One-Year Functional Evaluation of Patient After CD34+ Stem Cell Treatment for Hip Osteoarthritis

<b>Background/Objectives</b>: The etiology and causes of osteoarthritis are still being studied at the cellular and molecular level by many scientists around the world. With advances in knowledge, technology, and the need for complexity, new therapeutic approaches-such as restorative medicine-are being developed to protect the patient from endoprosthesis implantation, aiming to simultaneously restore and maintain physical and psychosocial function. The purpose of this study was to evaluate the effectiveness of physiotherapy after the implantation of CD34+ stem cells into the hip joints of patients with osteoarthrosis. <b>Methods</b>: The study included 71 patients, previously diagnosed with HOA (hip osteoarthritis) and undergoing CD34+ stem cell therapy followed by rehabilitation. The twelve-month prospective follow-up included 23 women and 48 men. Participants were asked to provide information, regarding the quality of their daily functioning, according to the Harris Questionnaire at four time points. <b>Results</b>: In all evaluations and groups of patients, i.e., women and men, and rehabilitated and non-rehabilitated, a significantly high improvement was noted at 3 months after the administration of CD34+ stem cells, while afterwards there was a slight decrease in the value of the results obtained at 6 months after the procedure, which improved at further stages of the study. The value of functioning on the Harris scale did not differ significantly between genders, although there was a trend of better functioning in men after one year, while it was higher in rehabilitation subjects. <b>Conclusions</b>: Patients' daily functioning was better in the rehabilitation group, as reflected by the Harris scale. The absence of adverse symptoms and the small differences in physiotherapy results between the rehabilitated and non-rehabilitated groups testify to the high effectiveness of the stem cell therapy method.
