Background:
Whether there is any clinical superiority for the two-incision total hip arthroplasty (THA) over the mini-posterior THA remains controversial. The present meta-analysis aimed to comprehensively compare the clinical outcomes between the two mini-invasive THAs.
Methods:
Two authors searched the database of Web of Science, PubMed, EMBASE and Cochrane Library to screen eligible studies individually. The quality evaluation of included studies was performed according to the principle of risk-of-bias of the Cochrane Library. The pooled results were analysed by Review Manager 5.3 software.
Results:
A total of seven prospective studies (including five randomized controlled trials) with 423 hips were finally included for meta-analysis. The pooled results revealed that the mini-posterior THA outperformed the two-incision THA in shortening operative times, reducing blood loss and postoperative fracture risks, while no significant difference was found between the two surgery methods with respect to HSS scoring, SF-12 scoring, postoperative function recovery and other postoperative complications.
Conclusion:
Based on the pooled results, we suggested the mini-posterior THA as a preferable choice for patients suffering from severe advanced hip diseases.
