  1. Dependent variable: presence of pain, stiffness or dysfunction (yes versus no). Independent variable: subgastrocnemius bursitis or popliteal cyst, per grade. *Adjusted for age, sex, body mass index, disease status, and radiographic osteoarthritis; #further adjusted for effusion; further adjusted for bone mass lesions and cartilage defects. Data in bold denote statistically significant results. WOMAC, Western Ontario McMaster Universities osteoarthritis index.
