Stem cell therapy is a therapeutic approach often utilized in musculoskeletal system disorders. There are primarily two methods for obtaining and applying these cells.
One method involves obtaining stem cells from bone marrow. These cells can either be multiplied *in vitro* using cell culture techniques in specialized laboratory environments – crucial for preventing disease transmission and ensuring the purity of the transplanted cells – or concentrated directly using advanced centrifugation systems. Once processed, the expanded or concentrated stem cells are integrated into a biological matrix. This matrix, serving as a carrier, is then surgically implanted into the affected joint, often requiring an arthrotomy, and secured with bio-adhesives. The objective of this approach is for the implanted matrix, along with the stem cells, to differentiate into chondrocytes, thereby fostering the regeneration of damaged cartilage tissue. It is important to note that stem cell therapy does not alter the patient's genetic makeup and is distinct from gene therapy.
A more practical, single-session alternative involves utilizing stem cells derived from adipose (fat) tissue. In this method, the fat tissue is harvested, and its stem cell content is concentrated using centrifugation within the same session. The concentrated stem cell suspension is then directly injected into the affected joint. Here, the therapeutic effect relies on the intrinsic ability of the injected cells to home to and initiate repair processes within the damaged area.
The choice between these two methods—bone marrow-derived with matrix implantation versus adipose-derived with direct injection—depends critically on the specific characteristics, size, and nature of the damaged area. A thorough evaluation of the cartilage lesion is paramount, as inappropriate application based on inadequate assessment can lead to suboptimal outcomes. Consequently, meticulous patient selection is a cornerstone for the success of these treatment options.
