Magnetic resonance imaging and arthroscopy of a discoid lateral meniscus in a dog
Bibliographic record
Abstract
Summary For the first time in veterinary literature, magnetic resonance and arthroscopic features of a discoid lateral meniscus in a dog are described. A 15-monthold Labrador Retriever with a history of mild intermittent left hindlimb lameness was referred to our clinic. Physical examination revealed mild joint effusion of the left stifle and absence of a cranial drawer motion and tibial compression test. Survey radiographs demonstrated mild joint effusion and peri-articular new bone formation. Low-field magnetic resonance tomography of the left stifle joint demonstrated injury of the cranial cruciate ligament and a discoid lateral meniscus. Two weeks later, arthroscopy revealed a partial tear of the cranial cruciate ligament with mild synovitis. Furthermore, some fibres inserted abnormally cranial to the inter-meniscal and cranial tibial ligament of the medial meniscus. The lateral meniscus was discoid in shape. Subsequent arthrotomy confirmed the diagnoses. Discoid meniscus is a rare finding in the dog with unknown clinical relevance whereas it is well known in humans. A 15-month-old Labrador Retriever with mild left hindlimb lameness, mild joint effusion of the left stifle but without signs of stifle instability is presented in this report. Low-field magnetic resonance tomography demonstrated injury of the cranial cruciate ligament and a discoid lateral meniscus. Subsequent arthroscopy and arthrotomy confirmed these findings. A literature review on discoid meniscus in humans and in dogs is presented.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
