Pain in bilateral knee osteoarthritis - correlations between clinical examination, radiological, and ultrasonographical findings.

Aims: The aim of the study was to evaluate the correlations between clinical symptoms (pain), physical examination, ultrasound (US), and radiological findings in patients with bilateral knee osteoarthritis (OA).

Material And Methods: Knee pain was appreciated during medial and lateral palpation of each knee joint and using visual analogue scale (VAS) and The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). US evaluation (osteophytes, meniscal protrusion, synovial fluid, femoral hyaline cartilage thickness) and radiological assessment (osteophytes, femoral-tibial space, Kellgren-Lawrence [K-L] score, enthesopathies) were performed by two examiners blinded to the clinical results and to each other.
