Due to osteoarthritis pain will increase over time, to the point the disease will influence the quality of the daily life of people. A total hip arthroplasty (THA) will be the solution to relieve the patient of the damaged hip. Among 33.497 patients had a THA surgery in 2008 and 2.185 patients a revision in the Netherlands. It is expected the demand for a hip replacement will triple by 2030. The literature study revealed that the in-hospital stay has decreased to 1.85 nights, with the ultimate goals of single-day discharge after THA surgery. To continue this trend, rehabilitation is the next step in improving the patient’s experience of THA surgery. The main bottleneck of the rehabilitation phase is the exercise program and regime. After surgery the patients will be referred to a local physical therapist, in which case the patient will continue being a patient. This is in conflict with the approach of rapid recovery where the patients will directly be supported in trusting their new hip, and by using it as normal. Staying a patient can have a negative effect on the rehabilitation phase, so by removing the local physical therapist from the process this patient will not be a patient anymore. By replacing this with a new solution the patients will all receive the same new treatment, and more or less result in the same outcome. This outcome can vary due to difference in personality. Therefor patient types are a good solution to give a tailored approach to different patients. The explorative research explored the patient’s experience, information about rehabilitation and the exercise program. To explore these topics, three researches have been performed; a questionnaire among THA patients, observations at a rehabilitation centre, and interviews with medical specialists. Combining the conclusions of the literature study and the explorative research resulted in five main insights about the future of rehabilitation. 1. A future of rehabilitation without exercise program or restrictions shows great possibility; 2. A void created by an intensive pre-op period should be filled; 3. A new kind of recovery should involve being active, healthy, and resume or renew daily life; 4. Increase medical certainty during rehabilitation; 5. The focus of rehabilitation should be on creating a healthy gait. These five insights provide the basis for three different design directions. Two design directions have been combined to continue this project. The starting point for the ideation phase is the following design vision: ‘Design a solution that supports the patient to create a healthy gait during daily life, and trigger them with feedback to keep conscious of their body and gait. The design should provide the patient with a feeling of medical certainty while giving information, inspiration and feedback.’ After the formulation of the vision, and a list of requirements and wishes, the ideation phase started. The ideation phase started with a research into gait analysis techniques and professionalism without involving a professional. With the gathered knowledge several brainstorms were performed, and clustered into three idea concepts. These ideas were elaborated into three feasible concepts, which mainly differed in the means of use, gait analysis technology, and value. Out of these three concepts, the BioStep concept was chosen to optimize into a final design, prototype and business plan. BioStep provides the user with a new kind of rehabilitation. It provides the user with the freedom to restart daily life directly after their THA surgery without feeling like a patient, because with their new hip prosthesis they are not restricted due to the arthritis anymore. Their daily life and activities become their rehabilitation program together with BioStep. The core elements of the BioStep are: - Creating a healthy gait by tracking the gait, creating awareness, and solutions for abnormalities in the gait; - Create a new way of rehabilitation intertwined in daily life; - Patient empowerment by creating their own rehabilitation path, to motivate, remember and encourage them why they should be active; - Expand motivation and comfort zone by inspiring with new activities, and connecting peers to share information, and experience. After finalizing the final design, a prototype was built to verify the technology and value of the design. To achieve these goals two prototypes, tangible prototype of BioStep and application, were reviewed in two evaluation studies. The first evaluation study verified that the technology shows great probability for the future. The second evaluation study shows a positive reaction of the participants and the added value of the product. Bottlenecks derived from the evaluation study are described, and modified in the final design. The business plan for BioStep was elaborated during the last phase of the design process. The business model canvas is a visual tool to communicate the business in a transparent and organised way. The customers are THA patients and has the potential to grow to 335.682 patients in the Netherlands per year. With a realistic view, an estimation of 10 percent was made, and shows a market of 33.000 possible buyers. The following cost estimation, value of BioStep, introduction plan, and future plan have been established on the basis of the business model. In the final phase of this graduation project the conclusions were drawn in relation to the design vision, and the list of requirements and wishes. Lastly, recommendations will be suggested for the future development of the BioStep by Biomet.
