Abstract

Objective: Investigate the efficiency/accuracy of surgical automation versus manual component implantation in DA THA.

Methods: Retrospective review of 111 hips: 51 hips via automation and 60 hips via manual technique for DA THA.

Results: OR time averaged 8 min faster in the Automated group, compared to Manual group (p = 0.0009). Average femoral size was one size larger in the Automated group compared to Manual group (p = 0.007). No clinically significant differences were found between Manual and Automated groups for cup position or limb-length discrepancy. One calcar fracture occurred in the Automated group.

Conclusion: Surgical automation is efficient and accurate for DA THA.
