Summary
Most total knee replacement patients lack knowledge on surgical options like computer-assisted surgery and minimally invasive techniques. Providing clear information shifts preferences toward standard approaches, highlighting the need for better patient education.
Area of Science:
- Orthopedic Surgery
- Patient Education
- Medical Decision-Making
Background:
- Total knee arthroplasty (TKA) involves complex decisions regarding surgical techniques.
- Patient understanding of controversial TKA issues like computer-assisted surgery (CAS), minimally invasive surgery (MIS), and ceramic femoral components is often limited.
- Existing patient knowledge frequently stems from non-professional sources.
Purpose of the Study:
- To assess patient knowledge and preferences regarding controversial TKA issues before and after receiving informational counseling.
- To evaluate the impact of providing detailed information on patient choices for CAS, MIS, and ceramic femoral components.
- To emphasize the importance of patient-centered communication in TKA decision-making.
Main Methods:
- A questionnaire was administered to 100 patients scheduled for TKA due to advanced osteoarthritis.
- Patients' knowledge and preferences on CAS, MIS, and ceramic femoral components were assessed.
- Preferences were re-evaluated after patients received an explanatory document detailing the pros and cons of each option.
Main Results:
- Over 75% of patients demonstrated insufficient knowledge, with over 85% relying on non-professional sources.
- Prior to information, over 80% favored novel options.
- Post-information, preferences shifted significantly towards standard options for CAS (60%) and MIS (88%).
Conclusions:
- Healthcare providers must actively disseminate accurate information to TKA patients.
- Patient perspectives and informed decision-making are crucial for optimizing TKA outcomes.
- Educational interventions can significantly influence patient preferences in TKA surgical choices.
