Brief 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

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: DOUBLE

Study Groups

Perineal Post-Free Traction

Group Type: EXPERIMENTAL

Perineal Post-Free Traction

Intervention Type: PROCEDURE

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.

Perineal Post Traction

Group Type: ACTIVE_COMPARATOR

Perineal Post Traction

Intervention Type: PROCEDURE

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.

Eligibility Criteria

Inclusion Criteria

• Aged 15 to 60 years;
• Met the diagnostic criteria of femoroacetabular impingement syndrome (FAI) and indicated for hip arthroscopy based on patient history, symptoms, signs, physical examination, imaging (pelvic anteroposterior view, frog-leg view, CT 3D reconstruction, MRI), and diagnostic injections;
• Able to read and sign the informed consent form.

Exclusion Criteria

• History of high-energy hip trauma, previous ipsilateral or contralateral hip surgery, avascular necrosis of the femoral head, slipped capital femoral epiphysis, Perthes disease, severe osteoporosis, tumors, acetabular stress fractures, or proliferative or immune hip diseases;

• Abnormal heart, lung, liver, kidney function, severe coagulation disorders, poorly controlled diabetes, judged by the researcher to have an infection risk;
• Consciousness disorders, psychiatric disorders, or neuromuscular dysfunction affecting lower limb function;
• Active infection foci (systemic or local infectious lesions);
• Pregnancy, lactation, or planned pregnancy during the clinical study period;
• Participation in another clinical trial within the past 3 months;
• Patients deemed unsuitable for the clinical trial by the researcher for other reasons.

• Minimum Eligible Age: 15 Years
• Maximum Eligible Age: 60 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: No
