Popliteal (Baker’s) Cyst: Pathogenesis and clinical findings • Idiopathic • Meniscal Lesions • Osteoarthritis • Rheumatoid Arthritis Notes: • Popliteal cysts are rare in children and are often idiopathic and asymptomatic with no communication with the joint, therefore sometimes we consider aspiration. • Popliteal cysts in adults are often associated with intra-articular knee lesions. Therefore, we manage the underlying joint disease. We never aspirate/ excise the Baker's cyst with underlying joint disease as it will just come back.
