Botulinum neurotoxin-A in idiopathic chondrolysis: a report of two cases

Abstract

Two cases of idiopathic chondrolysis were treated by botulinum neurotoxin-A injections, with a favorable outcome. The treatment consisted of botulinum neurotoxin-A injections, followed by an intensive rehabilitation program. No surgery was needed. Both patients were symptom-free and showed an extremely satisfactory range of motion. Radiographs indicated reconstitution of the joint space in both cases. We believe that botulinum neurotoxin-A injections combined with an intensive rehabilitation program may be considered a new potential management modality and is worth attempting and studying when one considers the results of previously published reports.
