Brief Summary: The primary objective is to determine whether a surgical intervention involving removing of the calcified cartilage cap in patients with Grade II Kellgren-Lawrence osteoarthritis influences the incorporation of labeled bone marrow aspirate concentrate BMAC-derived cells within the cartilage regenerate vs labeled BMAC cells delivered after arthroscopy without removing of the calcified cartilaginous layer The survival and incorporation of the BMAC labeled cells will be evaluated with MRI using the Ferumoxytol infusion stem cell labeling technique The second arm of the study evaluating cell fate after injecting stem cells under a rotator cuff repair will also be explored

The secondary objectives are to 1 determine which surgical intervention leads to better clinical outcomes as measured by Knee Injury and Osteoarthritis Outcome Score KOOS at 12 months and 2 determine who long we can track the labeled-BMAC cells in the knee
Detailed Description: Articular cartilage repair and regeneration has become a focal point for scientists and surgeons in search for a biological treatment for osteoarthritis that has failed non-operative management Surgeons have begun to harvest and centrifuged bone marrow aspirate to produce bone marrow aspirate concentrate BMAC in hopes that the mesenchymal stem cells in the bone marrow aspirate can stimulate cartilage regeneration in areas of articular cartilage deficiency This study is a first-in-human blinded randomized clinical trial using labeled BMAC cells in adults diagnosed with grade II-III Kellgren-Lawrence osteoarthritis

This is a single site study where 20 cases among eligible patients will be identified and randomly assigned to either the control no calcified cartilage or experimental calcified cartilage removed group A power analysis will be performed after 20 patients to determine the total number of patients required to reach adequate power

A patient will receive an infusion of Feraheme 2 days before the procedure and a baseline MR Pelvis and knee A nurse will be present at all times during the infusion to monitor vitals On the day of the procedure patient will undergo harvesting of the bone marrow from the pelvis and arthroscopy procedure involving menisectomy synovectomy and debridement Patients in the experimental group will also undergo removal of the calcified cartilage cap The bone marrow aspirate will be centrifuged and about 5-7 cc of BMAC injected into knee MRIs will be done at the 2 day mark for confirmation of the labeling of the mesenchymal cells and at the two week and 3 month mark Patient related Outcomes will be measured using the Knee injury and Osteoarthritis Score at 12 months follow up
