- INTRODUCTION: Decision boards can be useful in shared decision making by helping patients and their physicians choose among treatment options. Two surgical treatments for early knee osteoarthritis (OA) are high tibial osteotomy (HTO) and the KineSpring® Knee Implant System. The primary objective of this study was to determine patient preferences between these two treatments using a decision board. METHODS: We developed a decision board that presented information on HTO and the KineSpring System for treating knee OA. First, it was presented to 15 individuals for a pilot test and a "scope test." Then it was presented to 81 individuals who were asked to imagine that they had early to midstage knee OA, and this group was administered a complete a series of questions, including their treatment preference and what they would be willing to pay if they elected to use the KineSpring System. Descriptive statistics were calculated and a chi-squared test was conducted to assess any significant differences in patient preferences based on demographic characteristics. RESULTS: Our pilot test confirmed that most participants (87%) agreed that the decision board was easy to understand and helped them in making a decision. Of 81 respondents, the KineSpring System was preferred by 60% (n = 49). Individuals selecting KineSpring would be willing to pay an average of $2,700 to receive it over HTO. CONCLUSIONS: When provided with treatment options and information, 60% of individuals preferred the KineSpring System over HTO. The decision board was well-received as a useful tool for presenting information.
