Comparing Two Ultrasound-Guided 5% Dextrose Injection Methods for Partial Rotator Cuff Tears in Adults A Randomized, Double-Blind Clinical Trial

What this Trial Is About

This research aims to compare the effects of two types of 5% dextrose injections for adults with partial rotator cuff tears, a common cause of shoulder pain and limited movement. The study is a randomized, double-blind clinical trial that investigates whether injecting dextrose directly into the tear or around it leads to better healing and pain relief. Participants will be adults diagnosed with partial rotator cuff tears confirmed by clinical exams and imaging. Participants will be randomly assigned to one of two groups. Both groups will receive ultrasound-guided injections of 5% dextrose to the supraspinatus enthesis using a peppering technique. One group will receive injections inside the torn tendon area intralesional, while the other group will receive injections around the tear perilesional. Each participant will have three injection sessions spaced 21 days apart. After completing injections, all participants will follow a home-based exercise program. Throughout the study, clinical assessments will measure shoulder pain intensity, pain and disability levels, and quality of life at the start, 9 weeks, and 12 weeks after treatment. Ultrasound will be used to evaluate tendon thickness and tear size at the start and 12 weeks later. Participants will be monitored for these outcomes to understand the treatment effects and recovery progress over approximately three months.
