Minimally invasive versus conventional exposure for total hip arthroplasty: a systematic review and meta-analysis of clinical and radiological outcomes
Int Orthop. 2011 Feb;35(2):173-84Data from 16 non RCTs and 12 RCTs (2849 hips) of variable quality were analyzed to determine whether minimally invasive surgery (MIS) is superior to a conventional exposure for total hip arthroplasty (THA), when comparing short and long-term outcomes. This systematic review/meta-analysis pooled study data and compared clinical outcomes: Harris Hip Score, WOMAC score, and Oxford hip score, along with radiological and complication outcomes. The results of this analysis found that MIS does not perform significantly better for any outcome and presents with increased risk of iatrogenic nerve injury during the procedure.
