Chondro-Gide Jubilee Chondro-Gide

AMIC® Chondro-Gide® is a minimally invasive 1-step treatment that uses Autologous Matrix-Induced Chondrogenesis (AMIC®) combined with Chondro-Gide® to repair cartilage defects of all sizes. Backed by more than 10 years of clinical success, AMIC® Chondro-Gide® is an effective and cost-effective treatment^1,2,3for repairing damaged knee cartilage, alleviating or preventing pain, and slowing the progression of damage.

AMIC® Chondro-Gide®combines microfracturing (MFx) with the use of Chondro-Gide®, which covers and protects both the super clot resulting from MFx and the repair tissue.⁴ It can be performed either by mini-open or arthroscopic methods. Biocompatible and fully resorbable, Chondro-Gide® supports the body’s own healing potential.

Benefits

With its specially designed bilayer structure, Chondro-Gide® provides a protective environment that fosters the growth of new tissue.^5,6

Bio-derived, bilayer Collagen I/III membrane⁵
Biocompatible and naturally resorbed⁵
Easy to handle: supple and tear-resistant⁵
Can be glued into place⁵
Compatible with a range of tissue regeneration techniques⁷
One-step procedure⁵
Ready for use off the shelf⁵

Mini-Open Surgical Technique, Dr. M. Steinwachs

1. Mini-Open: Prepare the Surgical Site

5. Mini-Open: Remove the Residual Tissue

7. Mini-Open: Position and Glue the Chondro-Gide®

8. Mini-Open: Suturing Instead of Gluing

Using a standard, minimally invasive anterior approach, open the knee joint. Remove damaged and unstable cartilage with a scalpel, curette, and spoon until a stable, perpendicular shoulder surrounds the defect.

Clinical Evidence AMIC® Knee

AMIC® Chondro-Gide® has been shown to be an effective treatment to repair cartilage lesions of all sizes in the knee. Clinical studies show successful treatment using AMIC® Chondro-Gide^®with both mini-open and arthroscopic techniques for more than 10 years.¹⁴

Better Performance than MFx Alone, After 2 Years

In a randomised, controlled 3-arm study of 47 patients in 2 centers¹⁵, a significant deterioration in results was seen after 2 years following MFx alone (without Chondro-Gide®). Pain and function scores (ICRS and modified Cincinnati scores) remained stable or even improved with AMIC®, while pain and function scores for the MFx group decreased.

Functional Status Over Time

AMIC® Shows Better Performance than MFx Alone After 2 Years.

Arthroscopic or Mini-Arthrotomy, both Give Equally Good Results

In a retrospective study, Schagemann et al.¹⁶ compared the clinical outcomes of AMIC® Chondro-Gide^®procedures that were performed as arthroscopic or mini-open surgeries. The study followed patients up to 2 years. According to the patients’ Visual Analog Scale (VAS), Lysholm scores, and Knee injury and Osteoarthrithis Outcome Scores (KOOS), both surgical approaches yielded equally positive results.

First Meta-Analysis of 12 AMIC® Chondro-Gide® Studies Including 375 Patients

Most recently, (2019) in a systematic review and meta-analysis of AMIC® outcomes, the authors evaluated grade III/IV chondral and osteochondral lesions in the knee with a mean defect size of 4.24cm² with up to 7 years follow-up.

The use of AMIC^®Chondro-Gide® in defect sizes, which are above the recommended threshold for MFx, significantly reduced pain and improved function from baseline to follow-up. The meta-analysis documents that the AMIC® Chondro-Gide® procedure significantly improves pain and functional outcomes in knee joints with chondral or osteochondral lesions. The results further demonstrate that the improvement was maintained over more than 5 years, which confirms the long-term success of AMIC^®Chondro-Gide® in larger (>4cm²) grade III and IV lesions.¹⁷

ACI-C and AMIC^®Chondro-Gide® provide equally good results after 2 years

Fossum, et al., (2019) conducted a prospective, randomised, controlled study to assess the outcomes of ACI-C and AMIC® in chondral and osteochondral defects of the distal femur and patella. No significant differences were seen between the outcomes of the ACI-C and AMIC® techniques at 1 and 2 years.

The authors concluded that AMIC® could be considered a clinically equal, but less expensive alternative to ACI-C, as AMIC® is a 1-step procedure therefore far less resource-intensive.¹⁸
