Abstract:

Knee osteoarthritis characterized by articular cartilage degeneration, meniscus wear and osteophyte formation is a degenerative disease of articular cartilage that is common in middle-aged and elderly people. Because of the lack of nourishment of nerves and joint microvasculature, articular cartilage can hardly heal or repair itself after undergoing degenerative changes. The effect of conservative treatment is unsatisfactory, and joint replacement has to be taken in late-stage and severe cases. Mesenchymal stem cells (MSCs) are reliable materials for tissue regeneration and repair because of multilineage differentiation potential and strong paracrine capacity. MSCs can be derived from fat, bone marrow and umbilical cord. Generally, it is separated and amplified in vitro, and injected into the knee joint cavity to improve arthritic symptoms. Numerous clinical trials of MSCs in the treatment of knee osteoarthritis have demonstrated its efficacy. This article collects literature and clinical trials of MSCs in the treatment of knee osteoarthritis from 2017 to 2020, through Pubmed, domestic literature database and clinicaltrials.gov. We also review the clinical research results, treatment effects, existing problems and development prospects.

Key words: Mesenchymal stem cells, Knee osteoarthritis, Intra-articular injection
