MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641020788 A) filed by Saveetha Institute Of Medical And Technical Sciences, Chennai, Tamil Nadu, on Feb. 23, for 'adaptive tibiofemoral load-shift footplate for knee joint load management.'
Inventor(s) include Jayashree J; Dr. K. Kottee Swaran; and Deepak Nallaswamy Veeraiyan.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a plantar-based adaptive orthotic system for dynamic modulation of tibiofemoral joint loading during gait. Knee osteoarthritis and varus/valgus malalignment commonly result in excessive compartmental loading, accelerating cartilage degeneration and functional impairment. Conventional interventions, including knee braces and static wedge insoles, provide fixed correction, lack real-time adaptability, and may compromise patient compliance. The Adaptive Tibiofemoral Load-Shift Footplate (ATL-F) integrates plantar pressure sensors, a microcontroller-based control unit, and an internally adjustable micro-tilting wedge mechanism within a footwear-compatible footplate. The system continuously monitors plantar pressure patterns and selectively adjusts wedge orientation during the stance phase, thereby redirecting ground reaction force vectors and reducing medial or lateral knee joint loading without constraining knee motion. By providing stepwise, dynamic load correction, the ATL-F offers a non-invasive, brace-ffee, and functionally integrated solution for conservative management, gait rehabilitation, and prevention of osteoarthritis progression valg."
