The purpose of this study was to examine the progression of clinical outcomes 3, 6 and 12 months after hip arthroscopy with labral repair for femoroacetabular impingement (FAI).


From May 2009 to December 2011, 87 consecutive patients [55 females (median age 38, range 17–63) and 32 males (median age 38, range 15–59)] underwent hip arthroscopy and labral repair, by the same experienced surgeon. Standardised, but unstructured, post-operative rehabilitation instructions were provided. Function and pain were evaluated using modified Harris Hip Score (mHHS) and visual analogue scale (VAS) pre-operatively and post-operatively at 3, 6, and 12 months.


A main effect of time was seen for mHHS and pain (VAS) at 3, 6, and 12 months (p < 0.001). Mean (SE) mHHS improved significantly from 59.9 (1.9) pre-operatively to 74.5 (1.9) after 3 months (p < 0.001), and again from 3 to 6 months from 74.5 (1.9) to 80.1 (1.9) (p = 0.004), with no additional changes from 6 to 12 months [80.1 (1.9)–78.7 (1.9), (n.s.)]. Also, the mean (SE) VAS improved significantly from pre-operative 57.9 (2.6) to 30.0 (2.6) after 3 months (p < 0.001), and from 30.0 (2.6) to 22.6 (2.6) (p = 0.017), after 6 months with no additional changes from 6 to 12 months [22.6 (2.6)–27.9 (2.6), (n.s.)].


Improvements in function (mHHS) and pain (VAS) were seen in patients after hip arthroscopy with labral repair for FAI at 3, 6, and 12 months. While significant improvements occurred from 3 to 6 months, no further improvements were seen from 6 to 12 months.
