A brief history of Legg-Calvé-Perthes disease.

Legg-Calvé-Perthes (LCP) disease has an extensive history that has provided an ongoing intellectual challenge for the orthopaedic community. Debate around etiology and treatment of LCP disease continues even after its initial description in the early 1900 s. In order for modern day clinicians to have a full understanding of the condition, one must be a scholar of its development. The purpose of our review will be to discuss the scientific communities' understanding of presentation, etiology, and treatment of LCP disease over time.
