Fluoroquinolone-induced Achilles tendinitis: a case report.

Abstract

Although most cases of Achilles tendinitis are caused by some form of biomechanical stress, other factors may play a role in its etiology. Fluoroquinolone use is a well-known contributing factor to Achilles tendon pathology. This report describes a case of fluoroquinolone-induced Achilles tendinitis in a 77-year-old woman. Eight weeks after she presented to our office, the patient reported significant improvements after a course of care that included low level laser therapy (LLLT), activity modification and graduated exercises. Management can include many of the treatment tools used for biomechanically induced tendinopathy, with particular consideration given to delaying more advanced weight-bearing rehabilitative exercise due to the increased risk of rupture.
