| Abstract | Background Mesenchymal stromal cells (MSCs) are used as an emerging new option for the treatment of knee osteoarthritis (OA). However, their efficacy remains controversial across studies with different doses of MSCs and cell processing methods. We conducted this meta-analysis to assess the efficacy of MSCs in the treatment of knee OA. Methods Randomized controlled trials (RCTs) published in PubMed, Embase, Web of Science, SinoMed (Chinese BioMedical Literature Service System, China), and CNKI (National Knowledge Infrastructure, China) databases were systematically reviewed. The pain level and function improvements were evaluated using visual analog scale (VAS), McMaster Universities Osteoarthritis Index (WOMAC), and International Knee Documentation Committee (IKDC). The pooled estimate was calculated with weighted mean difference (WMD) with 95% confidence intervals (95%CIs). Results Nine RCTs involving 476 patients were included in this meta-analysis. The pooled estimate showed that the treatment of MSCs significantly reduced VAS, WOMAC pain, WOMAC stiffness, and WOMAC function scores at a long-term follow-up (12 or 24 months). However, for the IKDC and WOMAC total scores, MSCs also showed significant improvement in these outcomes, although this was not statistically significant when compared to the control. Conclusion Based on the current studies, our results suggested that MSCs were a promising option for the treatment of patients with knee OA. However, considering the potential limitations, more well-performed, large-scale RCTs are needed to verify our findings. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
