title: [Clinical results of minimally invasive total hip arthroplasty].
abstract: OBJECTIVE
  This article presents an analysis and review of recent literature with a focus on clinical results after minimally invasive (MIS) total hip arthroplasty (THA) and with special attention to the different approaches currently used.
  
  
  METHODS
  An online database (Medline) search for clinical trials after THA between 2007 and 2011 was performed with a special focus on prospective controlled randomized trials focusing on THA with a MIS approach. The data were analyzed for pain, blood loss, complications, gait analysis, Harris hip and other scores.
  
  
  RESULTS
  A total of 24 studies (19 comparative studies) were included in this study with a total of 801 MIS THA cases and 695 conventionally operated hips. Almost every study showed superior results for the MIS group with respect to postoperative pain, blood loss and rehabilitation but these advantages almost totally disappeared after 3-6 months. The complication rate was comparable in both groups. After 3-6 months the clinical scores, such as the Harris hip score did not show any differences between conventional and MIS groups.
  
  
  CONCLUSIONS
  In this present study all MIS approaches showed advantages over the conventional surgical approach but these benefits disappeared after 3-6 months. With comparable risks for complications, MIS surgical approaches are superior in the early postoperative phase and rehabilitation.
