title: Patients' perspective on controversial issues in total knee arthroplasty.
abstract: We investigated the level of patient knowledge and preferences over the currently controversial issues in TKA. One hundred patients who had decided to undergo TKA for advanced osteoarthritis were asked to complete a questionnaire inquiring their knowledge and preferences over three controversial issues: (1) computer assisted surgery (CAS), (2) minimal invasive surgery (MIS), and (3) ceramic femoral component. The patient preferences over the three issues were questioned again after they had been informed of advantages and disadvantages of each option using an explanatory document. Most (more than 75%) of the patients did not have sufficient knowledge and their knowledge was based on non-professional sources (more than 85%). Before the information was given, most (more than 80%) of the patients preferred a new option. After the information was provided, more patients preferred a standard option in the issues of CAS (60%) and MIS (88%). This study prompts health care providers to become more active in providing accurate information and to consider patients perspective in making decisions which will influence the benefits and risk of the patients.
