This is Dr. David

Dr. David :

yes, an ultrasound can look into your knee. and can check for fluid.

Dr. David :

but the resolution of an ultrasound is not as fine as an MRI scan.

Dr. David :

and small tears in the meniscus can be missed on ultrasound.

Dr. David :

but it is a good first scan choice for the knee.

Dr. David :

here is a good study comparing ultrasounds vs MRI scans for meniscal tears

Dr. David :

Ultrasound was found to be correct in 25 (86.2%) of the 29 meniscal tears and incorrect in four menisci. As a result, ultrasound yielded 86.2% sensitivity for meniscal tears, 84.9% specificity, 85.4% accuracy, 75.8% positive predictive value, and 91.8% negative predictive value.
