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.
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.

Change in Patient Satisfaction and Functional Outcome
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.
Time frame: Baseline and 6 weeks, 12 weeks, and 6 months postoperatively
Analgesic Usage
Analgesic usage measured via the morphine-equivalent dose of consumed analgesic medications
Time frame: Initial two postoperative weeks
Pain Level
Change in pain level measured on a Likert-type scale from 0 to 10, with higher scores representing higher pain levels.
Time frame: Initial two postoperative weeks
