Discoid meniscus in children: treatment and outcome.
Bibliographic record
Abstract
INTRODUCTION: Discoid meniscus is an atavistic anomaly in which the meniscus of the knee, predominantly the lateral meniscus, is discoid rather than semilunar in shape. The abnormality is diagnosed relatively infrequently and may even go unrecognized or be untreated. Treatment has consisted of either partial or complete meniscectomy performed either arthroscopically or by open arthrotomy. Our purpose was to examine the outcome of treatment for discoid meniscus in children. METHODS: Since 1974, 34 children, including 2 with bilateral involvement, have been treated for discoid meniscus at the Children's Hospital of Eastern Ontario, a major pediatric referral centre. The average age of the children at the time of surgery was 11 years 4 months (range from 6 yr 2 mo-18 yr 6 mo). The average follow-up was 3 years (range from 1 mo-22 yr). The lateral meniscus was affected in 35 of the 36 knees. Treatment consisted of partial resection in 19 cases, complete resection in 13; 4 did not undergo resection. RESULTS: There were 16 excellent, 10 good, 6 fair and 4 poor results at the time of most recent follow-up. In 2 cases degenerative changes were evident radiologically. CONCLUSION: Partial resection of discoid menisci is preferable in children, but in complete dislocation of the entire menisci, total removal is necessary.

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.
