Return to Duty After Mini‐Open Arthroscopic‐Assisted Treatment of Femoroacetabular Impingement in an Active Military Population
Bibliographic record
Abstract
Purpose To report the return‐to‐duty rate and surgical outcomes in a military population after mini‐open arthroscopic‐assisted surgery for femoroacetabular impingement (FAI) in an effort to affirm its efficacy. Methods A retrospective review of consecutive active‐duty patients receiving mini‐open arthroscopic‐assisted surgery for FAI between 2007 and 2011 was performed. Patients younger than 18 years, non–active‐duty patients, and patients with prior hip surgery were excluded. Demographic, radiographic, and duty‐status data were collected. The primary outcome measure was a return to duty. Outcome scores were obtained in a proportion of the cohort, including the modified Harris Hip Score, Single Assessment Numeric Evaluation score, Western Ontario and McMaster Universities Osteoarthritis Index score, patient satisfaction score, and Veterans RAND 12 (VR‐12) score. All patients had achieved a minimum of 1 year of follow‐up at the time of assessment. All P values for significance were set at .05 or lower. Results Of 182 patients (average age, 30.4 years), 156 (86%) were available for follow‐up with return‐to‐duty data at an average of 2.8 years (range, 1‐6 years). Of the patients, 78% returned to full duty (53%) or returned to duty with restrictions (25%). Outcome scores were available for 101 of 182 patients (55%) with duty rates similar to the total cohort (81% who returned to duty: 58% with no restrictions and 23% with restrictions). Return to duty correlated with improved outcomes compared with those who were medically discharged with respect to the modified Harris Hip Score (68.2 vs 54.5, P < .03), Single Assessment Numeric Evaluation score (48.2 vs 25.3, P < .02), and VR‐12 physical (39.7 vs 33.2, P < .05) and VR‐12 mental (54.5 vs 43.4, P < .005) scores. Conclusions Mini‐open arthroscopic‐assisted surgery for FAI is successful in returning most service members to duty at short‐term follow‐up. Return correlates with improved outcome scores, although previously reported minimally clinical important difference and patient acceptable symptomatic state threshold values were not uniformly achieved. Level of Evidence Level IV, retrospective case series.

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.
