Video Transcription

Video Summary

In this video transcript, the speaker discusses a study published in the Journal of Arthroscopy on patients with acetabular dysplasia and hip instability. They explain that chronic shear stress between the femoral head and the acetabular roof leads to compensational labral hypertrophy. The speaker introduces a new parameter, the combined lateral center edge angle, to compare the labral coverage between different degrees of acetabular boning coverage. The study conducted a retrospective observational cohort study with 341 patients and 386 hips. Results demonstrated that despite varying degrees of acetabular boning coverage, the labral size compensates, resulting in similar lateral osseolabral coverage in patients with acetabular dysplasia when compared to normal hips.
