The mean age of the patients was 33 years (SD: 9.78,
range: 19-51 ) and sexual distribution was equal( 24 men and 24 women).
Cartilage thickness was in highest level in Notch and in 90º flextion position.
Sensivity and specificity of ultrasound in determining abnormal cartilage transparency in comparison with arthroscopy as a gold standard test is 100% (10 cases were abnormal in both ultrasound and arthroscopy and 38 persons were normal in both techniques).
Sensitivity of ultrasound in grading was 100% meanwhile its specificty was 88.2% (30 persons had normal grade while it was 34 in arthroscopy). We had only 4 patients with erosion in ultrasound which was reported normal in arthroscopy,
other grades were similar in both techniques (30 patients had normal grade,
9 patients had complete defect with normal bone and 5 patients had complete defect with bone involvment).(table1)
Thereafter sensitivity and specificity of ultrasound in patients with abnormal grade determined base on two devided osteophyte/calcification group and non osteophyte/calcification group.
Sensitivity and specificity was 100% in presence of osteophyte or calcification however it was 100% and 88.2% respectively,
in group without osteophyte or calcification.
