A prospective randomized study comparing accuracy and precision of acetabular component placement in total hip arthroplasty with use of novel electromagnetic navigation system versus freehand technique.
Patients with hip arthritis, who are to be treated with total hip arthroplasty will be randomized in two groups. Patents allocated to study group will get their acetabular components implanted with the help of electromagnetic navigation system. Patients allocated to the control group will get their acetabular components implanted with freehand technique. Accuracy and precision of implanted acetabular components will be assessed on images obtained by postoperative computed tomography. Postoperative inclination and anteversion angles of acetabular components will be measured by the independent technician. Results will be statistically analyzed and compared.
