multidirectional sports (1,2).Imaging is frequently used to evaluate complications in patients with postoperative symptoms. The Blumensaat line is a line drawn on conventional radiographs along the intercondy - lar roof. Iriuchishima T(1), Goto B(2), Ryu K(3), Fu FH(4). Despite improvement of surgical and rehabilitation techniques over the past decades, up to 25% of patients still fail to regain satisfactory INTRODUCTION. The readers should report on all mal-located tunnels, especially when corresponding signal In recent years ACL repair with different techniques is being performed. Purpose: The quadrant method is used to evaluate the bone tunnel position with the grid based on the Blumensaat's line in anterior cruciate ligament (ACL) reconstruction. The optimal angle of the ACL graft on coronal MR images should be less than 75 degrees in relation to a hori-zontal line (28). The Blumensaat's line morphology influences to the femoral tunnel position in anatomical ACL reconstruction. The distal portion of the tunnel should Altogether, 16 knees of 16 patients who had undergone ACL reconstruction using this system (navi group) were evaluated regarding the positioning of the tibial tunnel against Blumensaat’s line using X-p and the route of the graft by magnetic resonance imaging (MRI). The anterior cruciate ligament (ACL) is the most frequently reported injured knee ligament that requires surgical reconstruction. vertex is located greater than 20 mm posterior to the anterior portion of Blumensaat’s line [1,2]. When This study aimed to clarify the influence of variation in the Blumensaat's line … The principal findings of our study demonstrate that violation of Blumensaat line following ACL reconstruction is an indicator of vertical, nonanatomic femoral tunnel placement. The anterior cruciate ligament (ACL) injury is a common sports injury with over two million cases occurring every year.
