“…They can communicate or not with the joint cavity [7][8][9]. A variety of disorders such as overuse [10], trauma [11], infection, hemorrhage, arthropathy, internal joint derangement, villonodular synovitis [12][13][14], and synovial osteochondromatosis [15] may cause the accumulation of fluid within the bursae and thickening of the synovia, allowing visualization on sonography. While the role of magnetic resonance imaging is widely described in the medical literature [1][2][3], the role of ultrasonography is poorly understood [4][5][6].…”

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.

“…Recurrence is frequent after partial synovectomy; hence, total synovectomy has been suggested as the preferred treatment. 12 In this patient complete removal of loose bodies was done anterior to the knee joint, Complete removal of diseased synovium was ensured to reduce chances of recurrence. Post-operative management includes a progressive range of motion exercise and strengthening of peri-articular muscle groups.…”

Synovial chondromatosis: a rare cause of knee pain and swelling

2020

View full text Add to dashboard Cite

<p>Synovial chondromatosis (SC) is a rare, benign, metaplastic, monoarticular disorder of synovial membrane and bursae of large joints. It commonly affects the large joints such as the knee, hips, wrist, ankle and shoulder. Here we report a case of SC of right knee in a 60-year-old female presenting with chief complaints of pain, swelling, restriction of movement in right knee for 1 year after a fall at home. X-ray of right knee revealed multiple calcified loose bodies. The final diagnosis was established by correlating radiologic findings with the histopathology of the excised specimen. Patient was successfully treated by open partial synovectomy of knee using anterior approaches in a single step procedure.</p>

Hoffa’s fat pad abnormalities, knee pain and magnetic resonance imaging in daily practice

et al. 2016

View full text Add to dashboard Cite

Hoffa’s (infrapatellar) fat pad (HFP) is one of the knee fat pads interposed between the joint capsule and the synovium. Located posterior to patellar tendon and anterior to the capsule, the HFP is richly innervated and, therefore, one of the sources of anterior knee pain. Repetitive local microtraumas, impingement, and surgery causing local bleeding and inflammation are the most frequent causes of HFP pain and can lead to a variety of arthrofibrotic lesions. In addition, the HFP may be secondarily involved to menisci and ligaments disorders, injuries of the patellar tendon and synovial disorders. Patients with oedema or abnormalities of the HFP on magnetic resonance imaging (MRI) are often symptomatic; however, these changes can also be seen in asymptomatic patients. Radiologists should be cautious in emphasising abnormalities of HFP since they do not always cause pain and/or difficulty in walking and, therefore, do not require therapy.Teaching Points• Hoffa’s fat pad (HFP) is richly innervated and, therefore, a source of anterior knee pain.• HFP disorders are related to traumas, involvement from adjacent disorders and masses.• Patients with abnormalities of the HFP on MRI are often but not always symptomatic.• Radiologists should be cautious in emphasising abnormalities of HFP.
