Kan perineal post-fri traksjon i hofteartroskopi effektivt redusere perineale komplikasjoner?

30. oktober 2026 oppdatert av: ChunBao Li

Kan perineal postfri traksjon i hofteartroskopi effektivt redusere perineale komplikasjoner? Et multikenter prospektivt randomisert kontrollert forsøk

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

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Eksperimentell: Perineal Post-Fri Traksjon

Traction achieved with a thoraco-abdominal belt and contralateral groin strap; operating table tilted 10-15° Trendelenburg under fluoroscopy to 8-10 mm joint space. No perineal post is used, eliminating direct perineal pressure.

Aktiv komparator: 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.

Economic Evaluation - Pain Intensity
Tidsramme: 14 days after surgery

This study will conduct an economic evaluation from a healthcare sector and societal perspective. Pain intensity is assessed using the Visual Analog Scale (VAS), a unidimensional measure reported as scores on a 0-100 mm scale. Effectiveness analysis will incorporate this clinical outcome. Safety will be evaluated by monitoring the incidence of adverse events within 3 months postoperatively.

14 days after surgery
Economic Evaluation - Hip Function
Tidsramme: 14 days after surgery

This study will conduct an economic evaluation from a healthcare sector and societal perspective. Hip function is assessed using the modified Harris Hip Score (mHHS), a measure specifically for hip dysfunction and related symptoms, reported as scores on a 0-100 scale. Effectiveness analysis will incorporate this clinical outcome. Safety will be evaluated by monitoring the incidence of adverse events within 3 months postoperatively.

14 days after surgery
Mean Total Healthcare Cost per Patient within 14 Days Postoperatively
Tidsramme: Data collection period: From randomization until 14 days postoperatively.

This is the cost input measure for the economic evaluation, adopting a healthcare system perspective. All direct medical costs related to the surgery and subsequent care from the day of surgery until 14 days postoperatively will be collected via the Hospital Information System. Costs include fees for surgery, anesthesia, medical supplies, hospitalization, medication, imaging and laboratory tests, and additional costs for managing complications. The mean total cost per patient (in Chinese Yuan, CNY) will be calculated separately for the "conventional perineal-post traction group" and the "perineal-post-free traction group".

Data collection period: From randomization until 14 days postoperatively.
