Autologous cellular implant derived from adipose tissue for the treatment of osteoarthritis of the knees; tissue harvesting and cellular implant creation

The procedure described by CPT® Code 0565T involves the use of an autologous cellular implant derived from adipose tissue specifically for the treatment of osteoarthritis of the knees. Osteoarthritis is a prevalent chronic condition characterized by the degeneration of joint cartilage, leading to symptoms such as swelling, stiffness, and pain in the knee joints. As the condition advances, it can result in the formation of bone spurs within the knee, exacerbated by the presence of cytokines and enzymes that further contribute to cartilage degradation. This innovative procedure represents a form of regenerative therapy aimed at alleviating the symptoms of knee osteoarthritis through the utilization of the patient's own adipose tissue. During the procedure, adipose tissue is harvested from the patient, typically from areas with excess fat such as the abdomen, flank, or thigh, using techniques like subcutaneous liposuction. The harvested tissue is then processed to extract mesenchymal stem cells, which are known for their regenerative properties. This processing may involve methods such as centrifugation, sedimentation, or washing and filtration to enhance the concentration of stem cells while eliminating contaminants. Following the preparation of the cellular implant, the procedure includes the implantation of the processed adipose tissue directly into the affected area of the knee, often guided by ultrasound to ensure precision. This approach leverages the higher concentration of stem cells found in adipose tissue compared to other sources, such as bone marrow, making it a promising option for patients suffering from knee osteoarthritis.
