Primary outcomePrimary: Differences in Decision Conflict Scale With ASK vs Usual Care — 25.1; 26.0 Score on a scale
Summary
Knee and hip osteoarthritis (OA) is the most common cause of disability in the U.S. and affects more than 60% of adults over 65 years. As the burden of knee and hip OA increases among aging adults, more patients are deciding to have joint replacement surgery. However, no clear guidelines exist for patients to determine if or when to undergo total joint replacement (TJR).
The investigators plan to develop a web-based system that will provide individualized patient OA Care Plans that will help patients make informed decisions about how to treat their arthritis. The investigators will be using this system with patients to see if they find it useful.
The investigators believe that the OA Care plan will improve the process and quality of OA treatment decisions and the quality of OA care.

Eligibility Criteria
Inclusion Criteria
- All new patients to participating surgeon's practice for the purpose of evaluation of knee or hip OA are possible participants.
- Patients must be 40 years of age or older and able to provide informed consent.
Exclusion Criteria
- Inflammatory arthritis, such as rheumatoid or psoriatic arthritis
- Recent knee or hip injury as purpose for visit
- Pregnant women
- Prisoners
- Non-English speaking subjects- As we are refining and testing a web-based system intervention that provides individualized patient OA Care plans to improved shared decision making between patients and providers, for research purposes we must assure that the 'counseling' between the surgeon and patient will be in their native language. Once we have identified what materials work at the end of the study, we will translate materials into Spanish.
