Interobserver and Intraobserver Reliability of the Modified Waldenstrom Classification System for Staging of Legg-Calve-Perthes Disease

Conclusions:
The modified Waldenström classification system for staging of Legg-Calvé-Perthes disease demonstrated substantial to almost perfect agreement between and within observers across multiple rounds of study. In doing so, the results of this study provide a foundation for future validation studies, in which the classification stage will be associated with clinical outcomes.
