A síndrome anserina

Abstract

Dor no joelho é uma condição comum na clínica diária e a patologia anserina, também conhecida como pata de ganso, tem sido considerada uma das principais causas. O diagnóstico tem sido realizado de maneira eminentemente clínica, o que tem gerado equívocos. Os pacientes queixam-se tipicamente de dor na parte medial do joelho, com sensibilidade na porção ínferomedial. Estudos de imagem têm sido realizados para esclarecer se tais pacientes possuem bursite, tendinite ou ambos os distúrbios na região conhecida como pata de ganso. Entretanto, o defeito estrutural responsável pelos sintomas permanece desconhecido, motivo pelo qual preferimos intitular como "Síndrome Anserina". O diabetes mellitus é um fator predisponente bem reconhecido. O sobrepeso e a osteoartrite de joelho parecem ser fatores adicionais de risco, contudo, seus papéis na gênese da moléstia ainda não são bem entendidos. O tratamento atual inclui anti-inflamatório, fisioterapia e infiltração de corticoide, com evolução muito variável, que oscila entre 10 dias e 36 meses. A falta de conhecimento sobre a etiofisiopatologia e dados epidemiológicos exige futuros estudos para esse frequente e intrigante distúrbio.Palavras-chave: bursite anserina, tendinite da pata de ganso, síndrome da bursite/tendinite anserina, pata de ganso.

Fluid signal changes around the knee on MRI are associated with increased volumes of subcutaneous fat: a case-control study

“…Numerous studies have demonstrated the role obesity plays in the development of osteoarthritis [1–3], cartilage defects [4–7], bone marrow lesions [6–8], pes anserine syndromes [9], and patello-femoral osteoarthritis [10]. These changes are largely attributed to a combination of increased load and altered joint biomechanics [11].…”

Pes Anserinus Syndrome Caused by Osteochondroma in Paediatrics: A Case Series Study

“…The incidence of pes anserinus syndrome is higher in women who are overweight and 50-80 years old, especially if they also have osteoarthritis of the knees, valgus deformities or pes planus [7, 10, 12]. A second etiology includes osteochondroma, as well as trauma, retraction of posterior thigh muscles, damage to the medial meniscus, infection, and foreign body reaction [10, 14].…”

A second etiology includes osteochondroma, as well as trauma, retraction of posterior thigh muscles, damage to the medial meniscus, infection, and foreign body reaction [10, 14]. The differential diagnosis of pes anserinus syndrome considers lesions with pain infero-medial to the knee joint, such as the medial meniscus; osteoarthritis of the medial compartment of the knee; lumbar radiculopathy; lesions in the medial collateral ligament; and insufficiency fractures [10, 15].…”

“…Pain in the pes anserinus region can be diagnosed as pes anserinus syndrome or anserine bursitis [7]. Although the term “anserine bursitis” is commonly used, the structure responsible for the symptoms is not identified, and little is known about the pathology [10]. The diagnosis of pes anserinus syndrome is based on clinical manifestations marked by spontaneous medial knee pain on climbing or descending stairs, tenderness at the pes anserinus insertion and occasional local swelling [7, 8, 11].…”

The incidence of pes anserinus syndrome is higher in women 50-80 years of age than in younger women or in men [10, 12]. Osteochondroma causing pes anserinus syndrome is a rare condition in the general population [13].…”
