Surgical Joint Registry MBJRF

This is a registry database. Consented subjects will have their medical data collected via a
patient questionnaire in either paper or web based application form. Data will be collected
prospectively and retrospectively and will be entered into the database generated by Memorial
Bone and Joint Research Foundation. Collection of data will start during the initial clinic
visit as part of standard of care. Subjects will be asked to fill out a 4-page "pre-operative
hip questionnaire" or "pre-operative knee questionnaire", which includes questions for
self-assessment from the Hip Disability and Osteoarthritis Outcome Score (HOOS), Knee
disability and Osteoarthritis Outcome Score (KOOS), EQ-5D and University of California, Los
Angeles Activity (UCLA) questionnaires. Demographic, intra-operative and additional data will
also be collected to correctly identify the subject's specific disease process and treatment
plan. Subjects will be asked to fill out a post-operative hip and knee questionnaire that is
similar to the pre-operative questionnaire to evaluate the improvement in their clinical
outcomes. The subjects will be requested to complete the post-operative questionnaires at 6
months and annually thereafter.
