Background: The intraarticular (IA) injection has become popular for the management of the osteoarthritic knee without an effusion. The success rate of IA injection would be better if it was able to be visually confirmed. We hypothesized that an anterolateral approach, which targets the synovial membrane of the lateral condyle using ultrasound, would provide an equivalent alternative to the anterolateral approach, targeting the synovial membrane of the medial condyle for IA injection of the knee...

Estimates of muscle tissue composition may have greater prognostic value than lean body mass levels regarding health-related outcomes. Ultrasound provides a relatively low cost, safe, and accessible mode of imaging to assess muscle morphology. The purpose of this study was to determine the construct validity of muscle echogenicity as a surrogate measure of muscle quality in a sample of older, predominantly African American (AA) participants. We examined the association of rectus femoris echogenicity with mid-thigh computed tomography (CT) scan estimates of intra- and intermuscular adipose tissue (IMAT), basic metabolic parameters via blood sample analysis, muscle strength, and mobility status...

We report a case of a 12-year-old boy who presented with infrapatellar pain, with subsequent diagnosis of traction apophysitis of the knee (Sinding-Larsen-Johansson disease). Conventional radiographs are frequently reported with no significant findings in the acute setting, leading to ultrasound as the modality of choice for diagnostic efficacy of apophyseal traction injuries in young athletes. Sinding-Larsen-Johansson disease has a 2%-5% incidence in children aged 10-15 years, with the most common cause related to sporting activities related to jumping...

Determining the clinical impact of imaging exams at the enterprise level is problematic, as radiology reports historically have been created with the content meant primarily for the referring provider. Structured reporting can establish the foundation for enterprise monitoring of imaging outcomes without manual review providing the framework for assessment of utilization and quality. Ultrasound (US) for deep vein thrombosis evaluation (DVT) is an ideal testbed for assessing this functionality. The system standard template for Doppler US for extremity venous evaluation for DVT was updated with a discrete fixed picklist of impression options and implemented system wide...

Tophaceous deposits in lumbar spine is considered a rare condition. We report the case of a 44-year-old patient with low back pain and radiculopathy. Radiographs revealed lytic spondylolisthesis in L5. Magnetic resonance imaging showed hypointense signal on T1 and a heterogeneous signal on T2 located in the L4-L5 interspinous space and in the left facet joint that invades left neuroforamen. The left knee ultrasound showed «double contour» of the medial femoral condyle. Decompressive laminectomy with arthrodesis at the level of L5-S1 was performed...

Ruptures of the extensor mechanism of the knee joint are rare but disabling injuries. Injuries occur on the basis of degeneration or acute trauma. The understanding of anatomy and biomechanical function plays an essential role for choosing the right diagnostic methods and initiating successful treatment. Besides clinical examination ultrasound is a cost efficient primary diagnostic measure. Additional MRI can be beneficial for partial tears or chronic ruptures. Non-operative treatment is suitable for minor partial ruptures with sustained function...

Infrapatellar branches of the saphenous nerve are always present at the anteromedial aspect of proximal tibia. Iatrogenic injury to these branches is a known consequence of knee surgery, be it an arthroscopic portal, harvesting of a hamstring or bone-patellar tendon-bone anterior cruciate ligament graft, or opening wedge opening high tibial osteotomy. Their anatomic course can be variable. High-resolution ultrasound may provide an improved diagnostic tool for better identification.

INTRODUCTION: Examination of the mechanical behavior of the hamstrings when acting as antagonists provides information about loading of this muscle group and its role for joint stability during forceful quadriceps contractions. The aim of this study was to quantify biceps femoris long head fascicle length (FL), angle of pennation (PA) and distal tendon/aponeurosis strain during maximum voluntary contraction efforts of the knee extensors using real-time ultrasound. METHODS: Fourteen participants performed passive joint movements and maximum voluntary knee extension and flexion efforts of the knee flexors at 0°, 45° and 90° of knee flexion...

PURPOSE: This study aimed to assess muscle coactivation in quadriceps and hamstring muscles using ultrasound shear wave elastography. METHODS: During maximal voluntary isometric contractions (MVC), both myoelectrical activity and shear modulus of antagonist muscles were measured (i.e., rectus femoris, vastus lateralis and vastus medialis during knee flexions and semitendinosus, semimembranosus and biceps femoris long head during knee extensions). To account for changes induced by inevitable joint rotation during MVC, the shear modulus values were compared to those measured at the same knee angle during a passive cycle...
