PURPOSE To evaluate the effectiveness of all-inside repair of posterior lateral meniscus root full-thickness tears with preoperative and postoperative magnetic resonance imaging (MRI) and to propose a system of classifying posterior lateral meniscus root tears. METHODS From June 2003 to March 2007, 27 (6.95%) of a consecutive series of 388 anterior(More)
BACKGROUND During rotator cuff repair, biceps tendon lesions are frequently encountered. However, there is still controversy about optimal treatment for these lesions. PURPOSE To compare the results of tenotomy and suture anchor tenodesis prospectively. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS From January 2006 to June 2007, 90(More)
PURPOSE To evaluate by second-look arthroscopy the clinical results of arthroscopic all-inside sutures with hook using 2 posteromedial portals for medial meniscus posterior horn (MMPH) tears in patients who underwent concurrent anterior cruciate ligament (ACL) reconstruction. TYPE OF STUDY Case series. METHODS From May 1997 to June 2001, 78 knees(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)
Transection injury (complete radial tear, root tear) in the posterior horn of medial meniscus will lead to loss of hoop strain, extrusion of the meniscus and early degenerative changes. The posterior horn of medial meniscus is amenable to repair due to its good blood supply and repair is the procedure of choice for these injuries. In cases of transection of(More)
PURPOSE The purpose of this study was to compare the clinical outcomes and the retear rates of arthroscopic single-row (SR) and double-row (DR) suture anchor repair in 2- to 4-cm rotator cuff tears. METHODS From 2005 to 2007, 71 patients with a 2- to 4-cm rotator cuff tear (proven by arthroscopy) were prospectively randomized to SR and DR repair groups.(More)
The aim of this study is to report the arthroscopic subjective findings of reconstructed anterior cruciate ligament (ACL) with good clinical outcome. Graft used for reconstruction was either patella bone-tendon-bone (PBTB) autograft or hamstring tendon [quadrupled semitendinous and gracilis tendon (QSGT)] autograft. From March 1997 to September 2003, among(More)
This paper reports the clinical outcome of the arthroscopic reduction and pull-out suture technique in acute and chronic displaced tibial spine anterior cruciate ligament (ACL) avulsion fractures. Between April 1997 and December 2000, 14 patients received an arthroscopic reduction and pull-out suturing of displaced tibial spine fractures (ACL avulsion(More)
The purposes of this study were to report degenerative changes that coexist with a symptomatic torn discoid lateral meniscus in adults and to analyze the factors associated with the accompanied degenerative changes. From 1997 to 2008, 329 knees in the 305 patients were included. Associations between the status of the meniscus and the coexisting degenerative(More)
PURPOSE To evaluate the optimal number of additional half-hitches needed to achieve optimal knot-holding capacity (KHC) of lockable sliding knots. TYPE OF STUDY Mechanical testing study. METHODS Four configurations of arthroscopic knots (Duncan loop, Field knot, Giant knot, and SMC knot) were tested for their knot-holding capacity. For each knot(More)
