A Multi-centre Study of Shoe-worn Insoles and Knee Osteoarthritis

Participants will be asked to wear these insoles in their own shoes for at least 5 hours per day for a period of 3 months. The LWIs will be constructed via 3D printing using a material of uniform density made to the length of the participant's feet, and will incorporate a 6 degree wedge along the lateral edge.

Participants will be asked to wear these insoles in their own shoes for at least 5 hours per day for a period of 3 months. These insoles will be designed based on an innovative tablet-based app designed by industry partner Kintec Footlabs, who will be the provider of the insoles for this project. Using the high-fidelity 3D scanning tool available (Apple's True Depth sensor), the Epitek Self-Scanner app captures tens of thousands of 3D data points within a single 1-second capture, and then uploads this foot data to a secure patient record system that is used for insole fabrication. The LWAS insoles will be comprised of variable density material (more dense laterally than medially) and milled directly to produce a full-length shell. The 6 degree wedge will be incorporated along the full lateral length of the insoles.
