PURPOSE The incidence of root tears in patients with spontaneous osteonecrosis of the knee has been studied, but the incidence of spontaneous osteonecrosis of the knee in patients with medial meniscus root tears has not. We assessed the latter incidence and evaluated the characteristics of medial meniscus root tears by comparing clinical status, the degree(More)
PURPOSE The aim of this study was to compare the clinical and radiological results of the wedge plate and locking plate systems in open-wedge high tibial osteotomy. METHODS Between 2007 and 2010, the wedge plate was used as the fixation device for osteotomy to treat a total of 67 patients; from 2009 to 2010, the locking plate was used in 19 patients.(More)
PURPOSE This study compared the clinical and radiologic outcomes of arthroscopic medial meniscus root refixation using the modified Mason-Allen stitch and simple stitches. METHODS The outcomes of 25 patients who underwent arthroscopic meniscus root refixation using the modified Mason-Allen stitch (M group) between June 2010 and January 2012 were compared(More)
BACKGROUND Recently, posterolateral corner (PLC) reconstruction techniques have been developed based on an anatomic study of cadaveric dissections. However, the best operative method for various anatomic reconstructions remains controversial. HYPOTHESIS The anatomic single fibular sling method for PLC reconstruction would be sufficiently strong to control(More)
PURPOSE To report on the results of 12 complete radial tears of the meniscus treated using arthroscopic inside-out repair with fibrin clots, the results showed good meniscal healing and excellent clinical outcomes. METHODS From 2007 to 2009, 12 patients with complete radial tears of the meniscus were treated by arthroscopic inside-out repair with fibrin(More)
A complete posterior medial meniscus root tear results in the inability to withstand hoop stress and requires the repair of the posterior medial meniscus root. Several techniques to repair the posterior medial meniscus root have been proposed, but most techniques are based on simple stitching. A modified Mason-Allen technique, recognized as a superior(More)
BACKGROUND The purpose of this study is to report a modified transtibial technique to approach the center of anatomical femoral footprint in anterior cruciate ligament (ACL) reconstruction and to investigate the accurate femoral tunnel position with 3-dimensional computed tomography (3D-CT) and radiography after reconstruction. METHODS From December 2010(More)
Damage to the medial meniscus root, for example by a complete radial tear, destroys the ability of the knee to withstand hoop strain, resulting in contact pressure increases and kinematic alterations. For these reasons, several techniques have been developed to repair the medial meniscus posterior root tear (MMPRT), many of which have shown complete healing(More)
BACKGROUND Recent studies have shown that lateral menisci have a higher healing potential and that they can be treated successfully without symptoms by being left in situ during anterior cruciate ligament (ACL) reconstruction. However, few studies have reported morphological results. HYPOTHESIS Stable posterior horn tears of the lateral meniscus left in(More)
BACKGROUND Numerous posterior cruciate ligament (PCL) reconstruction techniques have evolved and have revealed satisfactory outcomes; however, the optimal operative method for PCL reconstruction remains controversial. HYPOTHESIS Transtibial PCL reconstruction with a remnant preservation technique would result in successful clinical, radiological,(More)
