    Total hip arthroplasty (THA) is effective for end-stage hip disease, emphasizing the importance of precise implant placement to prevent complications.

  • 2

    A portable CT-based navigation system was developed to improve accessibility and reduce costs compared to conventional CT navigation systems.

  • 3

    This study compared the accuracy and reproducibility of implant positioning between portable and conventional CT navigation systems in THA.

  • 4

    The study included 51 hips from each group, with patients matched for age, sex, and BMI to minimize confounding factors.

  • 5

    Postoperative evaluations confirmed the accuracy of implant orientation and position, highlighting the potential of portable navigation systems.
