The aim of current analysis was to apply an explicitly defined sub-group analysis to confirm whether this hypothesis is true. Methods A computerized literature search was applied to find any data concerning MIS or mini-incision THAs. A multistage screening was then performed to identify randomized studies fulfilling the inclusive criteria for the analysis. The data were extracted, and sub-group analyses of MIS or mini-incision surgery for different kinds of outcomes were carried out. The P（sub） value for difference between MIS sub-group and mini-incision sub-group was also calculated. Results Eleven studies that fulfilling the inclusion criteria were included, with 472 cases in the study group （MIS or mini-incision） and 492 cases in the conventional group. The overall analysis showed the study group would achieve less surgical duration （P=0.037）, intraoperative blood （P 〈0.001） and incision length （P 〈0.001） than conventional group. The difference between sub-groups showed, the MIS would achieve shorter incision length （P（sub） 〈0.05） and bigger cup abduction angle （P（sub） 〈0.05）, and cause more blood loss （P （sub） 〈0.05） than mini-incision technique. Other indexes were comparable between the two sub-groups. Conclusions Though further high quality studies are still needed, the result of current analysis offered an initial conclusion that MIS THA failed to achieve a better clinical outcome than mini-incision technique. The exact definition of MIS still needs to be improved.展开更多
