AMIC® Chondro-Gide®

AMIC® Chondro-Gide® is a minimally-invasive 1-step procedure that can be performed either by mini-open surgery, or in an arthroscopic manner. Developed by Geistlich Surgery in collaboration with leading surgeons in Europe, this technique has been effective in repairing chondral or osteochondral defects in the knee, talus,  and hip.1,2,3 

The Benefits of Using AMIC® Chondro-Gide®

With both mini-open and arthroscopic techniques, the unique advantage of AMIC® Chondro-Gide® is that it supports the body’s own potential to heal itself. Damaged cartilage is removed, and then bone marrow stimulation (BMS) techniques are used to bring regeneration supporting cells to the defect site.

The membrane covers the defect and serves as a protective shield that contains the cells and minimizes the impact of shear forces on the delicate superclot. At the same time, it functions as the roof of a biological chamber that forms over the defect.  The biocompatible collagen material provides an environment for cell growth and is replaced by new cartilage tissue over time.4


Developed to Support Regeneration: AMIC® Chondro-Gide® 

Building on the established AMIC® technique, which already includes stimulation of regenerative processes by BMS, various approaches exist to extend the range of biologic factors used in the treatment of cartilage defects. The palette of biologic factors that have been used to date includes, for example, platelet rich plasma (PRP) 6,7,8, bone marrow aspirate/concentrate (BMA/C)9,10,11, minced cartilage (MC)12, and autologous microfragmented adipose tissue13. They have been used in various combinations with AMIC® .

Whether these additional biological components can be used depends on regulatory guidelines in each country.

While the biological components and combinations of factors vary in the new AMIC®+ approaches, all techniques rely on Chondro-Gide® to keep cells in place and create a biological chamber which protects the regenerate and supports the body’s healing potential. Future studies will show whether the addition of one or multiple biological components can improve cartilage repair in comparison to the established AMIC®approach.
