Official Title: Multicenter, Randomized, Open-Label, Standard Treatment-Controlled Parallel Group Phase 2 Study to Evaluate Efficacy and Safety of Intra-Articular Injections of Autologous Peripheral Blood Stem Cells
Brief Summary: This is a 24-month, multicenter, randomized, open-label, standard treatment-controlled, parallel-group, Phase 2 study for adults with large or complicated knee articular cartilage lesions and are candidates for knee joint cartilage repair surgery. The safety and efficacy of intra-articular injections of peripheral blood stem cells (PBSCs) together with hyaluronic acid (HA) after subchondral drilling surgery will be evaluated to determine whether PBSC therapy can improve functional outcome and reduce pain of the knee joint better than a standard treatment (HA injections and physiotherapy regimen).
