Study Comparing Two Methods for the Treatment of Large Chondral and Osteochondral Defects of the Knee

"* A biopsy of healthy cartilage is taken from a non-weight bearing area of the knee joint during an arthroscopic procedure.~* The biopsy is processed in the GMP accredited laboratory to isolate and amplify chondrocytes.~* The cells are seeded and cultured on a collagen matrix (Chondro-Gide®, Geistlich Pharma)~* The membrane is implanted and sutured onto the injured site."

This treatment combines the microfracture procedure with the application of a bilayer matrix of porcine type I/III collagen (Chondro-Gide, Geistlich Pharma) and the supplementation of autologous bone.
