A 34-year-old male patient presented to the surgeon’s attention complaining of pain and loss of joint function at the level of the right knee. MRI analysis confirmed cartilage damage at the level of the patella extending from the lateral facet to the medial facet through the vertex, grade IV on the Outerbridge scale.
The treatment plan involved harvesting bone marrow concentrate from the iliac crest, depositing it into the cartilage defect to be regenerated, supported by the MeRG bi-layer collagen membrane. The membrane is used for the purpose of providing a biological chamber within which the rooting and proliferation of mesenchymal cells from the bone marrow concentrate is promoted. In addition, the use of the membrane supports the stabilization of the blood clot, thereby facilitating the formation of new cartilage filling tissue.
