Abstract Background A computerized robotic surgical system was developed from 1986 by the Thomas J. Watson Research Center. In 1992 the system unit Orthodoc ® and the milling robot Robodoc ® were first used on humans. We present the results achieved with Robodoc‐assisted total hip arthroplasty in 97 hips. Methods Between 1997 and 2002, 143 total hip replacements (128 patients) were performed using the Robodoc system. This is a consecutive series. Complete follow‐up was possible in 97 hips at a mean follow‐up period of 3.8 years. Results Technical complications directly related to the robotic device occurred in nine cases (9.3%). The pre‐operative Merle d'Aubigne score was determined at 8.1 points compared to a post‐operative mean score of 16.2. There was no sign of femoral stem loosening on radiographs. Conclusions Robotic‐assisted total hip arthroplasty with the Orthodoc/ Robodoc system achieves equal results as compared to a manual technique. However, there was a high number of technical complications directly or indirectly related to the robot. Copyright © 2007 John Wiley & Sons, Ltd.
