Objectives
Narrative objectives1
The aim of this study is to evaluate in-vivo kinematics of total hip arthroplasty during daily activities using the accelerometer-based navigation device (HipAlign system, Zimmer Biomet, Warsaw, IN, USA) in comparison with that using conventional alignment guide.

Assessment
Primary outcomes
To evaluate with the validated image matching technique whether the accelerometer-based navigation device (HipAlign system, Zimmer Biomet, Warsaw, IN, USA) provides significantly larger distances between the acetabular liner and the stem neck (liner-to-neck clearance) during daily activities compared to conventional alignment guide.
Key secondary outcomes
To evaluate with CT images whether the accelerometer-based navigation device (HipAlign system, Zimmer Biomet, Warsaw, IN, USA) provides significantly higher precisions in the acetabular cup alignment compared to conventional alignment guide.
