Summary

The goal of this clinical trial is to pharmacologically evaluate the effects of culturued allogeneic umbilical cord blood-derived mesenchymal stromal stem cell (UCB-MSCs) in the treatment of end-stage knee osteoarthritis (Kellgren-Lawrence grade 4) with the analysis of soluble biomarkers and expression of key genes, as well as the evaluation of clinical outcomes with patient-reported outcome measures (PROMs) and recording of potential complications. Patients will be randomized in the intervention and control groups. In both groups, the knee aspiration will be performed 4-6 weeks prior to the knee arthroplasty to analyse baseline synovial fluid characteristics. The intervention group will receive the injection of UCB-MSCs. All patients will complete PROMs questionnaires and maintain a pain diary on visual analogue scale (VAS) at home until the surgery. On the day of admission to hospital for knee arthroplasty, the same questionnaires will be administered again. During the operative procedures, the samples of synovial fluid, synovial membrane and resected cartilage will be obtained and analysed afterwards. It is anticipated that the study results will contribute to elucidate the mechanisms of action of MSCs in the treatment of knee osteoarthritis.
