Abstract
The purpose of this pilot study was to explore the relationship between pathologies in the acetabular labrum and end-stage osteoarthritis (OA). The study design was a prospective observational case series of 10 patients undergoing total hip replacement for end-stage OA. The arthroplasty procedure was performed using a standard lateral approach. An arthroscope was used along with a 5-mm probe to examine the labrum and the cartilage on the femoral and acetabular sides. Two blinded hip arthroscopy surgeons viewed the recordings and assessed the presence and location of labral tears and cartilage lesions according tothe Lage and Outerbridge classifications, respectively. The mean age of the 10 patients was 67 years. Labral pathology clustered in the anterior-superior quadrant was detected in all 10 hips. Tear patterns included longitudinal peripheral tears, fissuring, and large unstable tears. Significant inter-observer variability was noted. In all hips with focal acetabular articular lesions (40%), the lesion was located immediately adjacent to the labral pathology. In conclusion, all patients with end-stage OA were found to have a labral tear. The pathology, which was predominantly located in the anterior-superior part, was also a common site of more focal arthritic changes. This suggests that labral tears could be associated with the development of OA, indicating directions for further studies on this connection.

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.
