About the Client

The client has over 20 years of orthopedic design and manufacturing experience, providing proven and reliable total joint implants and instruments to the global market. Located in northern California, the client specializes in high quality manufacturing of hip and knee implants, with a reputation for performance and reliability. Their focus also remains on patient care and clinician relationship.

Business Challenge

Tracking patient rehabilitation post knee-joint-replacement-surgery was a manual exercise, with no real time alternative to help patients & doctors to know their program details, exercise plans, weekly rehab progress reports, pain scores etc. This also hindered useful data & analytics that could be collected, related to postoperative range of motion and rehabilitation.

The client approached Silicus to design and develop a mobile application for patients (PAT App) & doctors (HP App) to track and access real-time data related to kinematics of the knee or hip. The application would push this data to a server side database residing on the Cloud, and sends back analysis to the applications for the patients and doctors to use.

The application back end was developed on the Microsoft.NET platform, while the front end was made accessible from a smartphone, with options for Apple and Android devices. Silicus .NET and Mobile Experts developed a web service that tracks and pushes kinematics data gathered from the wearable implants via Bluetooth from the implant to the Mobile app, and there on using Wi-Fi or any internet access medium to push the data to an MS Azure Cloud database.

The web service gathers information such as the Range of motions (ROM), body temperature, number of steps, extreme changes in acceleration, and pain scores, pushing this data to an Azure Cloud storage. Another module analyses the data in the Cloud and pushes the results into the mobile apps, enabling patients to view real–time biofeedback. The patient application also allowed patients to upload a photo of their wounds, and request physician help on a real-time basis.

The back-end web application (called the Healthcare Professional Web Interface or HPWI) was developed in .NET and C#, connecting the front-end application to the Cloud database, & pushing the data on the web dashboard and vice versa.

The web application also had a UI, allowing administrators to perform the following functions:

  • Patient Management (Add, update, view profile details, reset password etc.)
  • Provider Management (Add, update, view profile details, reset password etc.)
  • Internal Users (Technical Support, Admin)
  • Settings (setting weekly rehab plans)
  • Reminders (patient recovery status, pain score etc)

Silicus leveraged the Azure Cloud environment to deploy the web interface, to connect the patient and provider apps. SQL Azure Cloud services was used to store data.
