Although evidence of increased effectiveness is lacking, attempting to accurately administer steroid injections to their target location is still considered standard of care. Point-of-care ultrasonography can be helpful when training health care professionals to see and feel where the injection is going. Various pathologies also can be visualized with ultrasonography. A four-minute video of a clinician performing ultrasonography of shoulder structures and administering a subacromial injection is available at http:///watch?v=Z161HyusPhg&feature=related .

MAIN OUTCOME MEASUREMENTS:Perceived improvement in symptoms at least 6 months after treatment, perceived change in visual analog scale score, assessment of functional pain, and overall satisfaction.
On average, patients were 48 years old, had symptoms for a median of 18 months before treatment, and answered the survey on average 15 months after treatment. Overall, 82% of patients indicated moderate to complete improvement in symptoms. The most common injection sites were the lateral epicondyle, Achilles, and patellar tendons. Other sites treated included the rotator cuff, hamstring, gluteus medius, and medial epicondyle, among others. Furthermore, 60% of patients received only 1 injection, 30% received 2 injections, and 10% received 3 or more injections. Patients' perceived decrease in visual analog scale score was 75%, from ± to ± (-, SD , 95% confidence interval - to -, P < .0001). In addition, at follow-up, 95% of patients reported having no pain at rest that disrupted their activities of daily living and 68% reported no pain during activities. A total of 85% of patients were satisfied with the procedure.
In this retrospective study, in which we evaluated administration of PRP for chronic tendinopathy, we found that the majority of patients reported a moderate (>50%) improvement in pain symptoms.
