The Use of Ultrasound-Guided Injections for Tendinopathies
Purpose of Review
The purpose of the study was to review the efficacy and safety of common ultrasound-guided injections for tendinopathy conditions. Corticosteroid injections have historically been the most common injection used for tendinopathy; however, there are an increasing number of injections including platelet-rich plasma, hyaluronan, polidocanol, botulinum toxin, and high volume saline injections.
There is growing evidence that while corticosteroid injections for tendinopathies usually have short-term efficacy, they may result in medium-term harm, particularly for tennis elbow (lateral epicondylitis). Corticosteroid injections appear to have more clinical utility for tenosynovitis conditions. There is insufficient evidence regarding other injection options to make a broad recommendation in favour, although individual trials for certain tendons illustrate benefits for some of the non-corticosteroid options.
When considering the use of ultrasound-guided corticosteroid injections for tendinopathies, the risk of possible medium-term harm must be weighed up against any short-term efficacy. Other injection-based therapies may be appropriate in certain clinical situations; however, the evidence and clinical circumstances must be considered for the particular tendon and patient. Load-based rehabilitation remains the cornerstone of tendinopathy management.
