Reliability of a Modified Watson-Jones Classification for Tibial Tubercle Fractures in Children

The first case report describing a pediatric fracture of the tibial tubercle was published in 1852 in the Medical Times and Gazette, a Journal of Medical Science, literature, criticism, and news. A century later, in 1955, Sir Watson-Jones introduced the first classification system for this fracture. Despite the existence of several classification systems for pediatric tibial tubercle fractures in the medical literature, a crucial aspect of their validation-reliability and reproducibility-has not yet been systematically evaluated.
