the procedures performed to treat osteonecrosis of the hip were THA, which increased to 88% (n = 5632) in 2008. The percentage of joint-preserving procedures consequently decreased from 25% to 12% over this period.
CONCLUSIONS: Previously, THA was believed to have poor survivorship and clinical results for the treatment of osteonecrosis of the hip, but reports since 1993 have suggested improved survivorship of these reconstructions. Our study suggests that surgeons have incorporated this into their practice patterns, in that an increasing percentage of patients with this diagnosis are treated with THA. Additionally, the total number of procedures performed for osteonecrosis has increased, which may reflect an improved awareness of this disease and more aggressive approaches to diagnosis and treatment.
LEVEL OF EVIDENCE: Level III, therapeutic study. See Instructions for Authors for a complete description of levels of evidence.
