Robotic Assisted Tensioner - 2023

CORI Robotic Knee Tensioner

Advancing procedural innovation in robotic-assisted surgery, the CORI Digital Tensioner is a differentiated technology that helps solve challenges for surgeons

The CORI Digital Tensioner produces a surgeon-defined, quantifiable force to distract the knee joint, apply consistent tension to the ligaments, and provide objective gap data for procedure planning and execution. A small clinical case series showed the CORI Digital Tensioner reduced variability of tensioning by 64% when compared to a manual technique.


I worked as the Industrial Design Lead for the CORI Robotic Knee Tensioner as part of Smith + Nephew's Human Factors + Design Team. The goal with this device was to provide fast and accurate gap data for procedure planning, with a heavy focus on ergonomics. The form needed to be small, but easy to grip and maneuver while flexing the knee to collect gap data. Final renderings I created are also being used across Smith + Nephew's marketing materials for this device.


The first and only ligament tensioning device in robotic-assisted surgery to assess joint laxity in the native knee before performing bony resection. Automatic collection of gap data at a specified force through the full range of movement.

A true tensioning device using a software interface that allows surgeons to choose their preferred target force value (50±10N, 100±10N, or 150±10N)
