OBJECTIVE: To determine whether ultrasound-guided platelet-rich plasma (PRP)
injections are an effective treatment for chronic tendinopathies. DESIGN:
A retrospective, cross-sectional survey. SETTING: Four academic sports medicine
centers from across the United States. PATIENTS: A total of 180 men and women
between the ages of 18 and 75 years who received ultrasound-guided PRP injections
for tendinopathy refractory to conventional treatments. INTERVENTIONS: Survey on
satisfaction and functional outcome. MAIN OUTCOME : Perceived
improvement in symptoms at least 6 months after treatment, perceived change in
visual analog scale score, assessment of functional pain, and overall
satisfaction. RESULTS: 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 7.0 +/- 1.8 to 1.8 +/- 2.0 (-5.2, SD
2.7, 95% confidence interval -5.65 to -4.86, 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. CONCLUSIONS: 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.
