The impact of surgeons’ visual angle misperception on acetabular cup positioning accuracy: a retrospective multicenter cohort study
Our study is the first to provide that visual angle misperception is a hidden cause of cup positioning bias in THA, and experience alone cannot eliminate this bias causing by visual angle misperception, although experience reduced variability in placement. Recognizing and addressing this cognitive bias, and further targeted training to improve spatial perception, compensate inherent angle misperception bias, may lead to better patient outcomes.
