Brief Summary:
The purpose of this study is to measure whether CPM (continuous passive motion) usage improves outcomes following arthroscopic hip surgery that includes labral repair. Investigators tested the hypothesis that CPM usage reduces pain levels and pain medication use and improves function in individuals who undergo hip arthroscopy.

Condition or disease Intervention/treatment Phase
Femoro Acetabular Impingement Pain, Postoperative Hip Labral Tear Device: Continuous Passive Motion Not Applicable

Detailed Description:
Subjects undergoing primary hip arthroscopy for acetabular labral repair were randomized to determine whether they would receive a CPM. Those subjects receiving a CPM were instructed to use it for 4-6 hours daily throughout the first two postoperative weeks. The total number of pain medications and average pain scores over the two weeks, as well as Hip Outcome Score Activity of Daily Living (HOS ADL) scores at standard time points were compared via a two sample t-test and intention-to-treat analysis.

Official Title: The Effect of Continuous Passive Motion on Pain Control Following Hip Arthroscopy

Arm Intervention/treatment
Active Comparator: CPM
These subjects received a continuous passive motion (CPM) device and were instructed to use it for 4-6 hours daily throughout the first two postoperative weeks following their arthroscopic labral repair. They were provided adequate education on how to operate the device. The subjects recorded their average usage of the CPM, as well as their personal perception of the CPM, at the postoperative 2 day, 7 day, and 14 day marks.
Device: Continuous Passive Motion
CPM devices are used in postoperative rehabilitation and are throughout to reduce joint stiffness.

No Intervention: No CPM
No CPM was administered to these subjects.

Primary Outcome Measures :
  1. Change in Patient Satisfaction and Functional Outcome [ Time Frame: Baseline and 6 weeks, 12 weeks, and 6 months postoperatively ]
    Hip Outcome Score Activities of Daily Living (HOS ADL) questionnaire completed at specific time points. Completion of the HOS ADL provides a score from 0 to 100, with a higher score corresponding to greater level of function. The improvement preoperative to 6 month postoperative scores was also computed.

Secondary Outcome Measures :
  1. Analgesic Usage [ Time Frame: Initial two postoperative weeks ]
    Analgesic usage measured via the morphine-equivalent dose of consumed analgesic medications

  2. Pain Level [ Time Frame: Initial two postoperative weeks ]
    Change in pain level measured on a Likert-type scale from 0 to 10, with higher scores representing higher pain levels.
