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.

Outcome Measures
Primary Outcomes (1)
Integration of the mesenchymal stem cells.
Number of integrated labeled mesenchymal stem cells in the cartilage regenerate counted from from MRI imaging.
3 months
Secondary Outcomes (1)
Knee Injury and Osteoarthritis Outcome Score (pain subscale)
12 months
Study Arms (2)
arthroscopy with removal of calcified cartilage
EXPERIMENTALThis arm will have patients who will get surgical intervention (menisectomy, synovectomy and debridement) along with removal of the calcified cartilage layer. The patients will also get 5 cc of BMAC produced from The Harvest/Terumo BCT system.
arthroscopy without removal of calcified cartilage
ACTIVE COMPARATORThis arm will have patients who will get surgical intervention (menisectomy, synovectomy and debridement) but with retention of the calcified cartilage cap. The patients will also get 5 cc of BMAC produced from The Harvest/Terumo BCT system.
Interventions
Subjects will undergo knee arthroscopy for debridement, menisectomy and synovectomy of the cartilage defects. Subjects will also be injected with bone marrow aspirate concentrated harvested from the pelvis and centrifuged (produced produced using the Harvest/Terumo BCT system)
