AB  - BACKGROUND: Quantitative measurement of knee joint effusion by ultrasonography 
      has not been well established; however, a categorical measurement (e.g., a 
      >/=4-mm-deep suprapatellar pouch) is recommended. Therefore, the current study 
      aimed to elucidate the association between symptoms of knee osteoarthritis (OA) 
      and the quantitative measurement of suprapatellar effusion by ultrasonography. 
      METHODS: One hundred twenty-seven volunteers participated (31 men and 96 women; 
      mean age: 68.3 +/- 9.8 years; body mass index: 23.2 +/- 3.0 kg/m(2)). The 
      Kellgren-Lawrence grades (KLGs) of both knees were assessed; all subjects had 
      definitive osteoarthritic change (KLG >/=2) in both knee joints. Joint effusion was 
      evaluated using an ultrasound probe, which was placed longitudinally on the 
      suprapatellar pouch, and we determined the area (mm(2)) of the echo-free space. 
      Then we summed the effusion area of both knees. All subjects answered the knee 
      injury and osteoarthritis outcome scale (KOOS) questionnaire. Multiple linear 
      regression analysis was conducted to elucidate the association between the summed 
      value of the knee effusion area and the KOOS subscales, which were adjusted by 
      age, sex, body mass index, and KLG. RESULTS: Of 254 knees, 180 were KLG 2, 57 
      were KLG 3, and 17 were KLG 4. The multiple regression models showed that the 
      quantitative knee effusion area significantly correlated with the following KOOS 
      subscales: pain (B = -0.057; beta = -0.253; P = 0.002), symptom (B = -0.053; 
      beta = -0.251; P = 0.002), sport and recreation (B = -0.069; beta = -0.205; P = 0.007), 
      and quality of life (B = -0.083; beta = -0.276; P = 0.001). CONCLUSION: In this 
      cross-sectional study, the quantitative measurement of suprapatellar effusion by 
      ultrasonography was associated with symptoms of radiographic knee OA.
