(A): What inspired you to begin developing wearable technologies for users with knee impairments?
(J): “We started with knees mainly because of my co-founder, Herbie Kirn’s, own personal needs. He lost his right leg in a motorcycle accident over fifteen years ago and quickly wore down the cartilage in the knee of the fully intact leg as he relearned to walk. He was told he was too young for knee replacement, but he was advised to go through all of the conservative options available and found braces, injections, and medications each to have unacceptable drawbacks or side effects. What did work for him was physical therapy (PT), with an emphasis on quadriceps strengthening, but he didn’t have time for all of the rehab he needed without impacting his work and family responsibilities. While at PT, he was using a neuromuscular electrical stimulation unit while doing leg lifts and started wondering why this process wasn’t more fully automated.
We discovered that Herbie wasn’t the only one lacking PT access, nor were his positive results from strengthening all that unique. Poor quadriceps muscle strength correlates with pain, poor mobility, and a lower quality of life, creating $3B in avoidable healthcare spending. Physical therapy is effective, but we see that <20% of patients attend all prescribed sessions or remain compliant with their home-based regimens. The need exists to bring physical therapy to the patient when the patient can’t come to physical therapy.”
(A): Can you tell us a bit about your competitors and how you plan to maintain your lead?
(J): “Short-term, our main competitors will be in the knee brace manufacturing market ($0.5B) and the electrical stimulation devices ($4.7B). Companies like DJO (now Enovis) and Ossur are in both and, to us, represent ideal partners rather than adversaries. Longer-term, we’ll run into more challenges with full remote/virtual physical therapy platforms like Hinge and Sword Health that can offer one device/setup to address all joints, not just one. In all cases, we believe our response has to be to prove that we offer higher quality rehab outcomes and greater convenience for end-users.”
(A): How do you keep yourself updated? Is there anything specific you refer to?
(J): “For where we are in the medical device, orthopedics, and physical therapy spaces, I get a lot of value from following Osteoarthritis Action Alliance, Rock Health, Fitt Ventures, Orthoworld, and SportsTechie Daily. Specific to Texas and looking for local opportunities and trends, I’d point to Dallas Innovates, Texas Squared, AustinInno, and CultureMap Houston. Completely outside of those spaces, I’ve found a lot of solid self-improvement content, especially around maintaining focus and self-awareness, with Nir Eyal’s work, and I enjoy the Sunday Long Read compilation of long-form journalism compiled by Don Van Natta.”
