Abstract:

BACKGROUND: Hip surface replacement has been widely used in recent years, but there is great controversy on which works better, hip surface replacement or traditional total hip arthroplasty.
OBJECTIVE: To investigate and compare the advantages and disadvantages of hip surface replacement and total hip arthroplasty trough compressive analyzing the published literatures.
METHODS: The randomized controlled trials on the hip surface replacement and total hip arthroplasty from January 1900 to July 2012 were retrieved. The quality of the included randomized controlled trials was evaluated strictly. The RevMan5.1.6 was used for Meta-analysis
RESULTS AND CONCLUSION: Ten randomized controlled trials were included. Results of Meta-analysis showed that there were no significant differences in operation time, intraoperative blood loss, 1 year postoperative Harris score, 1 year postoperative University of California at LosAngeles hip function score and serum levels of cobalt and chromium ion at 2 years after replacement between hip surface replacement and total hip arthroplasty. The average acetabulum anteversion angle in the hip surface replacement group was greater than that in the total hip arthroplasty group. The results indicate that there was no significant difference in the short-term follow-up between hip surface replacement and total hip arthroplasty, but the long-term effect needs to be evaluated with higher quality and larger sample clinical randomized controlled trials.
