Meta Analysis On The Clinical Effect Of Minimally Invasive Versus Conventional Incision For Total Hip Arthroplasty

OBJECTIVE:To assess the effect of Minimally Invasive compared with Conventional Incisionfor Total Hip Arthroplasty.Methods:A computer-based online search of PubMED and Ovid database published from2002～2011,which were performed to collect randomized controlled trials ofMinimally Invasive compared with Conventional Incision for Total Hip Arthroplasty.Data were evaluated by RevMan5.0.1for Meta analysis.RESULTS:Total14related papers were included, Meta-analysis indicates that comparedwith conventional incision, minimally invasive incision for total hip arthroplastycould reduce the amount of intraoperative blood loss, the amount of total blood loss,the VAS score and the hospital stay.There is no difference in the rate ofcomplications and operative time. As for the aspect of hip function after THA，TheHHS score of MIS is better than the conventional incision within one year.CONCLUSION：The hip function was better in the MIS for less blood loss, hospital stay andpostoperative rehabilitation. However, more high-quality studies are required tocompare the outcomes of these two procedures.
