Case Study

ORTHO – Partial cranial cruciate ligament (CCL) rupture with degenerative joint disease in a 4 year old MN Chesapeake Bay Retriever

This 4 year old MN Chesapeake Bay Retriever presented for lameness right hind; positive cranial drawer and CTT, suspect partial CCL tear.

DX

The ultrasonographic examination of the right stifle joint is compatible with moderate chronic generalized degenerative joint disease with synovialitis and mild osteoarthritis. Moreover the findings support the presence of partial rupture of the CCL

Image Interpretation

Ultrasound of the right stifle –

The suprapatellar recess presents marked thickening of the synovial lining with mild anechoic effusion. Only scant effusion and midl synovial thickening are noted within the infrapatellar recess of the stifle joint. Mild periarticular osteophytes are noted. The infrapatellar fat pad presents mild heterogeneity with a solitary anechoic cyst.m The cranial cruciate ligament (CCL) is continuous but uneven inoutline and diameter with an irregular echo pattern and echogenicity.
