股関節唇の内側から外側への損傷に対する関節鏡視下反転修復術

The acetabular labrum is a fibrocartilaginous structure that deepens the acetabular socket and helps maintain a suction seal. In patients with hip dysplasia, a distinct labral tear pattern called an inside-out labral tear is often seen. This tear pattern is particularly challenging to correct via conventional techniques since the labrum can potentially remain everted and insufficiently restore the native hip labral suction seal after repair. An inverted hip labral repair technique is performed for this pathology at our institution and focuses on achieving optimal labral orientation to enhance the suction seal and joint stability, particularly in dysplastic hips. This Technical Note aims to describe the key surgical principles and clinical considerations of inverted hip labral repair.
