Trochlear cartilage of the knee joint is known as a lubricant and force reducing factor to the underlying bone.
MRI is known as choice imaging modality to assess cartilages of knee,
but many physicians use ultrasound as an adjunct in the diagnosis of some lesions alongside of MRI.
Ultrasound could be choice for screening because of its low cost and high accuracy in detecting cartilage lesions.
In this study,
we have evaluated lesions of trochlear cartilage by...

This study was performed on 48 patients scheduled for arthroscopic evaluation in an referral academic orthopedic center mostly with traumatic lesions .
One day before the surgery,
patients are referred to the department of radiology and after taking inform consent ultrasound assessment was done by an expert radiologist,
free of charge.
Ultrasound was performed by a high resulotion ultrasound unit (Esaote My Lab 70) with 13 MHZ linear probe and in supine position in full extension and...

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...
Conclusion

Ultrasound has a high sensivity and specificity in detecting trochlear cartilage lesions of knee and can be very helpful in patients with MRI contraindication.
