Abstract

fetched live from OpenAlex

Introduction: This case report describes a 13-year-old male patient, with unusual magnetic resonance imaging findings of subchondral cysts associated with an osteochondral defect of the right knee. Case Report: The patient presented with a six-week history of right knee pain, swelling and locking. Clinical examination revealed a loose body in the suprapatellar pouch, a small effusion, and a fixed flexion deformity. Imaging features revealed an unusual fountain-like morphology of the subchondral cysts, deep to the defect. The patient underwent surgical repair. Conclusion: This radiographical finding may suggest an interplay between biomechanical stress and subchondral bone remodeling, warranting further investigation into the pathogenesis of such morphology.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
