SporTRIA Study: A Multicentre Trial for Excretion Kinetics of Triamcinolone Acetonide Following Sport Related Intra-articular Injections in Knees; Definitions of the Washout Periods

Intra-articular and peri-articular glucocorticoid (GC) injections are common in sports medicine. However, from 1st January 2022, all injectable GC routes (including intra-articular administration (IA)) will be prohibited in-competition by World Anti-Doping Agency (WADA). Due to these rules, an IA GC treatment out-of-competition could result in an adverse analytical finding (AAF) in-competition if the washout period is not clearly defined. The aim of this study is to determine the urinary excretion profile of triamcinolone acetonide following IA to help in the definition of the washout periods.
