Clinical Trial
Ultrasonographic assessment of Baker's cysts after intra-articular corticosteroid injection in knee osteoarthritis.
To assess sonographic changes in Baker's cysts (BCs) of patients with knee osteoarthritis after a single intra-articular corticosteroid injection. ⋯ In this series of osteoarthritis patients, injection of corticosteroids inside the knee joint accounted for a reduction in BC dimensions as well as cyst wall thickness. Sonography can be used not only for the diagnosis of BCs but also to monitor response to therapy.
