BoneChat #131 - Lessons learned building wearables for orthopedics

In this episode of BoneChat, we are joined by MedTech entrepreneur Lisa Voronkova (CEO of OVA Solutions) to discuss the rapid evolution and future of remote monitoring and wearable electronics in orthopedics. Key Topics Covered: The Clinical Shift to the Home: Why the most critical phase of patient recovery happens outside the clinic, and how wearables bridge the data gap during the 167 hours a week a patient is at home [03:48]. The Evolution of Form Factors: The shifting landscape of wearable tech—moving away from traditional smart rings and watches toward localized, intelligent skin patches and smart implants [05:16]. Market Mapping: Understanding the distinction between "diagnose/screen" tools (consumer-facing fitness wearables) and "treat/control" tools, which deliver high-value clinical data directly tied to surgical rehabilitation [07:20]. Practical Medical Applications: Monitoring localized temperature to catch post-op infection and inflammation days before a clinical visit [11:29]. Utilizing EMG (electromyography) sleeves and pressure-sensing insoles to track real-world muscle activation, symmetry, and rehabilitation progress [13:41]. The Frontier of Smart Implants: A look into FDA-cleared technology like the Persona IQ smart knee implant, which utilizes internal accelerometers and gyroscopes to track raw joint metrics directly from the bone for up to 10 years [17:05]. The Real Engineering Challenges: Breaking down the six factors that make or break a medical wearable, highlighting why adding a sensor is the easy part, while processing clean signals, managing device power, and achieving data-out are the real hurdles [20:51]. Self-Powering Innovations: How new piezo-electric and triboelectric harvesting technologies are capturing power from raw walking loads to create self-sustaining orthopedic sensors [23:27].
