The usefulness of minimal invasive hip replacement is frequently discussed but there is a lack of data on the effect of the surgical approach on early results. We wanted to study the effect of the surgical approach on the peri- and early postoperative outcome. In a prospective case control study 315 elective hip replacements were performed between January 2008 and March 2010. Until March 2009 a lateral transgluteal approach (STD) was used, then the approach was changed to a minimal invasive anterior approach (MIS). All operations were performed in the same routine setting not affected by the approach. Duration of operation, complications and bloodloss were assessed. 1 week postoperatively, independent mobility, stairs, central analgetics were analysed and length of stay was recorded. At 6 and 12 weeks, pain and patients satisfaction (VAS) and the Harris Hip Score were assessed. Pre- and postoperative radiographs were compared for component position and orientation (EBRA).Introduction
