“…Other studies added that the disc was surrounded by hard tissues of the condyle and temporal bone. Therefore, significant difference exists in the acoustic properties of the disc and its surrounding structures, resulting in a considerable reflection of ultrasound waves and formation of sharp image [11][12][13][14].…”

“…Applications of higher frequency ultrasound probe (18 MHz) and advancements in ultrasound probe technology continue; more detailed imaging and improvement in tissue differentiation will improve the image quality and may contribute to a better diagnosis [11][12][13][14]. Application of three-dimensional ultrasound examinations [31] increases the diagnostic validity of ultrasound in diagnosis of sideway as well as the anterior disc displacement and improves the relationship of the articular disc with bony condyles.…”

Purpose To assess pattern of articular disc displacement in patients with internal derangement (ID) of temporomandibular joint (TMJ) with ultrasound. Materials and methods Prospective study was conducted upon 40 TMJ of 20 patients (3 male, 17 female with mean age of 26.1 years) with ID of TMJ. They underwent highresolution ultrasound and MR imaging of TMJ. The MR images were used as the gold standard for calculating sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (PLR), and negative likelihood ratio (NLR) of ultrasound for diagnosis of anterior or sideway displacement of the disc. Results The anterior displaced disc was seen in 26 joints at MR and 22 joints at ultrasound. The diagnostic efficacy of ultrasound for anterior displacement has sensitivity of 79.3 %, specificity of 72.7 %, accuracy of 77.5 %, PPV of 88.5 %, NPV of 57.1 %, PLR of 2.9 and NLR of 0.34. The sideway displacement of disc was seen in four joints at MR and three joints at ultrasound. The diagnostic efficacy of ultrasound for sideway displacement has a sensitivity of 75 %, specificity of 63.6 %, accuracy of 66.7 %, PPV of 42.8, NPV of 87.5 %, PLR of 2.06, and NLR of 0.39. Conclusion We concluded that ultrasound is a non-invasive imaging modality used for assessment of anterior and sideway displacement of the articular disc in patients with ID of TMJ.Riassunto Scopo Valutare i pattern della dislocazione del disco articolare nei pazienti con squilibrio interno (ID) dell'articolazione temporo-mandibolare (ATM) con l'ecografia. Materiale e metodi E' stato condotto uno studio prospettico su 40 ATM di 20 pazienti (3 maschi, 17 femmine, con età media di 26,1 anni) con ID della TMJ. Tutti sono stati sottoposti ad ecografia ad alta risoluzione e RM della TMJ. La RM è stati utilizzata come il gold standard per il calcolo di sensibilità, specificità, accuratezza, valore predittivo positivo (PPV), valore predittivo negativo (NPV), rapporto di probabilità positivo (PLR) e rapporto di probabilità negativo (NLR) dell'ecografia nella la diagnosi di dislocazione anteriore o lateralmente del disco. Risultati Il disco appariva dislocato anteriormente in 26 ATM con la MR e in 22 con l'ecografia. L'efficacia diagnostica dell'ecografia nella diagnosi di dislocazione anteriore aveva sensibilità del 79,3 %, specificità del 72,7 %, accuratezza del 77,5 %, valore predittivo positivo del 88,5 %, NPV di 57,1 %, PLR di 2,9 e NLR di 0,34. Il dislocamento laterale del disco è stata osservato in 4 casi con MR e 3 con ecografia. L'efficacia diagnostica dell'ecografia per lo spostamento laterale aveva sensibilità del 75 %, specificità del 63,6 %, accuratezza del 66,7 %, PPV di 42,8, NPV di 87,5 %, PLR di 2.06 e NLR di 0,39. Conclusioni Abbiamo concluso che l'ecografia è una metodica di imaging non invasiva che può essere utilizzata per la valutazione delle dislocazioni anteriori e laterali del disco articolare nei pazienti con ID di TMJ.

The aim of this work was to assess the reproducibility of ultrasound findings of knee osteoarthritis and to correlate ultrasound findings with Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Prospective study was conducted upon 80 patients (56 F, 24 M; mean age 57 years) with primary osteoarthritis of knee joint. All patients underwent clinical assessment with calculation of WOMAC and high-resolution ultrasound of the knee joint. The ultrasound images were analyzed for cartilage thinning, osteophytes, synovial effusion, synovial proliferation, popliteal cyst, and meniscal protrusion. Image analysis was performed by two readers and linear regression analysis was used to determine association of ultrasound findings with WOMAC. There was excellent inter-observer agreement of both readers for cartilage thinning (k = 0.99, P = 0.001), osteophytes (k = 0.94, P = 0.001), synovial effusion (k = 0.98, P = 0.001), synovial thickening (k = 0.96, P = 0.001), popliteal cyst (k = 1.00, P = 0.001), and meniscal protrusion (k = 0.86, P = 0.001). There was significant association of WOMAC with cartilage changes (t = 3.406, 3.302, P = 0.001), osteophytes (t = 3.841, 3.006, P = 0.001), and synovial effusion (t = 4.140 and 2.787, P = 0.05) of both readers. We concluded that ultrasound is a reproducible method for assessment of knee osteoarthritis and well correlated with WOMAC.

Ultrasound Detection of Patellar Fracture and Evaluation of the Knee Extensor Mechanism in the Emergency Department

Traumatic injuries to the knee are common in emergency medicine. Bedside ultrasound (US) has benefits in the rapid initial detection of injuries to the patella. In addition, US can also quickly detect injuries to the entire knee extensor mechanism, including the quadriceps tendon and inferior patellar ligament, which may be difficult to diagnose with plain radiographs. While magnetic resonance imaging remains the gold standard for diagnostic evaluation of the knee extensor mechanism, this can be difficult to obtain from the emergency department. Clinicians caring for patients with orthopedic injuries of the knee would benefit from incorporating bedside musculoskeletal US into their clinical skills set.
