Femoral Neck Impingement Cysts Treated With Biocomposite Implants in the Setting of Femoroacetabular Impingement Show Improvement in Patient‐Reported Outcomes at a Minimum 2‐Year Follow‐Up
Bibliographic record
Abstract
Purpose To assess minimum 2‐year outcomes in patients treated with biocomposite anchors for impingement cysts of the femoral neck during hip arthroscopy for femoroacetabular impingement. Methods Patients aged 18 to 65 years who underwent treatment of a femoral neck impingement cyst with placement of a suture anchor by the senior surgeon between January 1, 2007, and December 1, 2019, and were eligible for a minimum 2‐year follow‐up were identified. Demographic, surgical, and patient‐reported outcomes—including Hip Outcome Score–Activities of Daily Living (HOS‐ADL), Hip Outcome Score–Sport (HOS‐SSS), modified Harris Hip Score (mHHS), patient satisfaction, and Tegner Activity Scale—were retrospectively reviewed from the senior surgeon’s prospectively collected database. Complications, including femoral neck fracture, need for revision, or conversion to total hip arthroplasty, were assessed from patient charts and postoperative follow‐up surveys. Postoperative magnetic resonance images were assessed for suture anchor integration and presence of a residual cyst. Results Fifty patients (50 hips) met inclusion criteria, with a median age at surgery of 45 (range, 19‐63) years. Minimum 2‐year follow‐up was obtained for 43 of 50 (86%) patients, with a mean follow‐up time of 3.4 ± 1.4 years. One patient reported conversion to total hip arthroplasty, and no additional patients reported revision surgery or postoperative femoral neck fractures. HOS‐ADL, HOS‐SSS, mHHS, Western Ontario and McMaster Universities Osteoarthritis Index, and Short Form 12 Physical Component Summary scores significantly improved after hip arthroscopy ( P < .001), with most patients attaining minimum clinically significant difference and patient acceptable symptom state for HOS‐ADL, HOS‐SSS, and mHHS. Notably, the median postoperative patient satisfaction score was 9.0 of 10 (range, 1‐10). Conclusions Hips with femoral neck impingement cysts treated with biocomposite suture anchors showed excellent patient‐reported outcomes and high survivorship at a minimum 2‐year follow‐up, with most patients achieving mHHS minimum clinically significant difference and patient acceptable symptom state. Level of Evidence Level IV, retrospective therapeutic case series.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
