Why was this study needed now?
Arthroscopic acromioplasty continues to be used in the management of patients with shoulder impingement even though recent evidence has suggested that this treatment provides no significant advantages in clinical and functional outcomes in comparison to exercise therapy. Proponents of this treatment have suggested that the benefit of acromioplasty may lie in preserving rotator cuff muscle integrity and volume. A randomized controlled trial was needed to evaluate outcomes on MRI following acromioplasty, as compared to exercise therapy alone.
What was the principal research question?
In patients with shoulder impingement syndrome, does arthroscopic acromioplasty significantly affect the rate of eventual rotator cuff tear on imaging, or volumes of the rotator cuff muscles, when compared to a structured exercise program alone over a 5-year follow-up?
|Population:||140 patients with stage II shoulder impingement syndrome|
|Intervention:||Acromioplasty + exercise group: Patients underwent arthroscopic acromioplasty, followed by an exercise therapy program. (n=70)|
|Comparison:||Exercise alone group: Patients participated in structured exercise therapy program. (n=70)|
|Outcomes:||MRI was performed to assess muscle volume change, the incidence of supraspinatus tendon rupture, and grade muscle fatty degeneration.|
|Time:||MRI was performed at 5 year follow-up|
