CRUZ-SANCHEZ, Pedro M et al. Impact of the treatment with adult stem cells in knee osteoarthrosis. Rev Cubana Hematol Inmunol Hemoter [online]. 2013, vol.29, n.3, pp. 272-283. ISSN 0864-0289.

Introduction: osteoarthrosis an every day more frequent degenerative disease affecting the quality of life of people over 55 years old and its treatment is a great challenge. The use of stem cells has open a new alternative in the available therapeutic arsenal. Objective: to assess the efficacy and safety of autologous adult stem cell transplantation in the treatment of knee osteoarthrosis. Methods: the study took place from May 2009 to December 2011 in 123 adult patients with OAR from the regenerative medicine outpatient service who had no response to conventional treatments. Intra-articular implantation of autologous peripheral blood mononuclear cells (MNC-SP) mobilized by granulocyte colony stimulating factor was performed. In all cases pain and gait difficulty at baseline prevailed. Results: after six months, clinical and radiological improvement in 117 patients (95,1 %) were observed and only in six patients (4,9 %) the expected response was not obtained. These last patients presented marked alignment disorders and the pain did not disappear, but there was a positive change in its intensity. Conclusions: the CMN-SP implant is a feasible, simple, safe and less expensive method for the treatment of knee osteoarthrosis. It is recommended that in cases with marked angular deformity, this disorder should be corrected prior to MNC-SP implantation so the procedure be successful.
