Joint arthroplasty within 10 years after primary charnley total hip arthroplasty.

To evaluate the need for joint arthroplasty within 10 years after index primary Charnley total hip arthroplasty (THA) performed for osteoarthritis, we retrospectively reviewed the cases of 2,547 patients, 50 to 75 years old, from 1969 to 1984, with a minimum potential 20-year follow-up. In this article, we report the age, sex, and time data from this study. For the entire patient population, the 10-year rate of undergoing contralateral THA was 35.0%; ipsilateral hip revision, 6.2%; ipsilateral total knee arthroplasty (TKA), 0.6%; contralateral TKA, 1.9%; and bilateral TKA, 0.2%. The 10-year death rate was 21.8%. With more than 200,000 THAs being performed in the United States each year, these numbers can guide orthopedic surgeons in their discussions about subsequent arthroplasty procedures on other joints.
