title: Total joint arthroplasty in patients with rheumatoid arthritis: a United States experience from 1992 through 2005.
abstract: To determine whether total joint arthroplasty (TJA) for patients with rheumatoid arthritis (RA) is decreasing, we collected Nationwide Inpatient Sample database information (1992 through 2005) on (1) the number of primary TJAs for all patient diagnoses, (2) the number of primary TJAs for patients with RA, and (3) distribution of age and sex in both groups. To account for population growth, a given year's arthroplasty estimate was normalized against its population. The trends over time were analyzed using a multivariable Poisson regression model (significance, P < .05). We found that the number of primary TJA procedures increased in the general and RA populations but that, after adjusting for population growth, age, and sex, the rate was significantly lower in patients with RA.
