“…Baker's cyst was the most frequently detected cystic lesion in the present study, and in consistency with multiple previous reports, it was more common in oldaged males (8,21,22) . The progressive degenerative thinning out or opening of the joint capsule with aging could explain our results (23) .…”

Background: Knee cysts are common clinical findings and MRI is frequently used in their assessment. However, compared to ultrasound (US), MRI is expensive and of limited availability. The objective of the current study is to compare the efficacy of US and MRI in the detection and characterization of benign cysts and cyst-like lesions in and around the knee with a gold standard correlation. Patients and methods. Patients with benign cysts or cyst-like lesions in or around the knee were included. All patients underwent MRI followed by US of the affected knee. Based on the gold-standard correlation, the diagnostic performances of both imaging modalities in each type of cystic lesion were quantified and compared. Finally, the agreement between each imaging modality and the gold standard and between both modalities was calculated.Results. The diagnosis of benign knee cystic lesions was confirmed in 96 patients. Baker's cyst was the most frequent followed by meniscal and ganglion cysts. There was a predominance of males, young and middle-aged, and right knee affection. MRI showed insignificantly higher accuracies (100%, 100%, and 99%) than those of US (97%, 95.8%, and 97%) in diagnosing Baker's, meniscal, and ganglion cysts (p>0.05). The agreement between MRI and US was substantial regarding the detection of ganglion cysts (k=0.75), and almost perfect regarding Baker's and meniscal cysts (k=0.96 and 0.90). Conclusion.US is a time-and cost-effective, easily available, and non-invasive imaging modality with comparable accuracy to MRI in diagnosing benign knee cysts and cyst-like lesions. However, US is of limited performance as regards small parameniscal and intra-articular ganglion cysts.

“…Acerca da formação do cisto em si, acredita-se que ocorra a junção de diversos fatores que propiciam o acúmulo de líquido sinovial entre o músculo semimembranáceo e a cabeça medial do músculo gastrocnêmio. Dentre os principais, destacam-se o sequestro de líquido sinovial na fossa poplítea por um efeito de válvula entre a junta e o cisto, controlado pela flexão e extensão do joelho, a variação pressórica intra-articular conforme o movimento da articulação, responsável por ajudar na formação e no preenchimento cístico, e o aumento da bursa dos músculos gastrocnêmio e semimembranáceo resultante de pequenos traumas oriundos da contração muscular (Li et al, 2018;Maximiliano et al, 2018;Samhan et al 2021). Do ponto de vista anatomopatológico e histopatológico, o cisto de Baker é classificado como uma entidade ganglionar coberta por células mesoteliais e fibroblastos.…”

Introdução: O cisto de Baker, também chamado de cisto poplíteo, é uma condição osteomuscular que desenvolve em associação com outras doenças inflamatórias e degenerativas, resultando em um quadro álgico importante. Objetivo: O presente estudo teve como objetivo avaliar os aspectos clínicos, epidemiológicos e fisiopatológicos do cisto de Baker, alicerçando a construção do conhecimento com base em relatos de casos e no conhecimento sedimentado na literatura. Materiais e Métodos: Trata-se de uma revisão integrativa de literatura acerca das características clínicas gerais sobre o cisto de Baker. Utilizou-se a estratégia PICO para a elaboração da pergunta norteadora. Ademais, realizou-se o cruzamento dos descritores “Cisto de Baker”; “Cisto Poplíteo”; “Tratamento”, nas bases de dados National Library of Medicine (PubMed MEDLINE), Scientific Eletronic Library Online (SCIELO), Ebscohost, Google Scholar e Biblioteca Virtual de Saúde (BVS). Resultados e Discussão: Os artigos demonstraram que a ocorrência do cisto de Baker está associada com doenças articulares degenerativas e inflamatórias, sendo mais prevalente em indivíduos maiores de 40 anos. Também foram discutidos os mecanismos fisiopatológicos para o seu desenvolvimento, bem como as principais manifestações clínicas e as formas diagnósticas. Conclusão: O cisto de Baker é uma condição benigna que cursa com dor articular, edema e limitação do movimento. O diagnóstico é eminentemente clínico e complementado por exames de imagem. O tratamento engloba medidas de analgesia que podem evoluir até para procedimentos cirúrgicos, de acordo com a gravidade do caso.

“…19 Because of the functional valve mechanism, fluid in the knee joint is constantly drained into Baker cysts, which results in decreased fluid in the anterior knee. 20,21 Therefore, in adult patients with Baker cysts, lack of fluid in the suprapatellar recess cannot rule out knee effusion.…”

Objective: A review of the anatomy of the synovial recesses of the knee is important to better understand the different effusion presentations, update the diagnosis criteria of knee effusion based on the measured synovial recesses and discuss the differentiation of some effused recesses from other lesions around the knee. Method: This review focuses on the anatomy of the synovial recesses of the knee and classifies them into three groups (anterior, parameniscal, and posterior recesses), as well as provides an overview on the etiology of knee effusion, its sonographic detection, and diagnosis criteria. Results: Knee effusion is a very common pathological finding in sonography of the knee. The unique joint structure of the knee provides the possibility to host complex synovial recesses. Fluid in some of the synovial recesses is valuable for the diagnosis of knee effusion, while in certain situations, some recesses may impose diagnostic uncertainty. Knowledge of these synovial recesses is essential to avoid diagnostic pitfalls. Conclusion: This review provides an important discussion of the differentiation of some recesses effusions from other lesions around the knee.
