Medical-grade polycarbonate assists with knee replacements

Polycarbonate strikes the right balance for knee replacements

Makrolon® polycarbonate helps surgeon optimize implant placement

Previously, surgeons had to subjectively determine the amount of pressure to apply to a knee implant during surgery. Now, a device provides real-time data to the surgeon to make adjustments.

Ortho Sensor
Makrolon® Rx1851 polycarbonate from Covestro provided the necessary biocompatibility and superior strength for the OrthoSensor™ Knee Balancer.

Task

The OrthoSensor™ Knee Balancer is a revolutionary, intelligent orthopedic device that uses sensors and wireless technology to provide evidenced-based data for surgeons to optimize the positioning and balance of implants. Using a high-quality material in the manufacture of the device was paramount.

Challenge

The device is available in four transparent colors, each indicating a specific surgical size. OrthoSensor had several criteria for choosing a material for the innovative OrthoSensor™ Knee Balancer, including biocompatibility, superior strength and technical support from the supplying company.

Solution

Makrolon® Rx1851 polycarbonate from Covestro checked all the boxes. Not only does this medical grade of resin offer improved flow, lubricity, easy release and strength, it’s also compliant with FDA-modified 10993, Part 1. Critical to the project was Covestro’s ability to provide custom color formulations for its biocompatible grades of Makrolon®. During development, Covestro worked with the molder to safeguard the integrity of the material and assure that OrthoSensor’s high standards were met.
