The Effect of an Acetabular Labral Tear Repair Resection and Reconstruction on the Hip Fluid Seal

摘要

Objectives:The acetabular labrum is theorized to have an important role in the normal function of the hip through the hip fluid seal. The hip fluid seal functions to create intra-articular fluid pressurization and stability to distractive forces. Yet, the effect of a labral tear or partial labral resection, and interventions including labral repair and labral reconstruction, on the hip fluid seal remain to be defined. The purpose of the current study was to characterize the hip fluid seal, including intra-articular fluid pressurization and stability to distraction, in six different labral conditions: (1) intact, (2) labral tear, (3) labral repair, (4) partial resection, (5) labral reconstruction with iliotibial band, and (6) complete resection. Additionally, the current study investigates the effect of looped (3a) and through (3b) type labral suture repairs on the hip fluid seal.
