Left stifle joint:
The supra- and infrapatellar recesses and the tendon sheath of the long digital extensor
muscle (communicates with the joint) of the left stifle joint contain a moderate amount
of anechoic effusion. The joint capsule reveals moderate thickening. Moderate
synovial proliferations are noted.
The cartilage layers as appreciated within the patellar sulcus at the femoral trochlea
and onto the femoral condyles are widely irregular in outline and increased in
echogenicity. The subchondral bone of the femoral condyles reveals multifocal
irregularity.
A moderate amount of osteophytes is noted at the femoral trochlea next to the sulcus of
the patella and at the periarticular margins of the femorotibial joint.
An echogenic stump of disrupted fibers is seen at the distal insertion of the cranial
cruciate ligament (CCL). Moderate periligamentous effusion is present.
The infrapatellar fat body is heterogenous and increased in echogenicity. The medial meniscus is in situ with mildly undulating surface and uniform
echogenicity. No injury is seen. The lateral meniscus is in situ with even surface and
uniform echogenicity. No meniscal disruption is seen. A moderate amount of
echogenic fibrous tissue is seen superficial/lateral to the lateral meniscal surface.
