Ultrasound of the left stifle – Left stifle joint: 
Both the supra- and infrapatellar recess of the left stifle joint reveal moderate capsular
thickening and synovial proliferation. A moderate amount of anechoic effusion is
noted within the suprapatellar joint recess. The degree of infrapatellar effusion is only
mild. There is moderate periarticular soft tissue fibrosis noted mainly within the
suprapatellar region.
The cartilage layer onto the femoral trochlea is mildly uneven in thickness and outline.
Within the patellar sulcus a thin layer of cartilage is appreciated. The position oft he
patella is in situ.
A large amount of small osteophytes is seen at the femoral trochlea/patella sulcus. A
mild to moderate amount of osteophytes is present at the periarticular margins of the
femorotibial joint.
The cranial cruciate ligament (CCL) is difficult to recognize within the depth of the
femorotibial joint space because of the increased sound beam attenuation owing to the
periarticular fibrotic changes (these are likely secondary to the prior surgery). As far as
seen the CCL appears to be continuous but uneven in thickness and irregular in
echotexture, There is a mild amount of periligamentous effusion and regional
thickening of the synovial membrane.
The infrapatellar fat body presents moderate heterogeneity as found commonly in chronic degenerative joint disease (DJD). 
The medial meniscus 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.
