Most Elite Athletes Who Underwent Hip Arthroscopy for Femoroacetabular Impingement Syndrome Did Not Return to the Same Level of Sport, but the Majority Were Satisfied With the Outcome of Surgery
Bibliographic record
Abstract
Purpose To evaluate the 2‐year outcomes after arthroscopic surgical treatment for femoroacetabular impingement syndrome (FAIS) using validated patient‐reported outcome measurements in young elite athletes and to report the rate of return to sport. Methods Young elite athletes undergoing arthroscopic surgery for FAIS with 2 years of follow‐up were included. A young elite athlete was defined as an athlete aged 18 to 22 years at the time of surgery with a Hip Sports Activity Scale (HSAS) level greater than 6 before the onset of symptoms. The following patient‐reported outcome measurements were collected prospectively: Copenhagen Hip and Groin Outcome Score, 12‐item International Hip Outcome Tool, HSAS, visual analog scale (VAS), European Quality of Life (EQ) 5 Dimensions questionnaire, and EQ VAS. Furthermore, the patients answered a question related to satisfaction with surgery at follow‐up. Results A total of 84 athletes (67 male and 17 female athletes), with a mean age of 19.8 ± 1.5 years, completed the 2‐year follow‐up. Bilateral hip arthroscopy was performed in 57 athletes, generating a total of 141 included hips. The improvements in the Copenhagen Hip and Groin Outcome Score subscales, 12‐item International Hip Outcome Tool, EQ 5 Dimensions questionnaire, EQ VAS, and VAS for overall hip function were statistically significant ( P < .001). At the 2‐year follow‐up, 42% of the athletes reported an HSAS level of either 7 or 8 whereas 28% reported an HSAS level of 5 or 6. In total, 79% of the athletes were satisfied with the surgical procedure. Conclusions There are significant improvements in outcome measurements at the 2‐year follow‐up in elite young athletes undergoing arthroscopic hip surgery for FAIS. Although many of the athletes remained in high‐level sports 2 years after surgery, only 30% of the athletes returned to sport at the same level. Level of Evidence Level IV, 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.
