Bilateral Osteochondritis Dissecans of the Femoral Condyles in Both Knees: A Report of Two Sibling Cases
Bibliographic record
Abstract
Case Reports1. Case 1 A 32-year-old female visited our hospital with a complaint of right knee pain.She had come three months ago for similar symptoms and had been diagnosed with OCD of the right knee based on clinical presentation and imaging studies obtained at that time.At the latest presentation, the pain increased in severity and the patient required a cane for ambulation due to a catching sensation in her right knee.Physical examination revealed moderate swelling and stiffness of the right knee.Localized tenderness was noted on the lateral and medial joint lines and twenty degrees of passive extension was lost.Standing weight-bearing posterior-anterior radiographs were obtained and revealed irregularities of bilateral femoral condyles in both knees on the weight-bearing portion of the femur (Fig. 1).Magnetic resonance imaging (MRI) showed a fragment in the center of the both femoral condyles with bone marrow edema.A fissure between the articular fragment and femoral bone base was also seen.Additionally, a 2.8 cm by 2.5 cm displaced articular loose body shadow was noticed on the lateral femoral condyle. 1) Operative techniqueThe patient was brought to the operating room and prepped and draped in the standard sterile fashion.Arthroscopic examination was performed first and findings revealed a 2.8 cm

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.
