Objective: This study systematically evaluated the effect of intra-articular injection of platelet-rich plasma (PRP) and mesenchymal stem cells (MSC) on knee osteoarthritis (KOA).
Methods: Randomized controlled trials (RCTs) of PRP combined with MSC in the treatment of KOA were collected from PubMed, Cochrane Library, Web of Science, Wiley online library, CNKI, and Wanfang databases from inception to July 30, 2022. Two researchers read and screened the literature to extract the data, respectively. After conducting a risk-of-bias assessment of included data, RevMan 5.3 software was used for meta-analysis. The Cochrane Handbook risk-of-bias assessment tool was used to evaluate the included literature.
Results: A total of 9 papers with 480 KOA patients were included in this study. Significant differences in terms of visual analogue scale (VAS) score (MD = -1.10, 95% CI -1.91 to -0.29), = 0.008) and knee injury and osteoarthritis outcome score (KOOS) (MD = 4.56, 95% CI 0.54-8.58, = 0.050) were noted between the 2 groups. Subgroup analysis found that MD = 1.66 in KOOS-pain-1 group (95% CI (0.10, 3.22), = 0.040), which is significant. The MD for KOOS total score and IKDC scores between the two groups was MD = 6.31 (95% CI 2.73-9.88, = 0.0005) and MD = 3.05 (95% CI -7.09-13.20, = 0.56), respectively.
Conclusion: The results of this study provide a theoretical basis for the clinical treatment of KOA with PRP combined with MSC.

Background: Meniscal injuries that fail to heal instigate catabolic changes in the knee's microenvironment, posing a high risk for developing posttraumatic osteoarthritis (PTOA). Previous research has suggested that human cartilage-derived progenitor cells (hCPCs) can stimulate meniscal repair in a manner that depends on stromal cell-derived factor 1 (SDF-1) pathway activity.
Hypothesis: Overexpressing the SDF-1 receptor CXCR4 in hCPCs will increase cell trafficking and further improve the repair efficacy of meniscal injuries.

Purpose Of Review: Knee osteoarthritis (OA) is a gradual deterioration of articular cartilage characterized by pain and physical dysfunction. Although analgesic pharmacological agents are the first-line treatment for knee OA, they are not effective for all patients. In this study, we evaluate the efficacy of an intra-articular injection treatment using platelet-rich plasma (PRP) in reducing pain and improving functional ability.

Osteoarthritis, particularly temporomandibular joint (TMJ) osteoarthritis (OA), poses significant challenges in diagnosis and treatment. Recent studies suggest that nanomaterials hold considerable promise in treating TMJ-OA, showing validated efficacy in animal models. However, further research is required to ensure their long-term safety within the TMJ-OA environment.

Background: Mitochondrial dysfunction induces chondrocyte senescence, thereby precipitating articular cartilage (AC) degeneration in the pathogenesis of osteoarthritis (OA). Although the transfer of mitochondria from mesenchymal stem cells (MSCs) to host cells and their potential protective role have been demonstrated, whether MSCs can alleviate chondrocyte mitochondrial dysfunction or reverse OA progression remains unclear.
Methods: A mitochondrial tracer was used to investigate the transfer of mitochondria-rich extracellular vesicles (MEV) derived from the culture supernatant of human synovial fluid-derived mesenchymal stem cells (hSF-MSCs).
