However, corticosteroid injection does not completely al- leviate the pain (average pain reduction 55 % [4]), and medium- and longer-term responses are much lower than its initial effects. Positive responses drop to 41–55 % at 3–4 months [1, 2, 54], and after 12 months, Brinks et al. [1] showed no difference in outcomes between subjects receiving corticosteroid injection and those receiving usual care (analgesics as required). This pattern of poorer out- comes in the longer term, with high rates of recurrence, has been shown for other insertional tendinopathies, such as tendinopathy of the lateral elbow [75, 76].
