Hoffa's Disease in a Modern Dancer Case Report and Literature Review.

We present the case of a modern dancer at the university level with left knee pain as a result of Hoffa's disease. A comprehensive literature review of Hoffa's disease indicates that it may be an under-recognized condition. Predisposing factors in dance training include torsion and hyperextension at the knee, particularly in conjunction with pelvic instability and weakness. Clinicians should be cognizant of this differential diagnosis when evaluating dancers with knee pain. We present a detailed progressive rehabilitation protocol including transitional interventions for Hoffa's disease in the dancer.
