Increased Knee Cartilage Volume in Degenerative Joint Disease using Percutaneously Implanted, Autologous Mesenchymal Stem Cells

Background: The ability to repair tissue via percutaneous means may allowinterventional pain physicians to manage a wide variety of diseases includingperipheral joint injuries and osteoarthritis. This review will highlight the developments in cellular medicine that may soon permit interventional pain management physicians to treat a much wider variety of clinical conditions and highlightan interventional case study using these technologiesObjective: To determine if isolated and expanded human autologous mesenchymal stem cells could effectively regenerate cartilage and meniscal tissuewhen percutaneously injected into knees.Design: Case StudySetting: Private Interventional Pain Management practice.Methods: An IRB approved study with a consenting volunteer in which mesenchymal stem cells were isolated and cultured ex-vivo from bone marrow aspiration of the iliac crest. The mesenchymal stem cells were then percutaneouslyinjected into the subject’s knee with MRI proven degenerative joint disease. Preand post-treatment subjective visual analog pain scores, physical therapy assessments, and MRIs measured clinical and radiographic changes.Results: At 24 weeks post-injection, the patient had statistically significant cartilage and meniscus growth on MRI, as well as increased range of motion anddecreased modified VAS pain scores.Conclusion: The described process of autologous mesenchymal stem cell culture and percutaneous injection into a knee with symptomatic and radiographic degenerative joint disease resulted in significant cartilage growth, decreasedpain and increased joint mobility in this patient. This has significant future implications for minimally invasive treatment of osteoarthritis and meniscal injury.Key words: autologous mesenchymal stem cells, osteoarthritis, knee, cartilage
