Abstract

Introduction:The role of popliteal cysts and subgastrocnemius bursitis in knee joint homeostasis is uncertain. The aim of this study is to describe cross-sectional associations between popliteal cysts, subgastrocnemius bursitis, knee symptoms and structural abnormalities in older adults.Methods:A cross-sectional sample of 900 randomly-selected subjects (mean age 63 years, 48 female) were studied. Knee pain, stiffness and dysfunction were assessed by self-administered Western Ontario McMaster Osteoarthritis Index (WOMAC) questionnaire. Radiographic knee osteophyte and joint space narrowing (JSN) were recorded. Magnetic resonance imaging (MRI) was utilized to assess popliteal cysts, subgastrocnemius bursitis, cartilage defects and bone marrow lesions (BMLs).Results:Popliteal cysts were present in 11.7 and subgastrocnemius bursitis in 12.7 of subjects. Subgastrocnemius bursitis was more common in those with popliteal cyst (36.2 versus 9.7 , P
