Rare dual stifle tendon avulsion reported in a juvenile dog

A case report in Veterinary Radiology & Ultrasound describes what the authors say is the first documented canine case of concurrent partial avulsion of both the popliteal and long digital extensor tendons, confirmed with MRI and ultrasonography. The patient was a 5-month-old Chesapeake Bay Retriever with persistent left pelvic limb lameness 11 days after an abnormal landing. Imaging also identified bone marrow edema, mild synovial effusion, and a low-grade lateral collateral ligament sprain, and the dog improved with medical, rather than surgical, management.

Why it matters: For veterinary teams, the report is a reminder that uncommon stifle soft-tissue injuries can be missed if workups stop at radiographs. Prior veterinary literature has described isolated or differently patterned long digital extensor or popliteal injuries, including older reports tied to patellar luxation and other single-tendon lesions, but this combination appears to be newly documented. That makes advanced imaging especially relevant when a young dog has ongoing weight-bearing lameness after trauma and routine findings don't fully explain the clinical picture. (eurekamag.com)

What to watch: Whether this report leads clinicians to more routinely consider MRI or targeted ultrasound for persistent post-traumatic juvenile stifle lameness, and whether additional cases clarify when conservative care is enough versus when surgery is needed. (eurekamag.com)
