In total hip arthroplasty (THA), the direct anterior approach (DAA) has more advantages than the posterior approach (PA), including superior rehabilitation outcomes. This study was to evaluate the recovery of \u201cprosthesis awareness\u201d through these two approaches.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Three hundred and seventy\u2010six patients who received THA with either DAA (n\u00a0=\u00a041) or PA (n\u00a0=\u00a0335) from January 2016 to December 2017 were retrospectively analyzed. The Forgotten Joint Score\u201012 (FJS\u201012), Harris hip score (HHS), and visual analog scale (VAS) analyses were used to evaluate the recovery of \u201cprosthesis awareness\u201d in these patients 2\u2009weeks, 1, 3, 6, and 12\u00a0months after surgery. The student <jats:italic>t<\/jats:italic>\u2010test, Wilcoxon rank sum test, chi\u2010square test, and MANOVA were used to compare the differences among groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We found that DAA patients had higher FJS\u201012 scores than PA patients at 2\u2009weeks (42.15\u2009\u00b1\u20093.36 vs. 38.09\u2009\u00b1\u20093.28, <jats:italic>p\u2009=<\/jats:italic>\u00a00.042), 1\u2009month (49.06\u2009\u00b1\u20095.14 vs. 41.11\u2009\u00b1\u20095.21, <jats:italic>p\u2009=<\/jats:italic>\u00a00.038), and 3\u2009months (53.23\u2009\u00b1\u20094.07 vs. 48.09\u2009\u00b1\u20093.71, <jats:italic>t<\/jats:italic>\u00a0=\u00a03.152, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.045). And the recovery rates of FJS\u201012 scores in DAA and PA groups at 2\u2009weeks, 1\u2009month, and 3\u2009months after surgery were 75.46%\u2009\u00b1\u20096.04%, 84.05%\u2009\u00b1\u20096.57%, 91.37%\u2009\u00b1\u20097.13%, and 74.14%\u2009\u00b1 5.54%, 78.16%\u2009\u00b1\u20096.01%, 88.23%\u2009\u00b1\u20096.42%, respectively. To compare the recovery effects of the two procedures in more detail, we classified the 12 items in FJS\u201012 that evaluate different types of gravity center motions into three categories: low\u2010movement group (LG), middle\u2010movement group (MG), and high\u2010movement group (HG). Interestingly, DAA patients had significantly higher HG than PA patients at 2\u2009weeks, 1\u2009month, and 3\u2009months after operation (<jats:italic>t<\/jats:italic>\u00a0=\u00a03.225, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.022 at 2\u2009weeks, <jats:italic>t<\/jats:italic>\u00a0=\u00a03.081, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.041 at 1\u2009month and <jats:italic>t<\/jats:italic>\u00a0=\u00a02.783, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.046 at 3\u2009months), whereas no significant differences were observed in LG\u2010 and MG\u2010related items. In addition, there were no significant differences in HHS and VAS scores between DAA and PA patients at 2\u2009weeks (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.102, <jats:italic>p\u2009=<\/jats:italic>\u00a00.093), or from 1\u2009month to 12\u00a0months (each
