The same number of age\u2010 and gender\u2010matched FAI syndrome patients without ESH undergoing hip arthroscopy were enrolled in the control group (FAI group). Patient\u2010reported outcomes (PROs) including international Hip Outcome Tool (iHOT\u201033), modified Harris Hip Score (mHHS), visual analog scale for pain (VAS\u2010pain), and abductive force of affected hip at 3\u2009month and 2\u2009years postoperatively were comparatively analyzed. The VAS\u2010satisfaction score of two groups at 2\u2009years postoperatively were also analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The prevalence of ESH in FAI syndrome patients undergoing hip arthroscopy in our institution was 5.5% (39 of 715 hips), including nine males (10 hips) and 29 females (29 hips). The mean age at the time of surgery was 32.1 \u00b1\u20096.9\u2009years (range, 22\u201348\u2009years). According to inclusion and exclusion criteria, 23 patients were enrolled in FAI + ITB group. Twenty\u2010three age\u2010 and sex\u2010matched FAI syndrome patients were enrolled in FAI group. At 24\u2009months postoperatively, no patient still suffered ESH symptoms and painful palpation at lateral region in FAI + ITB group. The iHOT\u201033, mHHS, and VAS\u2010pain score of patients in FAI + ESH group were significantly severer than patients in FAI group preoperatively (41.6 \u00b1\u20097.5 <jats:italic>vs<\/jats:italic> 48.8 \u00b1\u20097.2, 54.8 \u00b1\u20097.2 <jats:italic>vs<\/jats:italic> 59.2 \u00b1\u20096.9, 5.5 \u00b1\u20090.9 <jats:italic>vs<\/jats:italic> 4.7 \u00b1\u20091.0; <jats:italic>P<\/jats:italic> &lt;\u20090.05), while there was no significant difference in these scores between the patients in FAI + ESH group and FAI group at 3\u2010month and 24\u2010month follow\u2010up (73.6 \u00b1\u20098.5 <jats:italic>vs<\/jats:italic> 76.1 \u00b1\u20096.9, 85.3 \u00b1\u20097.8 <jats:italic>vs<\/jats:italic> 84.2 \u00b1\u20096.6, 0.8 \u00b1\u20090.9 <jats:italic>vs<\/jats:italic> 0.6 \u00b1\u20090.9; <jats:italic>P<\/jats:italic> &gt;\u20090.05). At 3\u2009months after surgery, the abductive force of operated hip was significantly smaller than that in FAI group (82.4 \u00b1\u200912.4 N <jats:italic>vs<\/jats:italic> 91.9 \u00b1\u200916.1 N, <jats:italic>P<\/jats:italic> &lt;\u20090.05), whereas there was no significant difference at 24\u2009months after surgery (101.6 \u00b1\u200914.9 N <jats:italic>vs<\/jats:italic> 106.5 \u00b1\u200913.7 N, <jats:italic>P<\/jats:italic> &gt;\u20090.05).
