OBJECTIVE: To determine the association between the severity of femoral condylar
cartilage erosion resulting from knee osteoarthritis (OA) by an ultrasonographic
grading system and the clinical symptoms and functions. DESIGN: Cross-sectional
study. SETTING: A tertiary center. PARTICIPANTS: Participants (N=101) with and
without subjective complaints of knee discomfort were consecutively enrolled.
Patients who had ever received knee arthroplasty, who had inflammatory arthritis,
and whose knee flexion range of motion was <90 degrees were excluded. A total of
194 knees were evaluated. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: A
semiquantitative ultrasonographic grading system was used to evaluate the
severity of femoral condylar cartilage erosion. The clinical symptoms and
functions were evaluated with the visual analog scale (VAS), Western Ontario and
McMaster Universities Osteoarthritis Index (WOMAC), and Lequesne index. The
association of the VAS/WOMAC/Lequesne index with the ultrasonographic grading was
assessed. RESULTS: Positive linear associations were found between the
ultrasonographic grading and the following: the VAS and the total scores and pain
subscales of both the Lequesne index and WOMAC. Multivariate logistic regression
analysis revealed grade-dependent association between VAS and ultrasonographic
grading after adjusting for age, sex, and body mass index. The WOMAC and Lequesne
index scores were associated with the ultrasonographic grading in more severe
degrees, particularly in the pain subscales. CONCLUSIONS: This semiquantitative
ultrasonographic grading system may well reflect the clinical symptoms and
functions related to knee OA as evaluated by the VAS, WOMAC, and Lequesne index.
This method provides a more comprehensive description and measurement of knee OA.
