“…Arthroplasty remains invasive and is proposed after declining quality of life, long periods of chronic pain (Sjoling et al, 2005), and severe limitations: social isolation; feelings of belittlement; feelings of burdening others or of vulnerability; dependency; negative mood; and fatigue (Toye et al, 2006). Arthroplasty is proposed when the intensity of pain becomes unbearable (Fortin et al, 1999;Jolles and Leyvraz, 2006;Zambelli and Jolles, 2006), and when other treatments (medication, physiotherapy or surgical solutions) become ineffective (Hawker et al, 2001;Hill and Davis, 2000).…”
