AI Technical Summary

Technical Problem

Existing gap assessment in total knee arthroplasty relies heavily on qualitative, intuition-based methods, lacking standardized tools to quantify forces and torques applied during abduction-adduction examinations, which can lead to inconsistent surgical decisions and suboptimal prosthetic component selection.

Method used

A system and method utilizing force sensors placed at specific ankle and foot positions to measure applied forces, coupled with a computing device to calculate peak forces, determine medial and lateral gaps, and provide real-time feedback for consistent surgical procedures.

Benefits of technology

Enables accurate quantification of forces and torques, standardizing gap assessment to improve prosthetic component selection and surgical outcomes by providing real-time recommendations and reducing variability among surgeons.
