Can Stem Version Consistently Correct Native Femoral Version Using Robotic Guidance in Total Hip Arthroplasty?

The purpose of this study is to investigate whether robotic guidance in total hip arthroplasty (THA) can consistently correct native femoral version. One hundred seventy-five consecutive patients who underwent MAKO® (Stryker, Kalamazoo, Michigan) robotic-guidance THA were included in the study. The study population had a mean age of 57.9 years and a mean body mass index (BMI) of 30.41. Forty-eight percent of the population was male and 74% of the procedures were performed through an anterior approach. Robotic guidance in THA was effective in correcting native femoral version toward a target of 15°. This can be achieved using both the anterior and posterior approach; it is not affected by BMI.
