Despite being a self-limiting injury, lateral epicondylitis (LE) can be difficult to manage. In cases of refractory LE, conservative treatment fails and symptoms persist over 6 months. Previous studies have investigated the role of botulinum Toxin Type A (BoNT-A) injections in LE with controversial results. There is some evidence that repeating the BoNT-A injection could be beneficial for refractory cases. The objective is to assess the success rate of one or two BoNT-A injections for refractory LE.
