This study is a follow-up durability trial from the CAMPX randomized controlled clinical trial. Only subjects who achieved complete closure at 12 weeks in the CAMPX trial will be evaluated. After signing the IRB-approved informed consent form, the subject will receive instruction on the BlueDrop® OneStep Foot Scanner™. In addition, written instructions on use will be provided. Subjects that are unable to use the scale will be asked to answer a questionnaire at 3, 6, 9, and 12 months after signing the consent form.

Subjects with eligible wound will receive a BlueDrop® OneStep Foot Scanner™. They are instructed to step on the scale each morning. The Bluetooth technology transmits a photograph and thermal image to the central monitoring nurse at BlueDrop®. All information transmitted is compliant with HIPPA regulations. Subjects that are unable to use the scale will receive a phone call at months 3,6, 9 and 12 months to determine if the foot has remained closed.

To demonstrate durability of closure (rate of recurrence) of subjects with a closed diabetic foot ulcer during the CAMPX clinical trial comparing subjects treated with Single Layer Amniotic Membrane (SLAM) plus standard of care (SOC) to subjects treated with SOC alone.

To evaluate the effectiveness of virtual clinical trial technology in the conduct of a long-term follow up trial.
