Cystic lesions linked to OA knee abnormalities

Baker’s cysts and bursitis are linked to increased osteoarthritic knee symptoms and abnormalities but it is not yet clear if they are cause or effect, a new Tasmanian study finds

The authors assessed knee pain, stiffness and dysfunction in 900 randomly selected Tasmanians aged 50 to 79, then performed knee radiography and MRI to check for cystic and bone marrow lesions as well as cartilage defects.
