Wireless technologies are incorporated in implantable devices since at least the 1950s. With remote data collection and control of implantable devices, these wireless technologies help researchers and clinicians to better understand diseases and to improve medical treatments. Today, wireless technologies are still more commonly used for research, with limited applications in a number of clinical implantable devices.

- Mechanical loads during activities like walking are key to bone repair, but measuring these forces internally in the body is challenging, hindering effective recovery strategies.
- Researchers created an implantable strain sensor to measure these forces in real-time while bones heal, revealing that a load-sharing fixator greatly boosts healing outcomes.
- The study highlights that early mechanical cues significantly influence long-term bone regeneration, suggesting that non-invasive strain sensing could serve as a safer alternative to traditional imaging for assessing bone healing.
Clinical potential of implantable wireless sensors for orthopedic treatments.

Introduction: Implantable wireless sensors have been used for real-time monitoring of chemicals and physical conditions of bones, tendons and muscles to diagnose and study orthopedic diseases and injuries. Due to the importance of these sensors in orthopedic care, a critical review, which not only analyzes the underlying technologies but also their clinical implementations and challenges, will provide a landscape view on their current state and their future clinical role.
Areas Covered: By conducting an extensive literature search and following the leaders of orthopedic implantable wireless sensors, this review covers the battery-powered and battery-free wireless implantable sensor technologies, and describes their implementation for hips, knees, spine, and shoulder stress/strain monitoring.
