Ultrasound Evaluation of Normal and Abnormal Posterior Cruciate Ligament - a Prospective Study

the sensitivity and specificity of Ultrasound in diagnosing Posterior cruciate ligament (PCL) pathology. MATERIALS AND METH ODS: This prospective study was conducted over a period of 8 months and included 110 patients. An ultrasound of the knee was performed before the Magnetic Resonance Imaging (MRI) and a diagnosis regarding PCL appearance was made on the ultrasound. After the ultrasound an MRI using standard protocol was performed and the ultrasound and MRI findings were compared. RESULTS: Sensitivity of ultrasound in recognizing PCL pathology was 90.90%. Specificity was 100%.Positive predictive value was 100%.Negative predictive value was 99%. Significant correlation was found between the ultrasound and MRI appearance of PCL pathology. CONCLUSION: Ultrasound is sensitive in the detection of PCL injury, with an excellent positive predictive value and high sensitivity.
