Abstract
CASE: We report a 67-year-old gentleman who presented with a painful unstable knee. He had undergone a successful total knee arthroplasty 12 years earlier and was highly functional. He presented with a 10-month history of mild pain, instability, and gait alteration. During revision surgery, there was a loss of bony support, and a fractured femoral component was identified. He required constrained revision components for reconstruction and made an uneventful recovery. CONCLUSIONS: Fractured femoral components are rare complications of modern primary total knee arthroplasty. Loss of bony support in critical areas of high loading will inevitably lead to catastrophic component failure.

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 it
