简要总结
This prospective, randomized, double-blind controlled clinical trial aims to compare the clinical and ultrasonographic outcomes of intralesional and perilesional 5% dextrose injection in patients with partial rotator cuff tears. Eligible participants will be randomized into two parallel groups. Both groups will receive ultrasound-guided 5% dextrose injection to the supraspinatus enthesis. In addition, one group will receive intralesional 5% dextrose injection, while the other group will receive perilesional 5% dextrose injection using the peppering technique. Injections will be performed in three treatment sessions at 21-day intervals. All participants will receive a home-based exercise program after completion of the injection treatments. Clinical outcomes will be assessed at baseline, 9 weeks, and 12 weeks after treatment, and ultrasonographic outcomes will be assessed at baseline and 12 weeks.
详细描述
Rotator cuff tears are one of the leading causes of shoulder pain and functional limitation. Partial rotator cuff tears may become chronic and may not respond adequately to conventional conservative treatments such as activity modification, physical therapy, and nonsteroidal anti-inflammatory drugs.
Dextrose injection is a regenerative injection therapy that aims to stimulate tissue healing responses in chronic musculoskeletal disorders. It is thought to promote fibroblast activation, collagen synthesis, and proliferative healing processes in degenerative tendon, ligament, and enthesis lesions. Ultrasound guidance allows accurate and safe delivery of the injectate to the target tissue and enables objective follow-up of tendon morphology during the treatment process.
This study will include adult patients with partial rotator cuff tears diagnosed by clinical examination and imaging. Participants will be randomized into two groups using a computer-based random number system. The researcher performing the randomization will know the treatment allocation, while the participants and the physician assessing the clinical outcomes will be blinded to treatment groups.
Both groups will receive ultrasound-guided 5% dextrose injection to the supraspinatus enthesis. The intralesional group will additionally receive intralesional 5% dextrose injection, and the perilesional group will additionally receive perilesional 5% dextrose injection. Injections will be applied using the peppering technique, with 0.1-0.2 cc administered to each point. A total of three treatment sessions will be performed at 21-day intervals.
Clinical outcomes will include shoulder pain assessed by the Numeric Rating Scale, shoulder pain and disability assessed by the Shoulder Pain and Disability Index, and health-related quality of life assessed by the Short Form-12 Health Survey. Ultrasonographic outcomes will include supraspinatus tendon thickness and partial defect size. Clinical evaluations will be performed at baseline, 9 weeks, and 12 weeks after treatment. Ultrasonographic evaluations will be performed at baseline and 12 weeks.

结局指标
主要结局
Change in Shoulder Pain Intensity Assessed by Numeric Rating Scale
时间窗: Baseline, 9 weeks, and 12 weeks after treatment
Shoulder pain intensity will be assessed using the Numeric Rating Scale. Night pain, worst daytime shoulder pain, and average shoulder pain will be evaluated on a 0-10 scale, where 0 indicates no pain and 10 indicates the worst pain imaginable. Higher scores indicate greater pain intensity.
次要结局
- Change in Shoulder Pain and Disability Assessed by the Shoulder Pain and Disability Index(Baseline, 9 weeks, and 12 weeks after treatment)
- Change in Health-Related Quality of Life Assessed by the Short Form-12 Health Survey(Baseline, 9 weeks, and 12 weeks after treatment)
- Change in Supraspinatus Tendon Thickness Assessed by Ultrasonography(Baseline and 12 weeks after treatment)
- Change in Partial Rotator Cuff Defect Size Assessed by Ultrasonography(Baseline and 12 weeks after treatment)
