This study will be a randomized, double-blinded, placebo controlled study. All patients who are scheduled to undergo a hip arthroscopy with Dr. Yen who meet the inclusion/exclusion criteria will be approached and informed consent and assent when indicated would be obtained.Attending surgeon, anesthesia care team, PACU nursing staff, inpatient ward nursing staff and evaluators will be blinded to study group. Regional Anesthesia team and pharmacy staff will be not blinded to assignment of patient group but will have no additional contact with patient after provision of sham or actual perineural catheter. the study design will be real catheter versus a sham catheter, or control. All subjects will receive general anesthesia. The catheters (real or sham) will be administered after the induction of general anesthesia and before the beginning of the surgery until 24 hours after recorded PACU admittance time. The anesthesia team placing the block will not be blinded. The orthopaedic surgeon (Dr. Yen) and all evaluators will be blinded to the absence or presence of a real catheter. In the case of a sham catheter, the anesthesia team will rig a pump to look like it is dispensing local anesthesia.
