Abstract (original English)

Background/Objectives: In 2020, 595 million world citizens had osteoarthritis, and the largest growth in OA morbidity refers to the hip joint. Effective OA therapies have been sought for years. Assessing the treatment effectiveness and QoL improvement in hip OA after intra-articular administration of fresh peripheral blood hematopoietic CD34+ stem cells. Methods: The study comprised 49 adults (median age: 63). The SCs were injected into hip joints and straight to the bone. Hip manipulation was conducted. Patients were subjected to a standardized rehabilitation protocol. Hip degeneration was graded by Kellgren-Lawrence. Multi-factor statistical analyses, with replications, were performed. The study was an R&D project, co-financed by the E.U. Results: Patient-reported outcomes (HOOS, SF-36) ameliorated remarkably over 24 months ( p p Conclusions: Intra-articular administration of CD34+ cells significantly reduces pain and improves hip joint function, regardless of the severity of OA, according to K-L, over a 24-month follow-up period. The combination of CD34+ cell therapy with joint mobilization and rehabilitation allows for the postponement of hip arthroplasty by significantly improving patients' QoL over the 24-month follow-up period.
