Abstract

fetched live from OpenAlex

Femoro-acetabular impingement (FAI) is a common cause of hip pain and dysfunction in the young and active population. Despite reports of good short-term outcomes following treatment for FAI, less is known about the possible preoperative predictors of treatment outcome. The purpose of this study was to identify predictors of treatment outcome, using a patient-reported outcome measurement score (PROM) validated for use in a young and active population undergoing arthroscopic surgery for FAI. Patients were prospectively enrolled and analysed using the PROM International Hip Outcome Tool (iHOT-12) preoperatively and at a 2-year follow-up. Predictors of treatment outcome chosen for analysis were age, gender, duration of symptoms until surgery, level of cartilage damage, preoperative score and FAI type. A total of 198 patients, 122 males and 76 females (M: 61.6%, F: 38.4%), with a mean age of 41 ± 12.1 years, were analysed. The preoperative iHOT-12 score correlated with the postoperative iHOT-12 score at the 2-year follow-up. For one iHOT-12 point positive difference preoperatively, an additional 0.65 points were gained postoperatively at the 2-year follow-up (P ≤ 0.001). Age, gender, symptom duration until surgery, level of cartilage damage and FAI type did not have a statistically significant correlation to the postoperative score. Preoperative hip function as measured by the iHOT-12 is a potential predictor of outcome following FAI surgery relative to other factors.

Teacher imitation

Not 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.
