Primary outcomePrimary: Acetabular Cup Antiversion — 19.8; 11.5 degree
Summary
The purpose of this study is to identify radiological factors on TC of the hip that could lead to prediction of development of symptomatic psoas impingement in patients with protruding acetabular cup after primary total hip arthroplasty.

Eligibility Criteria
Inclusion Criteria
