FP4.13 Patient-reported outcomes and satisfaction of first-generation FAI surgery: average 10-year follow-up of a prospective, multicenter cohort
Bibliographic record
Abstract
Abstract Background: Reports of mid to long-term outcomes of first-generation FAI surgery are limited. The purpose of this study was to characterize patient-reported outcome measures (PROMs) at an average 10 years after FAI surgery, and to identify predictors of clinical outcome. Methods: A prospective, multicenter cohort study was performed on patients treated for FAI with hip arthroscopy or surgical dislocation by seven surgeons. Inclusion criteria included primary surgery and diagnosis of isolated cam or combined cam/pincer type FAI. Patients were assessed with mHHS and HOOS pain and assessed relative to minimal clinically important difference (MCID) thresholds, and satisfaction. 462 hips were enrolled and 362 (80.1%) hips completed follow-up at 10.2±2.3 years postoperatively. Multivariate analysis was performed to identify independent predictors of outcome. Results: At a mean of 10.2±2.3 years follow-up, the mHHS increased from 61.6±15.2 to 83.1±19.3 (p < 0.0001) with 70.0% achieving MCID at final follow-up. Maximum alpha angle preoperatively <55 compared to >63 (BE: 0.06, CI: 0.01-0.12, p=0.002) and higher baseline mHHS (BE: 0.006, CI: 0.004-0.008, p<0.0001) predicted better follow-up mHHS. HOOS Pain scores improved from 57.1 ± 20.7 to 80.0 ± 22.5 (p<0.0001). BMI ≤ 30 (BE: 0.12, CI: 0.01-0.22, p=0.03) and higher (less pain) baseline HOOS-pain score (BE: 0.004, CI: 0.002-0.006, p<0.001) demonstrated higher postoperative HOOS-pain score. Surgical technique (hip arthroscopy vs surgical dislocation), lateral center edge angle, postoperative alpha angle, and labral repair were not predictive of outcome measures. Overall, 90.7% reported that they were satisfied with their surgical outcome. Conclusion: This study indicates that FAI surgery is an effective treatment option with maintained improvements in PROMs for most patients at a mean 10.2 years follow-up.

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.
