To view objects at different distances, humans rely on vergence eye movements to appropriately converge or diverge the eyes and on ocular accommodation to focus the object. Despite the importance of these coordinated eye movements (the 'near response') very little is known about the role of the cerebral cortex in their control. As near-response neurons(More)
AIMS Progressive deterioration of glycaemic control in type 2 diabetes mellitus (T2DM) often requires treatment intensification. Dapagliflozin increases urinary glucose excretion by selective inhibition of renal sodium-glucose cotransporter 2 (SGLT2). We assessed the efficacy, safety and tolerability of dapagliflozin added to glimepiride in patients with(More)
BACKGROUND Several controversies exist regarding the superiority of double-bundle (DB) posterior cruciate ligament (PCL) reconstruction versus single-bundle (SB) reconstruction, although DB reconstruction has been shown to restore the intact knee kinematics more closely than SB reconstruction. HYPOTHESIS Double-bundle PCL reconstruction will present(More)
PURPOSE We describe an anatomic reconstructive surgical procedure that simultaneously reconstructs the fibular collateral ligament, popliteal tendon, and popliteofibular ligament using split Achilles allograft, and compare the clinical results of this technique with those of the posterolateral corner sling procedure for posterolateral instability of the(More)
The purposes of this study are to confirm factors that affect the diameter of hamstring tendon autograft and to compare failure rates between the factors after anterior cruciate ligament (ACL) reconstruction. A total of 296 patients that underwent reconstruction using hamstring tendon autograft at our clinics for ACL injury between September 2005 and June(More)
BACKGROUND The present study examined the prevalence of bone contusions in patients with anterior cruciate ligament (ACL) injury as well as its association with tears of the lateral meniscus, medial meniscus, and medial collateral ligament (MCL). METHODS Eighty-one patients with an arthroscopy-proven ACL rupture for whom magnetic resonance images (MRI)(More)
The results of 11 total knee arthroplasties in 9 patients with a Charcot joint secondary to neurosyphilis were reviewed. The mean age was 60.1 years, and follow-up averaged 12.3 years. Endomodel rotating hinge prostheses (Waldemar Link GMBH and Co, Hamburg, Germany) were implanted in all knees. The mean knee score increased from 44.9 before surgery to 95.0(More)
PURPOSE To evaluate the clinical and radiologic results, second-look arthroscopic findings, histologic evaluation, and results of immunohistochemical staining and the Western blotting test for type II collagen after microfracture for full-thickness chondral defects in patients with osteoarthritic knee. METHODS Between October 1997 and December 1998, 49(More)
PURPOSE The purpose of this study was to analyze differences in injury mechanism, preoperative physical examination findings, combined injury pattern, and postoperative clinical results among arthroscopic anterior cruciate ligament (ACL) reconstruction, anteromedial (AM) augmentation, and posterolateral (PL) augmentation with hamstring autograft. We also(More)
