The role of high resolution ultrasound in the assessment of knee osteoarthritis

Abstract

ur Study was carried out upon 20 patients with knee OA (12 females and 8 males), with a mean age of 52.85 ± 11.2 years (ranged between 35 – 75 years). These patients were selected from those who were referred to radiology department from rheumatology or orthopedics outpatient clinics. Each subject was evaluated for the presence of medial and lateral femoral cartilage thinning, medial and lateral femoral and tibial osteophytes, medial and lateral meniscal degeneration, joint effusion and Baker's cyst using ultrasound and MRI. The sensitivity, specificity, accuracy, PPV, NPV and the P value for each parameter were calculated. In our study, ultrasound showed excellent sensitivity in the detection of medial cartilage thinning (90%), medial osteophytes (90%), medial and lateral meniscal degeneration (9404% and 93.3%), joint effusion (90%) and Baker's
