A total of 30 patients who underwent endoscopic reconstruction of the anterior cruciate ligament using quadrupled hamstring tendons, through a single drill hole in the femur, had MRI 24 to 28 months after operation. In 18 patients the scans revealed that both the anterior and posterior portions of the graft ran in parallel from the inside of the femoral to the tibial tunnel. In 12, the posterio...

Nowadays, the use of synthetic grafts to bypass occluded arterial sections is common practice in clinics and hospitals. Success has been achieved in cases involving large diameter blood vessels. However, for arteries with a diameter less than 5 mm, the success rates for synthetic grafts have been low mainly due to intimal hyperplasia formation at anastomoses. The postulated reasons affecting gr...

Contact between an anterior cruciate ligament graft and the intercondylar roof has been termed roof impingement. Grafts with impingement sustain permanent damage, and if the injury is extensive enough, then the graft may fail, causing recurrent instability. This study evaluated two mechanical factors that could be responsible for the graft injury associated with roof impingement: an increase in...

Interference screws are commonly used for graft fixation in bonetendon-bone patellar tendon anterior cmciate ligament (ACL) reconstruction. The clinical significance of graft screw divergence has not been well studied. This report retrospectively reviews our initial experience in 73 consecutive endoscopic (single-incision) ACL reconstructions using interference screw fixation. Femoral divergenc...

A technique for stabilising the superior tibiofibular joint using an autogenous biceps graft passed through a tibial tunnel is described. The common peroneal nerve should be decompressed and the lateral inferior genicular artery protected. The technique proved to be safe and effective in two patients who were followed for at least two years.

We report on an unusual case of surgical repair for anomalous origin of the coronary artery from the pulmonary artery, in a young patient who underwent tunnel repair with concomitant heterotopic heart transplantation to support severely impaired left ventricular function. Four years later, the graft was removed after confirmation of ventricular arrest and excellent recovery of the patient's own...

INTRODUCTION: The hamstring tendon autograft is widely used for anterior cruciate ligament reconstruction because of its superior tensile strength and lower donor site morbidity. The successful reconstruction surgery depends on not only initial graft fixation but also biologic integration of the graft. The healing process of transplanted tendon graft to bone via the development of fibrovascular...

This value analysis brief presents information on the design features and potential procedural benefits of using the DePuy Synthes Mitek Sports Medicine SPEEDTRAPTM Graft Preparation System, a whipstitch suture delivery device created to simplify soft-tissue graft preparation. The SPEEDTRAP System is designed to apply uniform, consistent whipstitches to the graft faster and easier than traditio...

Rupture of the anterior cruciate ligament is one of the most common ligament injuries in sports traumatology. The need for surgical anterior cruciate ligament reconstruction is justified by its anatomical characteristics. Key considerations when choosing a graft include the potential for bone integration and the risk of failure. Bone sclerosis around the tunnel affects the integration of the gr...

BACKGROUND The double-bundle technique has recently gained much interest in ligament reconstruction. In addition to potential kinematic advantages, perhaps double tunnels have the potential for faster and more secure tendon-to-bone healing. HYPOTHESIS Placement of tendons in 2 osseous tunnels, as opposed to 1, will enhance tendon fixation as determined biomechanically and histologically. ST...
