Abstract

Aims: Evaluate the results of MD-collagen injection therapy in the treatment of supraspinatus tendonitis under ultrasound guidance and evaluate adverse effects of this therapy after 12 weeks of follow-up. Methods: Controlled clinical trial were followed up to 12 weeks in 61 patients with supraspinatus tendonitis,divided into two groups: 30 patients received 5 times in 5 consecutive weeks’sultrasound-guided injection of Collagen MD-Shoulderinto the subacromial bursa, 31 patientswere given a single ultrasound-guided injection of Depo-Medrolinto the subacromial bursa. Results: After 12 weeks of treatment, there was an improvement in VAS, OSS scores, shoulder range of motion in the research group: The average VAS were decreased from 6.8 to 2.5 points (reduction rate compared to T0 is 63.9%.), OSS scores were increased from 23,5 ± 4,9 to 39,7 ± 6,9 points (the rate of increase compared to T0 is 39.4%)higher than the placebo group (p<0,05), shoulder range of motion increased from 147,83 to 171,30 (the rate of increase compared to T0 is 20,6%). Side effects of the research group was 13.3% of the patients increased pain at the injection. Conclusion: MD-Shoulder collagen injection therapy under ultrasound guidance in the treatment of supraspinatus tendonitis has the effect of reducing pain, improving motor function and angle of motion after 12 weeks of treatment. Ultrasound-guided MD-Shoulder Collagen Injection therapy had similar analgesic effect, but improved shoulder mobility better than Depo-Medrol injection therapy from 5 weeks, lasting up to 12 weeks of treatment (p < 0.05).
