 Alpha Chondro Shield® is produced by Swiss Biomed Ortho and distributed by Hospital Innovations in the UK

 


 

Applications

The cell-free cartilage implant Alpha Chondro Shield® (ACS) is a cell-free cartilage replacement material designed to treat large focal cartilage defects of the knee. ACS relies on the migration and differentiation potential of mesenchymal stem cells (MSCs), which are released from the subchondral bone after the microfracture procedure. These attach to the fibres of the fleece material and form a blood clot, and eventually replace lost hyaline cartilage. This is advantageous over microfracture alone, particularly for larger defects where microfracture has shown increased chances of failure.   Mechanical properties and the PGA in the implant material improves biocompatibility properties over other synthetics.

 


 

Objectives

This project will investigate biological and functional properties of a surgical material called AlphaChondroShield®, and conventional surgical procedure microfracture both in vitro and in humans.

ACS® is an absorbable, cell-free cartilage resurfacing material made from a woven polyglycolic acid fleece.
