Subacromial Decompression Versus Diagnostic Arthroscopy for Shoulder Impingement .
High Impact
This study has been identified as potentially high impact. OE's AI-driven High Impact metric estimates the influence a paper is likely to have by integrating signals from both the journal in which it is published and the scientific content of the article itself. Developed using state-of-the-art natural language processing, the OE High Impact model more accurately predicts a study's future citation performance than journal impact factor alone. This enables earlier recognition of clinically meaningful research and helps readers focus on articles most likely to shape future practice.

Subacromial decompression versus diagnostic arthroscopy for shoulder impingement: a 5-year follow-up of a randomised, placebo surgery controlled clinical trial

Br J Sports Med. 2021 Jan;55(2):99-107.

Two hundred ten patients with shoulder impingement syndrome were randomized to receive either arthroscopic subacromial decompression (ASD) (n=59), diagnostic arthroscopy (n=63), or exercise therapy (n=71). The primary outcomes of interest were shoulder pain at rest and on arm activity, measured using a Visual Analogue Scale (VAS). Secondary outcomes included Constant-Murley score, Simple Shoulder Test score, SF-36, and 15D health-related quality of life measures. Outcomes were assessed over five years. Overall, the results of the study revealed no clinically significant differences between ASD and diagnostic arthroscopy, nor between ASD and exercise therapy, in reducing shoulder pain or improving function. The study suggests that ASD does not provide additional benefits over diagnostic arthroscopy or structured exercise therapy in the long term.
