The “Bird's Eye” and “Upper Deck” Views in Hip Arthroscopy: Powerful Arthroscopic Perspectives for Acetabuloplasty

Abstract

Arthroscopic acetabuloplasty involves trimming of bone from the acetabular rim. Although early techniques often involved detachment of the labrum prior to bone resection, recent studies have reported on acetabuloplasty without labral detachment. This method has the benefit of preserving the labro-osseous junction, but visualization of the acetabular rim may be more difficult. Compromised visualization can lead to incomplete resection and residual impingement. We describe an arthroscopic perspective called the “bird's eye” and “upper deck” views that facilitates optimal visualization of the acetabuloplasty without labral detachment.
