BACKGROUND Meniscus allograft transplantation (MAT) is useful for meniscus-deficient knees. Although meniscal extrusion is common after MAT, there is no consensus regarding the criteria for normal meniscal extrusion or the relationship between clinical and radiologic results. HYPOTHESIS Meniscal extrusion after MAT results in poor clinical, radiologic,(More)
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 To investigate the clinical, radiologic, and arthroscopic findings of pullout repair in medial meniscus root tear (MRT) and to compare the results of pullout repair and partial meniscectomy. METHODS This study enrolled 58 consecutive patients with medial MRT who underwent partial meniscectomy (M group, n = 28) or pullout repair (R group, n = 30)(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 The purposes of this study were to evaluate the effect on tibiofemoral contact mechanics of repair of the posterior root of the medial meniscus and the effect of meniscal allograft transplantation (MAT) with medial collateral ligament (MCL) release at different flexion angles. METHODS Ten fresh-frozen human cadaveric knees (five pairs) were used.(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)
BACKGROUND Medial meniscus posterior root tears (MMPRTs) lead to extrusion of the meniscus during weightbearing as well as loss of the ability of the meniscus to generate hoop stress. This loss of load-sharing ability leads to progressive arthritic changes. However, there have been no studies that correlate the correction of meniscus extrusion with clinical(More)
A complete radial tear of the meniscus posterior root, which can effectively cause a state of total meniscectomy via loss of hoop tension, requires that the torn root be repaired. Several methods have been used to repair medial meniscus posterior root tears, most of which are based on a simple stitch technique that is known to have stitch-holding strength.(More)
