https://www.selleckchem.com/products/erastin.html Mesenchymal stem cells (MSCs) have been investigated for the treatment of knee osteoarthritis because of their unique properties, including self-renewal, multi-linear cellular differentiation, and immunomodulatory capacity. However, the efficacy of MSCs for positive clinical outcomes in the treatment of knee osteoarthritis remains controversial. Because clinical studies in general have high variability, the heterogeneity in the sources of the stem cells used, efficacy of delivery methods, and concomitant surgery should be carefully considered to interpret the benefits of MSC therapy for knee osteoarthritis.The efficacy of mesenchymal stem cells regarding clinical outcomes and cartilage regeneration in knee osteoarthritis remains unclear; however, their theoretical role in multilineage cellular differentiation and immunomodulation of the arthritic cascade has been investigated. Several studies have reported that the use of stem cell therapy for knee osteoarthritis helps in pain improvement, but its effect on cartilage regeneration has not yet been explored. Moreover, numerous studies have reported high heterogeneity in the cell sources, as well as methods of culture expansion or cell concentration, and differences in delivery methods, assessment tools, and concomitant surgical procedures, which could affect the clinical outcomes or evaluation of cartilage regeneration potency. Furthermore, future studies are warranted to examine these factors in detail to interpret the results of mesenchymal stem cell treatment for knee osteoarthritis.Optimal femoral anterior cruciate ligament graft placement has been extensively studied. The champions of transtibial reconstruction debate the backers of anteromedial portal and outside-in drilling. The holy grail is footprint restoration and how we best to get there. To me, creating the femur independently provides the best chance of finding that footprint by being unconstrained by the
