Aim To explore the relationship among clinical, radiological and ultrasonographical findings in knee osteoarthritis ( OA ). Method Sixty‐one patients (122 knees) with knee OA were enrolled. Patients' knees were classified into two groups according to symptom severity. Group I consisted of 61 more symptomatic knees and Group II comprised 61 less symptomatic knees. Subjects were clinically assessed for pain and functional status by using a visual analog scale and the Western Ontario and McMaster Universities Arthritis Index ( WOMAC ), respectively. Knee radiographs were evaluated by using the Kellgren–Lawrence (K–L) grading system. All knees were also evaluated ultrasonographically for meniscal bulging, distal femoral cartilage thickness, cartilage grading and also for the presence of effusion, Baker's cyst and so on. Results Baker's cyst and joint effusion were observed more in Group I when compared with Group II . Positive correlations were found between meniscal bulging and all WOMAC scores (all P < 0.05). K–L grades of the patients were also positively correlated with WOMAC scores (all P < 0.05). Meniscal bulging measurements and K–L grades were positively correlated ( P < 0.001). There was a negative correlation between cartilage grades and cartilage thickness measurements (all P < 0.001). Conclusions We found that joint space narrowing seemed to be associated with meniscal bulging. Moreover, increased meniscal bulging and presence of B aker's cyst/joint effusion were associated with worse pain or poorer function.
