Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients with radiological and symptomatic femoroacetabular impingement who have not undergone previous hip surgery.

Probably not a fit

Patients with prior hip surgeries, malignant diseases, or significant hip joint conditions may not benefit from this study.

What this trial studies

This study investigates the effects of capsular closure versus non-capsular closure during hip arthroscopy in patients diagnosed with femoroacetabular impingement (FAI). It aims to determine if capsular closure leads to better patient-reported outcomes compared to leaving the capsule open after surgery. Patients will undergo a minimum of three months of physiotherapy before being considered for surgery. The outcomes will be measured using validated patient-reported outcome measures to assess the effectiveness of the surgical techniques.

Why it matters

Potential benefit: If successful, this study could improve surgical outcomes and recovery for patients with femoroacetabular impingement.

How similar studies have gone: While similar studies on surgical techniques exist, this specific comparison of capsular closure methods in FAI is relatively novel.
