Chondrocyte suspension in fibrin glue.
Autologous chondrocyte implantation has been shown to be a promising method for treatment of deep articular cartilage defects. The hyaline cartilage formed by implanted autologous chondrocytes has biomechanical properties similar to those of natural articular cartilage. Between June 2006 and September 2008 we performed Autologous chondrocyte implantation (ACI) in 50 patients and the chondrocytes were supported in fibrin glue. The cartilage biopsy samples were taken from the nonweight bearing area of the patient's femoral condyle and the samples were transferred to the cell culture laboratory. Chondrocyte were kept in culture about 20 days. Fibrin glue was used as a three dimensional carrier for chondrocyte implantation. A 450 ml of patient's own blood was collected prior to transplantation to produce autologous fibrinogen. Alternatively the allogenic fibrinogen was prepared from Regional Blood Center voluntary donors. Before surgery the chondrocyte suspension was mixed with fibrin glue and gel - like fibrograft was prepared. The total number of cells and the size of fibrograft depended on the defect size in the knee. Our results suggest that ACI technique with fibrin glue is a promising method for treatment of cartilage defect.
