Ultrasound of the left stifle joint – Both the supra- and infrapatellar recess of the left stifle joint reveal marked capsular
thickening and synovial proliferation.
The cartilage layers as appreciated onto the femoral trochlea and the femoral condyles
are largely even and anechoic. At the femoral trochea the thickness and surface of the
cartilage layer are mildly uneven.
A large amount of small osteophytes is seen at the femoral trochlea/patella sulcus. A
moderate amount of osteophytes is present 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 periligamentous effusion and marked regional
thickening of the synovial membrane.
The infrapatellar fat body presents mild heterogeneity with emerging mineralizations
as found commonly in chronic degenerative joint disease (DJD). 
The medial meniscus is well visible. It is in situ with even surface and uniform echogenicity.
The lateral meniscus reveals marked non-uniform increase in echogenicity. A mild
amount of echogenic tissue proliferation is noted superficial to the lateral meniscus
