Although over 30 common genetic susceptibility loci have been identified to be independently associated with coronary artery disease (CAD) risk through genome-wide association studies (GWAS), genetic risk variants reported to date explain only a small fraction of heritability. To identify novel susceptibility variants for CAD and confirm those previously(More)
The aims of this study were to quantify the angle and placement of an anterior cruciate ligament (ACL) grafted with a single incision ACL reconstruction technique using postoperative magnetic resonance imaging (MRI), and to compare the results with those with a native ACL. Between February 1996 and May 2004, 96 consecutive patients, who had undergone(More)
PURPOSE The purpose of this study was to evaluate the clinical and magnetic resonance imaging (MRI) outcomes of nonoperative management of acute, isolated posterior cruciate ligament (PCL) injuries. METHODS From February 2001 to January 2008, 49 consecutive patients with acute (<4 weeks), isolated PCL injuries underwent nonoperative treatment with cast(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 Recently, variations of the remnant bundle preservation technique, including selective bundle reconstruction and preservation of the anterior cruciate ligament tibial remnant, have produced good outcomes. The authors chose to investigate whether remnant bundle preservation in anterior cruciate ligament reconstruction would affect the remodeling(More)
BACKGROUND Longitudinal tears of the medial meniscus posterior horn (MMPH) are commonly associated with a chronic anterior cruciate ligament (ACL) deficiency. Many studies have demonstrated the importance of the medial meniscus in terms of limiting the amount of anterior-posterior tibial translation in response to anterior tibial loads in ACL-deficient(More)
The anterior cruciate ligament (ACL) surgical technique via a 5-strand hamstring tendon autograft is designed with a conventional single-bundle reconstruction that has shown favorable results and an additional posterolateral (PL) bundle reconstruction. The conventional single-tunnel technique is performed for the tibial tunnel, and the double-tunnel(More)
The objective of this prospective randomized controlled trial was to assess the efficacy and safety of simultaneous application of tranexamic acid and indirect factor Xa inhibitor following total knee arthroplasty (TKA). Seventy-two primary osteoarthritis patients undergoing unilateral TKA using fondaparinux as a basic thromboprophylaxis were randomized to(More)
PURPOSE To evaluate functional results and knee stability after tensioning of remnant posterior cruciate ligament (PCL) with anterolateral (AL) bundle reconstruction and posterolateral corner (PLC) reconstruction in chronic PCL and PLC injuries. METHODS Between March 2001 and March 2007, 95 patients with chronic PCL injuries combined with PLC injuries(More)
BACKGROUND Because of the anatomic and biomechanical differences between the lateral and medial menisci, it is believed that the indications, combined injuries, techniques, and outcomes of the 2 meniscus allograft transplantation (MAT) procedures may be different. HYPOTHESIS Medial meniscus transplantation (medial group) usually combines concomitant(More)
