At what degree of anteversion was the acetabular cup placed during the right hip arthroplasty?

Placing the acetabular cup with about 15 degrees of anteversion is a common practice because it strikes a balance between stability and range of motion. Anteversion angles in this mid-range position help the cup open slightly toward the front, reducing the chance of posterior impingement and dislocation when the hip is flexed and rotated. If anteversion is too small, near zero, the risk of posterior dislocation and impingement increases; if it’s too large, the hip can become unstable anteriorly. So, 15 degrees sits in the typical safe range for maintaining joint stability, making it the best choice.
