THE MICROFRACTURE TECHNIQUE FOR THE REPAIR OF PATELLAR CHONDROPATHY LESIONS

Use of a collagen membrane for the treatment of post-traumatic arthrosis of the knee. 

The sheet describes the case of a female patient suffering from post-traumatic arthrosis of the knee with chronic inflammation, characterized by recurring effusions which were periodically treated with arthrocentesis. A lateral parapatellar knee arthrotomy was then performed to extend the external alar ligament, osteotomy of the lateral third of the patella to reduce pressure on the external face, chondroplasty to regularize the surface of the patellar joint, and micro-perforations to stimulate blood supply and decompress the osteonecrosis areas. The procedure was completed by sheathing the surface of the patellar joint with the MeRG collagen membrane (Bioteck), so as to cover the medial and lateral faces of the patella. Before insertion, the membrane was saturated with autologous bone marrow concentrate obtained from the iliac crest. Clinically, an improvement was observed in the mobility of the joint, comparable to that of the right knee, and the resolution of the chronic inflammation of the knee.
