the purpose of the article is to produce a French-Canadian translation of the "OA Go Away" tool and to assess the validity of its contents as well as its test-retest reliability. "OA Go Away" is a customized tool that measures the various symptoms, their impact, and the physical activities of people with osteoarthritis of the hip or knee to improve self-care and help them be physically active. Vallerand's cross-cultural validation methodology was used. First, professional translators and rehabilitation professionals produced a parallel reverse translation of the "OA Go Away" tool. Then, a committee of experts examined the translated versions and created a first experimental draft of the "Au revoir arthrose" tool. This draft was assessed and modified by a second committee of experts. Three users with osteoarthritis of the knee then assessed this version. Finally, a linguist examined the draft and an expert produced a final reverse translation of that version. The main co-researchers proposed final modifications of that version. Twenty-one users indicated that the wording of the final "Au revoir arthrose" version was clear. The test-retest reliability was acceptable for the main elements of the "Au revoir arthrose" journal. The process's five rigorous steps enabled the creation of a valid French-Canadian version of the "Au revoir arthrose" tool. On average, the French-Canadian version of the "Au revoir arthrose" tool has moderate test-retest reliability for all of its elements. This tool can prove to be relevant for people suffering from osteoarthritis of the hip or knee, motivating them to be physically active, and for the health professionals who care for them.
