Botulinum Injection in the Tensor Fasciae Latae as an Adjunct Treatment for Iliotibial Band Syndrome

Abstract

Iliotibial band syndrome is a highly prevalent and painful condition characterized by anterolateral knee pain from an inflamed iliotibial band, with the current standard of care being physical therapy. However, we lack sufficient adjunct treatment options for patients with refractory iliotibial band syndrome who fail physical therapy. This study will evaluate the efficacy and safety of using botulinum toxin type A injections into the tensor fasciae latae as an adjunct therapy for patients with refractory iliotibial band syndrome. With all patients receiving the same physical therapy treatment, we randomized patients to the control group of saline injection and to the treatment group of botulinum toxin type A injection. Successful use of botulinum injections will lead to significant improvement in pain and function in patients with refractory iliotibial band syndrome and open the door for its use in other muscle imbalance syndromes
