Prospective Randomized Study of 2 Different Techniques for Endoscopic Iliopsoas Tendon Release in the Treatment of Internal Snapping Hip Syndrome
Bibliographic record
Abstract
PURPOSE: To evaluate the short-term results of 2 different techniques of endoscopic iliopsoas tendon release for the treatment of internal snapping hip syndrome. METHODS: Between January 2005 and January 2007, a consecutive series of patients with the diagnosis of internal snapping hip syndrome was treated with endoscopic release of the iliopsoas tendon. The patients were randomized into 2 different groups. Patients in group 1 were treated with endoscopic iliopsoas tendon release at the lesser trochanter, and patients in group 2 were treated with endoscopic transcapsular psoas release from the peripheral compartment. Hip arthroscopy of both the central and peripheral compartments was performed in both groups using the lateral approach. Associated injuries were identified and treated arthroscopically. Postoperative physical therapy was the same for both series, and each patient received 400 mg of celecoxib daily for 21 days after surgery. Preoperative and postoperative Western Ontario MacMaster (WOMAC) scores and imaging studies were evaluated. RESULTS: Nineteen patients were included in the study: 10 in group 1 (5 male and 5 female; average age, 29.5 years) and 9 in group 2 (8 female and 1 male; average age, 32.6 years). No statistical difference was found in group composition. Associated injuries were found and treated in 8 patients in group 1 and 7 patients in group 2. No statistical difference was found between groups in preoperative WOMAC scores, and every patient in both groups had an improvement in the WOMAC score. Improvements in WOMAC scores were statistically significant in both groups, and no difference was found in postoperative WOMAC results between groups. No complications were seen. CONCLUSIONS: Iliopsoas tendon release at the level of the lesser trochanter or at the level of the hip joint using a transcapsular technique is effective and reproducible. We found no clinical difference in the results of both techniques.

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.
