The vast majority of the 1 million above-knee amputees living in low- and middle-income countries who need prosthetics each year do not have access to the devices they need to live more healthy, productive lives.
By designing a low-cost, high-quality prosthetic knee that can be delivered through an economically self-sustaining distribution model, D-Rev aims to increase the availability and accessibility of quality prosthetics in underserved regions, and improve the health of amputees as a result.
To measure our progress in reaching amputees who need access to quality prosthetics, we track three main indicators:
- Number of amputees fit
- Number of amputees fit who otherwise would not have been fit with a comparable knee
- Countries where ReMotion Knees have been sold
During our clinical field trials, we also track the following:
- Percentage of amputees fit who continue to wear their knee for a significant period of time after fitting (“Compliance Rate”)
- Percentage of amputees who report experiencing no mechanical failures of their knee (“Non-failure Rate”)
- Percentage of amputees fit who report being satisfied with their knee (“Satisfaction Rate”)
For a detailed description of the assumptions and calculations we use to measure impact, check out our step-by-step explanation.
Goal: Empower amputees through provision of low-cost, high-quality prosthetics
Project started: 2008
First prototype (JaipurKnee) launched: 2008
ReMotion Knee field trials: 2011-14
ReMotion Knee launch: 2015
ReMotion Knee re-launch: 2017 (expected)
Current status: ReMotion Knee officially launched in late 2015. During 2016, sales were paused for additional fine-tuning of device. Sales are expected to resume in mid-2017.
