About

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.

Full 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.

54 participants in 2 patient groups

CPM

Active Comparator group

Description:

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.

Treatment:

Device: Continuous Passive Motion

No CPM

No Intervention group

Description:

No CPM was administered to these subjects.
