Abstract
BACKGROUND: The meniscal flounce sign is a fold in the free, nonanchored inner edge of the medial meniscus that can be noted during routine arthroscopy of the knee. HYPOTHESIS: The meniscal flounce sign can be a significant indicator of the presence or absence of medial meniscus injury. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 4. METHODS: One hundred sixty-eight patients were prospectively evaluated at the time of the arthroscopy for the presence or absence of the arthroscopic meniscal flounce sign. These results were then correlated with the presence of medial meniscus tears. RESULTS: The presence of the meniscal flounce sign has a positive predictive value of a normal meniscus of 0.97 (63/65). The absence of the meniscal flounce sign has a positive predictive value of an abnormal meniscus of 0.98 (101/103). Specificity is 98%, and sensitivity is 97%. CONCLUSION: The absence of the arthroscopic meniscal flounce sign is a sensitive and specific predictor of the presence of medial meniscus tears that should alert the surgeon to probe carefully for an occult medial meniscus tear.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
