A cross-sectional, community-based survey of a random sample of 1750 of 242,311 Medicare recipients was performed.
The patients were at least sixty-five years old and had had a primary or revision knee replacement (either unilaterally or bilaterally) between 1985 and 1989.

Each sample was stratified by race, age, residence (urban or rural), and the year of the procedure.
Valid and reliable questionnaires were used to elicit the participants'assessments of pain, physical function, and satisfaction two to seven years after the knee replacement.
Of the 1486 patients who were eligible for inclusion in the survey, 1193 (80.3 per cent) responded.
The mean age of the respondents was 72.6 years.
Eight hundred and forty-nine respondents (71.2 per cent) were white, and 849 (71.2 per cent) were women.
