This trial, like all surgical RCTs, have some limitations that cannot be avoided. First, although all surgeons are fellowship trained and considered to be experts in hip arthroscopy and the treatment in FAI, there are differences in surgical techniques and intra-operative decision making that cannot be normalized. However, this also makes the results of this RCT more generalizable. Also, as with any RCT, the surgeons cannot be blinded to the treatment allocation.
