Objective To evaluate the use of ultrasound for the diagnosis of knee bursitis. Materials and methods One-hundred and fifty-eight patients who, from May 2013 to May 2014, had an ultrasound examination of the knee and magnetic resonance imaging (MRI) of the knee during the following month were eligible for the study. The exams were reviewed by two musculoskeletal radiologists with 20 years of experience. Results Of these patients, 15 (7 men, 8 women) had bursitis, while 143 (76 men, 67 women) had no bursitis. In evaluating knee bursitis, US, when compared to MRI, correctly identified 13 out of 15 cases of bursitis, showing a sensitivity of 86.67 %, specificity 100 %, and K index of 0.92. Particularly in the suprapatellar bursa, ultrasound showed bursitis in 5 cases versus 7 by MRI (sensitivity of 71.4 %, specificity of 100 %, and K index of 0.82). Conclusion Ultrasound can be used as a valuable tool for the evaluation of bursitis of the superficial bursae in patients who cannot undergo MRI.Keywords Ultrasound Á Magnetic resonance imaging Á Knee Á Bursitis Á Knee bursitis Riassunto Obiettivo Valutare l'utilizzo dello studio ecografico nella diagnosi delle borsiti del ginocchio. Materiali e metodi Nello studio sono stati considerati centocinquantotto pazienti tra Maggio 2013 e Maggio 2014 valutati con esame ecografico del ginocchio che sono stati rivalutati con Risonanza Magnetica entro un mese dalla valutazione ecografica. Gli esami radiologici sono stati esaminati da due radiologi con 20 anni di esperienza in campo muscolo scheletrico. Risultati All'interno del gruppo di pazienti in studio 15 (7 uomini, 8 donne) hanno presentato diagnosi di borsite, mentre 143 pazienti (76 uomini, 67 donne) hanno presentato un esame negativo. L'ecografia comparata alla Risonanza magnetica nella valutazione delle borsiti del ginocchio ha evidenziato 13 casi su 15, mostrando una sensibilità del 86.67 %, specificità del 100 % e indice K di 0.92. In particolare a livello della borsa sovra patellare, l'ecografia ha mostrato la presenza di borsite in cinque casi, rispetto ai 7 pazienti della Risonanza Magnetica (Sensibilità 71.4 %, specificità 100 % e indice K 0.82). Conclusioni L'ecografia può essere utilizzata come strumento efficace nella valutazione delle borsiti delle borse superficiali nei pazienti che non possono essere sottoposti a valutazione con Risonanza Magnetica.

“…The knee bursae are numerous and, in the absence of pathological changes, rarely apparent on MR imaging [ 3 ]. The knowledge of the locations of synovial bursae is important since in pathological conditions, they may become apparent and a cause for misdiagnosis or diagnostic uncertainty [ 2 ]. The classifi cation of the bursae is made on their anatomic location (Table 8.1 ).…”

The anterior and posterior cruciate ligaments, menisci, and the infrapatellar fat pad are located "extrasynovially" which means that they are located outside the abovementioned synovial compartments.…”

“…The suprapatellar recess or bursa is a pouch formed by the articular capsule of the knee possessing its own synovial lining (8), while the medial parapatellar and lateral parapatellar recesses are extensions thereof in the medial parapatellar and lateral parapatellar areas, respectively. The parapatellar recesses are recommended among the standard scans of the knee in the guidelines on the use of sonography in rheumatology (6) and have been utilized for individual measurement of fluid volume in the knee by several investigations utilizing ultrasound, as well as other imaging modalities (9 -12).…”

Objective. Various methods are utilized in daily practice to obtain optimal information on effusion in the knee. Our aim is to investigate which scanning position provides the best information about synovial fluid in the knee by using ultrasound and to evaluate the magnitude of difference for measuring synovial fluid in 3 major recesses (suprapatellar, medial parapatellar, and lateral parapatellar) of the knee according to various degrees of flexion. Methods. Sonographers in 14 European
