Digital Knee®
The Digital Knee® is an advanced remote goniometer and software platform that seamlessly integrates with wearables to provide accurate, real-time RPM and RTM monitoring and clinical insights for orthopedic care.
What the Digital Knee® does
The Digital Knee® is a continuous remote goniometer that seamlessly “clips on” to wearables - therapeutic braces for post-surgery, offloading for knee OA, soft sleeves or used as a standalone goniometer when bracing is not needed such as post-knee replacement.
The sensor is accurate to less than 1 degree, requires no calibration and is intuitive for a patient at home. The extendable goniometer arm design and strategic sensor location, anatomically aligned on the affected limb, ensures the measurements are less susceptible than patch sensors to “noisy data” and errors due to skin movements, especially in patients with excess soft tissue. Unlike patch sensors, the Digital Knee® does not use skin adhesive, which can cause irritation and infection for sensitive skin.
The accuracy, reliability and usability of the Digital Knee® assessments have been validated in peer-reviewed papers. For example, ACL patients used the device for six weeks post-surgery with maximum group knee flexion of 1°, different from an in-clinic goniometer and remote Digital Knee® assessment. Compliance with the Digital Knee® assessment over 6 weeks was also high at 79%.
An iOS and Android patient-facing app provides patient engagement, insights and education. Our research has shown your patients will benefit from a more connected care experience, resulting in better motivation, engagement and program adherence.

Digital Knee® Lab & Provider Portal
The Digital Knee® Lab is the brains of the solution, processing data from the sensor to provide insights to a patient’s mobile app and clinical teams via a web portal.
The Digital Knee® portal makes every aspect of implementing remote patient monitoring (RPM) and Remote Therapeutic Monitoring (RTM) effortless. Proprietary algorithms and notifications tell you how patients are progressing and help you perform assessments that can assist in informing clinical decisions. All providers in the continuum of care are empowered to collaborate to support each patient.
Opum’s flexible protocols allow clinicians to easily design and prescribe personalized care that includes monitoring therapy and bracing and patient progress towards their goals. Opum’s self-service portal outputs printable patient-friendly clinical data reports to help facilitate discussion on progress and treatment options
Manage patients across your practice with RPM and RTM to track how well you perform regarding outcomes and efficiency. Utilize data to support value-based care initiatives.
Case Study:
RCT Validating the Impact of the Digital Knee® for Osteoarthritis Patients
Study Purpose: To investigate the impact of Opum’s Digital Knee® intervention in individuals with knee osteoarthritis.
Study Site: Shirley Ryan Ability Lab Chicago (#1 ranked US rehab hospital)
Design: 60 participants, 12-week randomized control trial, registration number: NCT05222503.
Summary Results:
Adding the Digital Knee® to a conventional knee brace intervention increased patient retention by >20%
Digital Knee® saw clinically significant improvement in all 5 of the KOOS survey sub-scores compared with only 2 for the control.
Aerobic capacity and endurance in the 6-minute walk test significantly improved in the Digital Knee® group but not in the control.
Walking speed improvement was greater in the Digital Knee® group for comfortable and fast paces.
Strength, balance and fall risk assessed using 5x sit-to-stand improved significantly in the Digital Knee® group.
Weight loss in the Digital Knee® group was more than three times that of the control group.
