One Bilayer Collagen Membrane for Cartilage and Meniscus Repair

Geistlich Chondro-Gide® is a resorbable bilayer membrane made from highly purified porcine collagen types I and III. It provides a protected biological environment that supports cell attachment and tissue regeneration.

Phoenix offers Chondro-Gide® for both AMIC® cartilage repair and AMMR® meniscus preservation.

Bilayer Membrane Design

The membrane has two functionally different surfaces:

• Rough, porous surface: Faces the cartilage defect or meniscal tissue and supports cell attachment and tissue ingrowth.
• Smooth, compact surface: Faces the joint cavity and helps retain cells within the treatment area while protecting the repair environment.

AMIC® – Cartilage Repair

AMIC®, or Autologous Matrix-Induced Chondrogenesis, is a single-stage cartilage-repair procedure combining bone-marrow stimulation with Chondro-Gide®.

After the damaged cartilage is removed, microfracture or another marrow-stimulation technique releases regenerative cells into the defect. Chondro-Gide® covers and stabilises the resulting superclot, helping protect it from displacement and shear forces during the early healing phase.

AMIC® Applications

• Chondral and osteochondral defects of the knee
• Osteochondral lesions of the talus
• Focal cartilage defects of the hip
• Cartilage defects of the first metatarsophalangeal joint (MTP joint)
• Arthroscopic, mini-open or open procedures

AMMR® – Meniscus Preservation

AMMR®, or Arthroscopic Matrix-Based Meniscus Repair, is designed to biologically augment meniscal repair in tears with limited healing potential.

The meniscus is first stabilised using sutures. Chondro-Gide® is then wrapped around the repaired area, with the porous surface facing the meniscus and the smooth surface facing the joint cavity. Bone-marrow aspirate may be introduced between the membrane and meniscus to create a protected biological chamber around the repair.

AMMR® augments biological healing but does not replace stable mechanical meniscal fixation.

AMMR® Applications

• Complex but repairable meniscal tears
• Tears extending into poorly vascularised zones
• Revision or biologically challenging meniscal repairs
• Isolated meniscal repair
• Meniscal repair combined with ACL reconstruction

Product Features

• Porcine collagen types I and III
• Resorbable bilayer membrane
• Supports cell attachment and tissue formation
• Flexible and easily trimmed to match the defect
• Suitable for arthroscopic and open application
• Available in 20 × 30 mm, 30 × 40 mm and 40 × 50 mm

Clinical results depend on patient selection, lesion characteristics, stable fixation, surgical technique and postoperative rehabilitation.
