BACKGROUND Tibial fixation is more problematic than femoral fixation in anterior cruciate ligament reconstruction. HYPOTHESIS There is no difference in initial fixation strength among hamstring tendon graft tibial fixation devices. STUDY DESIGN Randomized experimental study. METHODS Each of six devices used to fix 120 quadrupled human semitendinosus-gracilis tendon grafts into porcine tib...

INTRODUCTION Due to advances in technology, segmental gait analysis of the foot is now possible and can elucidate hindfoot deformity in persons with posterior tibial tendon dysfunction (PTTD). This study evaluated the motion of the hindfoot and ankle power following surgical reconstruction for PTTD utilizing a segmental foot model during gait. MATERIALS AND METHODS Twenty patients who underwe...

OBJECTIVE Knee ligament injuries frequently cause devastating impairment to the injured. In car-pedestrian impact accidents, lateral-medial shear displacement is one of principal mechanisms of knee ligament injuries. The current study aims to investigate injury thresholds of knee ligaments under lateral-medial shear loading to improve pedestrian safety. METHODS Ten isolated human knee joints ...

  Background: Patients with an anterior cruciate ligament-deficient varus-angulated knee may need not only an isolated high tibial osteotomy (HTO), but also an additional anterior cruciate ligament reconstruction (ACLR). A number of prospective clinical trials have been published considering the combination of HTO and ACL reconstruction. Our aim was to investigate whether one-stage combined HTO...

PURPOSE The aim of this study was to determine the outcomes of bursoscopic ossicle excision in young and active patients with unresolved Osgood-Schlatter disease. METHODS This retrospective study included 18 male military recruits. A direct bursoscopic ossicle excision was performed using low anterolateral and low anteromedial portals. Outcomes were evaluated using the Lysholm knee score, pai...

OBJECTIVE To assess the correlation between five anthropometric parameters and the distance from tibial tuberosity to medial malleolus in 100 volunteers. METHODS Six anthropometric parameters were measured in 50 male and 50 female medical students using a metallic scale: medial knee joint line to ankle joint line (K-A), medial knee joint line to medial malleolus (K-MM), tibial tuberosity to a...

Fractures of the tibial tuberosity are uncommon injuries that mainly occur in 14 to 16 year-old adolescents involved in sports activities. The mechanism of injury is related to jumping while practicing sports. This retrospective study presents the outcome of fractures of the tibial tuberosity in a series of 18 adolescent soccer players treated with the same surgical technique in one center. The...

Large, engaging Hill-Sachs lesions can cause recurrent glenohumeral instability following Bankart repair of torn anterior capsulolabral structures. We offer a novel technique for correcting the posterolateral humeral head defect without significantly altering normal anatomic structures. The glenohumeral joint is exposed via a deltopectoral approach. After the defect geometry is appreciated by d...

A 13-year-old boy sustained an injury to both knees upon landing after a forceful jump in a soccer game. Plain radiography and magnetic resonance imaging demonstrated bilateral distal patellar tendon avulsions without fracture of the tibial tuberosities and the physes. To our knowledge, this particular injury has not been previously described in the literature. Open surgeries and internal fixat...
