Outcome Measures

Primary Outcomes (1)

  • Acetabular component position

    Comparison of the precision and the accuracy of acetabular components between both groups

    Up to 48 hours after surgery

Secondary Outcomes (2)

  • Surgical time

    Immediately after surgical procedure

  • Clinical result

    8-10 weeks postoperatively

Study Arms (2)

Electromagnetic navigation

EXPERIMENTAL

In the study group acetabular components in total hip arthroplasty will be placed with the help of electromagnetic image-less navigation system. Reference plane will be anterior pelvic plane.

Procedure: Electromagnetic navigation

Freehand

ACTIVE COMPARATOR

In the control group acetabular components in total hip arthroplasty will be placed with the help of the freehand technique.

Procedure: Freehand

Interventions

Acetabular component placement in total hip arthroplasty will be performed wit the help of electromagnetic image-less navigation system.
