CORTICOSTEROID INJECTIONS FOR ROTATOR CUFF TEARS
The use of a single injection of corticosteroids with local anesthetic can be considered for short-term improvement in both pain and function for patients with shoulder pain. In patients who cannot tolerate corticosteroids, injectable NSAIDs may be considered.

Rationale

Multiple high- and moderate-quality studies indicate that corticosteroid (CS) injections for patients with rotator cuff pathology are beneficial with regards to pain (VAS/SPS) level reduction (Moosmayer 2023; ElGendy 2023; Daghiani, 2023; Raeesi, 2022; Lee, 2022; Hopewell, 2021; Ekeberg, 2009; Alvarez, 2005; Kang, 2016; Abolhasani 2019; Hsieh, 2021; Carroll, 2018; Boonard, 2018; Sari, 2020; Babaei-Ghazani, 2019; Darrieutort-Lafitte, 2019; Liu, 2019; Louwerens, 2020; Holt, 2013; Eyigor, 2010; Penning, 2012; Atar, 2023; Hsieh, 2023; Hajivandi, 2021; Vergili, 2021; Apivatgaroon, 2023; Pasin, 2019; Ebadi, 2023; Dogan, 2021; Battaglia, 2017; Lee, 2017; Rabini, 2012; Lin, 2014).

Moosmayer et al (high quality study) demonstrated improved QuickDash and EQ-5D-5L outcomes at 1.5 months after corticosteroid injection, but not at 4, 8, 12, 24 months. When compared to physical therapy (PT), corticosteroid injections provided better QuickDash/SPADI/WORC scores (Daghiani, 2023). These studies indicate short-term benefit regarding pain level and function. Due to the heterogeneity of patient-reported outcomes and variability of study findings, the strength of the recommendation was downgraded to moderate.

Risks and Harms of Implementing this Recommendation
Corticosteroid injections in the setting of rotator cuff tears may be detrimental to the healing potential following rotator cuff repair. Considering that rotator cuff diagnoses are clinical, a single corticosteroid injection may be given to confirm the presence of a symptomatic rotator cuff tear but may adversely affect outcomes if performed in temporal proximity to surgical intervention.

Future Research
Further research is recommended to determine the role of corticosteroid injections in the various settings of rotator cuff pathology.
