The Effect of Socioeconomic and Psychosocial Factors on Patient Perceived Outcome of Total Joint Arthroplasty
Patients will qualify for the study once they have been determined to be a candidate for a total joint replacement of either the hip or knee by one of the primary investigators. If they agree to participate in the study, they will be asked to fill out a demographics questionnaire that will include their name, address, phone number, disease process, type of joint replacement, complications, and income level. They will also be asked to fill out a variety of validated outcome surveys and health status questionnaires. Subjects will be required to fill out these surveys preoperatively and at 6 and 12 months, postoperatively (which are the standard follow- up intervals in our clinic, whether a patient participates in a study of not). Some surveys require clinical information that will be obtained by a physician. Surveys to be used include the following: Short Form – 36; Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index; the Patient Data Questionnaire; the Patient Health Questionnaire; the Harris Hip Score and/or the Knee Society Score; Treatment Helpfulness Questionnaire; and a demographics questionnaire. The subjects will be assigned a PIN number and all of their data will be kept confidential.
Subjects between the ages of 18-90 years, with old osteoarthritis, osteonecrosis or post traumatic arthritis of the hip or knee, who are determined by the primary investigators to be candidates for a primary total joint arthroplasty will qualify for the study. There will be no restrictions on income, gender, previous therapy, race, or ethnicity. There will be no restrictions in regard to life expectancy, co-morbidities, or nutritional status, unless these criteria, by themselves, determine the patient to be a non-arthroplasty candidate.
