Implication

Cross-sectional study evaluates ultrasound for knee osteoarthritis severity in patients experiencing knee pain, suggesting potential as an alternative to radiographs.

Key Points

The aim is to assess the effectiveness of ultrasound in measuring joint space width for grading knee osteoarthritis severity during weight-bearing conditions.
Cross-sectional study involving 256 patients with knee pain and suspected knee osteoarthritis.
Participants underwent standing weight-bearing ultrasound and radiography of the knee at various flexion angles.
Reliability of measurements was analyzed using statistical methods including kappa coefficients and correlation analysis.
Ultrasound joint space width measurements at 45° flexion showed higher diagnostic efficacy than at 20° flexion (AUC 0.839 vs. 0.825).
Significant decreasing trends in joint space width and increasing trends in osteophyte height were observed with higher Kellgren-Lawrence grades.
Moderate to excellent interrater reliability indicated consistency in ultrasound evaluations (ICC 0.54–0.92).
