Summary

The goal of this clinical trial is to analyze the impact of perineal post-free traction versus traditional perineal post traction on perineal complications in hip arthroscopy. The main question it aims to answer is: • Can Perineal Post-Free Traction in Hip Arthroscopy Effectively Reduce Perineal Complications? Researchers will compare the perineal-post-free traction group with the conventional perineal-post traction group to see if the former decreases perineal complications and improves efficiency without compromising surgical outcomes. Participants will: * Undergo either perineal-post-free or standard perineal-post traction during hip arthroscopy * Complete nerve-injury checks on day 1 and at discharge, and hip-function questionnaires (VAS, mHHS, IHOT-12, HOS) at 3 months * Allow collection of operating times, hospital stay, and direct medical costs for economic analysis

Conditions

• Femoroacetabular Impingement Syndrome

Interventions

Type	Name	Description
PROCEDURE	Perineal Post-Free Traction	Traction achieved with a thoraco-abdominal belt and contralateral groin strap; operating table tilted 10-15° Trendelenburg; gradual 10-20 kg distraction under fluoroscopy to 8-10 mm joint space. No perineal post is used, eliminating direct perineal pressure.
PROCEDURE	Perineal Post Traction	Standard traction table with padded perineal post placed against the groin providing counter-traction; affected limb distracted under fluoroscopy to 8-10 mm joint space while contralateral limb is abducted.
