Based on a systematic review of the literature, this chapter will present the current knowledge on arterial complications, venous thromboembolism (VTE), and thromboprophylaxis after arthroscopic ACL reconstruction. Enter the MRI (9 days after the injury): Two acutely torn ACLs. The Endobutton is a device that is pushed through a small hole in the bone and then deploys as a T to anchor the graft in place . So no issues there. 5,[13][14][15][16]36 This technique allows for technical . Methods: We reviewed prospectively collected outcome data on consecutive patients who had undergone transphyseal ACL reconstruction at . Next: what to do about it. femoral and tibial tunneling graft fixation on the femoral side with endobutton and on . Graft failure is defined as pathologic laxity of the reconstructed ACL. In general, it can be demonstrated that there is a 7-21% weakness of knee . The ENDOBUTTON CL ULTRA device is supported by over 10 years of clinical experience and more than 20 peer-reviewed journals. 2019 Congress The anterior cruciate ligament (ACL) is one of the most commonly injured ligaments of the knee in contact sports players. Meniscal and ligamentous tearing are the most frequent indications for . Then, we review commonly . The aim of this study was to describe the contrast-enhanced magnetic resonance imaging (MRI) appearance of bone tunnel enlargement detected on radiography after anterior cruciate ligament (ACL) reconstruction with semitendinosus and gracilis tendon endobutton (STG-endobutton) fixation technique. An anterior cruciate ligament (ACL) rupture is one of the most common knee injuries in sports. The reduced mechanical properties of the tissue in EDS can pose a challenge to the orthopaedic surgeon. The TightRope Attachable Button System (ABS) is a 2-piece implant that can be passed through narrow bone tunnels, while allowing increased cortical fixation with the assembly of a large button over the cortical bone. A first-in-human study 8 suggested the safety and efficacy of this approach in restoring knee stability and function, and a later study focused on magnetic resonance imaging . Correct isometric placement is crucial to the Right and Left knee MRI with evidence of torn ACLs bilaterally (thin red line-that smushed/smeared grey blob should be a nice black line).
