EP160 Arthroscopic Remplissage Using an Iliotibial Band Allograft for Cam Over-Resection Improves Patient Outcomes at 2-year and 5-year Follow-Up
Bibliographic record
Abstract
Abstract Introduction Cam over-resection can lead to the loss of the hip suction seal, resulting in instability and hip pain. After failure of non-operative treatment, hip remplissage can be utilized to fill the femoral defect and restore the hip suction seal. There remains limited data in the literature regarding outcomes following hip remplissage. The purpose of the present study was to evaluate minimum 2- and 5-year patient-reported outcomes (PROs) after arthroscopic hip remplissage with an iliotibial band (ITB) allograft for cam over-resection. Methods Patients who underwent arthroscopic ITB hip remplissage from 2015 to 2022 by the senior author were included. PROs were obtained preoperatively,- and at short- (minimum 2 years) as well as at mid-term (minimum 5 years) postoperatively, including the 12-Item Short Form Survey (SF12) Physical Health Composite Score (PCS), SF12 Mental Health Composite Score (MCS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), modified Harris Hip Score (mHHS), and Hip Outcome Score (HOS) (Activities of Daily Living [ADL] and Sport). Results Forty-four patients (55% female, median age at surgery: 34 years [range: 14–58]) were included at short-term follow-up (median 2.3 years [range: 2.0-7.0 years]; 86% follow-up). Ten of these patients (80% female, median age at surgery: 42 years [range: 28–58]) were additionally followed up at mid-term (median 5.8 years [range: 5.0-7.2 years]). At short-term follow-up, SF-12 PCS, WOMAC total, mHHS, HOS-ADL, and HOS-Sport all statistically significantly improved post-operatively. Three patients went on to revision hip arthroscopy (7%), and another three patients converted to total hip arthroplasty (THA) (7%). In the mid-term follow-up analysis, there was a significant improvement in all patient reported outcomes, except for SF-12 MCS (p=0.055). Three patients went on to revision hip arthroscopy (7%), and another three patients converted to total hip arthroplasty (THA) (7%). Conclusion Arthroscopic hip remplissage using an ITB allograft improves patient reported outcomes at short-term follow-up. Subgroup analysis at mid-term follow-up demonstrated that clinical improvements are maintained, suggesting remplissage is a reasonable and successful salvage treatment option for hip pain and instability secondary to cam over-resection.

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.
