Arthroplasty Using Autologous Multipotent Mesenchymal Cells and Collagen Membrane Chondro-Gide

Surgical treatment results for 13 patients with local deep defects of the articular surface of femoral condyle are presented. Surgical treatment was performed in two steps. At first step diagnostic arthroscopy with removal of loose intraarticular bodies, resection of injured menisci and harvesting of fat body tissues for multipotent mesenchymal stromal cells (MMSC) isolation were applied. Second step consisted of knee arthroplasty; zone of defect was covered with collagen membrane Chondro-Gide under which MMSC were implanted. Control arthroscopy with biopsy of articular surface fragment in the zone of defect restoration was performed to four patients (30.8%) 2 years after arthroplasty. It is shown that after surgical intervention cartilage regeneration goes on owing to fibrillar cartilage formation. In 2 years follow up good results were achieved in 92.3% of cases that proved the efficacy of the elaborated technique for restoration of knee joint function and slowing down of degenerative-dystrophic changes development
