Ultrasound of the left stifle joint – Left stifle joint:
Both the supra- and infrapatellar recess of the left stifle joint reveal moderate anechoic effusion, capsular thickening and synovial proliferation.
The cartilage layers as appreciated onto the femoral trochlea and the femoral condyles are largely even and anechoic. Only at the periarticular margins cartilage layers present mildly uneven and roughened surface.
A large amount of small osteophytes is seen at the femoral trochlea/patella sulcus and at the periarticular margins of the femorotibial joint.
The cranial cruciate ligament (CCL) presents as an echogenic stump at the intercondylar eminence of the tibia with mild periligamentous effusion and mild regional thickening of the synovial membrane.
The infrapatellar fat body presents mild heterogeneity as found commonly in chronic degenerative joint disease (DJD).
The cranial and mid portion of the medial meniscus are well visible. It is in situ with uniform echogenicity, but undulating surface and an incomplete cleft between the medial collateral ligament and the medial meniscal surface is seen. The caudal horn is not seen.
The lateral meniscus is in situ with even surface, yet it reveals largely uniform increase in echogenicity. A mild amount of echogenic tissue proliferation is noted superficial to the lateral meniscus
