Osteochondritis Dissecans in Pediatric Patients with Juvenile Idiopathic Arthritis
Bibliographic record
Abstract
To the Editor: Joint pain and swelling are common symptoms of patients with juvenile idiopathic arthritis (JIA) with active joint inflammation. When patients with JIA have persistent pain or mechanical symptoms despite treatment of their inflammation, other causes must be considered. Osteochondritis dissecans (OCD) is a focal alteration of subchondral bone formation that causes softening of the overlying cartilage, which can progress to instability, eventual osteochondral detachment, and early osteoarthritis1. Poorly localized knee pain with activity is common in early OCD lesions, and progresses to swelling, catching, or locking as the lesion becomes unstable1. The incidence in the general population is 9.5–29/100,000, occurring 2–3.8 times more frequently in males than females1,2,3. The most commonly affected joint is the knee1. Fifty-one to 69% of knee lesions affect the medial femoral condyle (MFC), and 16.5–33% affect the lateral femoral condyle (LFC)1,2,3. First-line management is conservative, with 33.5% requiring surgical intervention4. Multiple theories regarding the etiology of OCD lesions … Address correspondence to Dr. R.A.

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.
