METHOD OF TREATMENT OF OSTEOCHONDRITIS DISSECANS OF THE KNEE JOINT Russian patent published in 2018 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to traumatology and orthopedics, and may be applicable for the treatment of osteochondritis dissecans of the knee joint. Make liposuction of fatty tissue from the anterior abdominal wall, and/or the gluteal region, and/or the outer surface of the thighs. Autologous fat tissue is sampled. Cells of the stromal vascular fraction (SVF) are obtained. Endoscopic examination – arthroscopy of the knee joint – is performed, localization, size, stability of the osteochondral fragment are determined. Perform a mini-arthrotomy. Make a fragment of tunneling through the cartilage plate. Separate the osteochondral fragment from the bed. Remove the necrotic bone. Perform multiple, at least 5 holes, tunneling of the bone defect area to a depth of 1 cm or more in different directions. Bone grafting is performed using demineralized bone grafts impregnated with autologous SVF of adipose tissue, cells of the SVF are injected simultaneously with fibrin glue using the duploject system, exactly in the area of the bone defect. Osteochondral fragment set in place. Perform 8–10 cycles of passive flexor-extensor movements in the joint. Wound is sutured in layers.

EFFECT: method provides engraftment of the osteochondral fragment.
