Anatomy Imaging Treatment Options for Baker’s Cyst

Description: A Baker’s cyst is a synovial cyst that usually communicates with the knee joint by way of a slit-like opening, lined with synovium. Rausching and Lindgren in their study suggested 2 mechanisms for cyst formation. The primary cyst has an unilateral valvular connection and the secondary cyst communicates freely with the knee joint and contains synovial fluid of normal viscosity. Intrinsic intra-articular disorders causing excessive joint effusion and cyst may serve as a protective mechanism by reducing destructive pressure in the joint space
