Background

Robotics assisted surgery are tools that provide successful biomechanical reconstruction of the hip. We compare the accuracy of cup placement in the safe zones described by Lewinnek et al. and Callanan et al., leg length discrepancy (LLD) and global offset (GO) measurement in total hip arthroplasty (THA) using five diferent image guided techniques performed by six diferent surgeons.

Methods

Between June 2008 and April 2014, 2330 THRs were performed by six different surgeons. Ninety-three (4.69%) patients underwent robotic-assisted THA anterior approach, 135 (6.8%) had robotic-assisted THA posterior approach, 942 (47.5%) patients underwent fluoroscopic guided THA anterior approach, 708 (35.7%) had THA without guidance using posterior approach, 43 (2.1%) patients underwent navigation-guided anterior approach and 59 (2.9%) patients underwent radiographic-guided posterior approach THAs (Figure 1).
