Does Limb Pre-Conditioning Reduce Pain After Hip Arthroscopy

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine if the utilization of Ischemic Pre-Conditioning 24-hours prior to hip arthroscopy decreases patient's post-operative pain and opioid consumption.

Detailed Description
-----------------
Subjects will be asked to take part in one of two treatment procedures 24 hours prior to their scheduled hip arthroscopy date. Subjects will be randomized into either the IPC or CON group. These treatments consist of either 3 rounds of 5 minutes of occlusion alternating with 5 minutes of reperfusion or 3 rounds of 5 minutes of minimal occlusion alternating with 5 minutes of reperfusion. The treatment will last 30 minutes. Days 0-7 post-op will consist of self-reported pain scales and opioid consumption documentation in the morning and evening. This is a randomized single-blind research study. This study has two study groups: The IPC group will get a standardized pre-conditioning treatment 24 hours prior to their hip arthroscopy. This consists of 3 rounds of 5 minutes of occlusion alternating with 5 minutes of reperfusion while seated. The CON group will get a controlled treatment of 20% of limb occlusion pressure 24 hours prior to their hip arthroscopy. This consists of 3 rounds of 5 minutes of minimal occlusion alternating with 5 minutes of reperfusion while seated.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: The IPC group<br>subjects will get a standardized pre-conditioning treatment 24 hours prior to their hip arthroscopy. This consists of 3 rounds of 5 minutes of occlusion alternating with 5 minutes of reperfusion while seated. | Diagnostic Test: standardized pre-conditioning treatment<br>* 3 rounds of 5 minutes of full occlusion alternating with 5 minutes of reperfusion while seated.<br>|
| Other: The CON group<br>subjects will get a controlled treatment of 20% of limb occlusion pressure 24 hours prior to their hip arthroscopy. This consists of 3 rounds of 5 minutes of minimal occlusion alternating with 5 minutes of reperfusion while seated. | Diagnostic Test: Partial occlusion<br>* 3 rounds of 5 minutes of partial occlusion alternating with 5 minutes of reperfusion while seated.<br>|
