- Vangsness CT, A Randomized Clinical Trial Using Mesenchymal Stem Cells for Meniscus Regeneration and Osteoarthritis, double-blind human trial, 55 subjects, meniscus tears, statistically significant reduction in pain from Stem cells compared to placebo; degenerative bone changes 3.5 times more likely with placebo then stem cells; No serious adverse effects observed at 2 years post treatment.
- A number of clinical trials are in progress, not many have been completed with definitive results yet.

Epub 2011 Dec 18. Only 8 patients; statistically significant improvements in clinical scores; 7 out of 8 patients thought procedure excellent and would do it on their other knee if needed
- Gobbi A, One-Step Cartilage Repair with Bone Marrow Aspirate Concentrated Cells and Collagen Matrix in Full-Thickness Knee Cartilage Lesions. Results at 2-Year Follow-up. Patients showed significant improvements. MRI showed tissue regrowth in all patients. No adverse reactions or post-operative complications noted.

- Marcus Jager, Bone Marrow Concentrate: A Novel Strategy for Bone Defect Treatment, Current Stem Cell Research & Therapy, 2009, 4, 34-43. Transplantation of Bone Marrow Aspirate was able to facilitate healing of volumetric bone loss. All patients showed bone healing and/or sufficient new bone formation.
- Fortier L, Concentrated Bone Marrow Aspirate Improves Full-Thickness Cartilage Repair Compared with Microfracture in the Equine Model, 2010 Journal Of Bone and joint Surgery. Bone Marrow Concentrate can result in healing of acute full-thickness cartilage defects superior to microfracture alone in an equine model. MRIs showed increased fill of defects and improved integration of repair tissue into surrounding normal cartilage.
