Ultrasonographic Evaluation of Canine stifle in case of CCLR

A 5 years old rottweiler  dog was presented to our clinic with touching toes lameness.With Orthopedic examination, CCLR was strongly suspected as it was positive cranial drawer test and Compression test of Henderson.

Stifle Ultrasonography was performed to confirm the diagnosis and CCLR rupture. In addition to that, ultrasonography could help identifying meniscal tears occur subsequently to CCLR.

Stifle radiographic examination reveals:

  1. Joint effusion
  2. Femoro-tibial displacement in the mediolateral stifle views (Tibial translation with the stifle and hock joint at 90 degree flexion)
