Figure 2. A. Incidence of all hip arthroplasties for primary osteoarthritis in young patients (30–59 years of age), by sex. The increase in incidence during 1980–2007 was greater in men than in women (p < 0.001). B. Incidence of total hip arthroplasty (THA) for primary osteoarthritis in young patients (30–59 years of age), by sex. C. Incidence of resurfacing hip arthroplasty (RHA) for primary osteoarthritis in young patients (30–59 years of age), by sex. The increase in incidence during 2001–2007 was greater in men than in women (p < 0.001).
