Ultrasound of the left and right stifle joints – Left:
Mild to moderate anechoic effusion is noted within the suprapatellar and infrapatellar recess of the left stifle joint. The synovium & joint capsule reveal marked thickening.
A moderate amount of osteophytes is seen at the periarticular margins of the femoropatellar and a mild amount at the margins of the femorotibial joint. Mild subchondral bone irregularity is noted.
The cranial cruciate ligament presents as a short & smoothly delineated echogenic stump at the intercondylar eminence of the tibia. Scant periligamentous effusion is seen.
The caudal horn of the medial meniscus is not directly seen. The visible portion of the medial meniscus is in situ, but reveals non-uniform echogenicity and uneven outline with a possible hypoechoic interruption. The lateral meniscus is in situ and within normal limits except for a mild overall increase in echogenicity.
Right:
Moderate anechoic effusion is noted within the suprapatellar recess and infrapatellar recess of the right stifle joint. The synovial membranes are moderately thickened.
A moderate amount of osteophytes is seen at the periarticular margins of the femoropatellar and a mild amount at the margins of the femorotibial joint.
A small portion of the cranial cruciate ligament is continuous but reveals uneven surface and width with irregular echogenicity. Echogenic tissue is seen next to the tibial eminence. There is a mild amount of periligamentous effusion.
The caudal horn of the medial meniscus is not directly seen. The visible portion of the medial meniscus is in situ, uniform in echogenicity and smooth in outline. The lateral meniscus is in situ, uniform in echogenicity and smooth in outline.
