This study is a randomized controlled trial on 60 human subjects with grade 2 and 3 knee osteoarthritis (according to plain radiography) who will be enrolled according to inclusion and exclusion criteria. Patients will be randomly distributed into 4 groups of 15 patients. The initial MRI will be performed for all patients and the patients will be treated as follow: 1) intra-articular injection of mesenchymal cells or MSCs (treatment group) that are isolated from the abdominal wall adipose tissue 2) intra-articular injection of platelet-rich plasma or PRP (treatment group) that are extracted from 100 mL of peripheral blood 3) Intra-articular injection of MSCs in PRP-rich medium (treatment group) and 4) intra-articular injection of hyaluronic acid (control group) which is commercially available. Patients’ follow-ups will be at month 1, 3, 6 and 12 post-treatment. At each follow-up, a clinical examination including range of motion and crepitus of the knee as well as an assessment of patient's health with KOOS (Knee injury and Osteoarthritis Outcome Score) questionnaire and NRS (Numerical Rating Scale) will be performed. Another MRI (second MRI) and a plain standing radiograph of the knee (second radiograph) at 6th month post-injection will be done and the results will be read according to MOAKS (Magnetic resonance imaging Osteoarthritis Knee Score) and K&L (Kellgren and Lawrence) scales. Following the last follow-up, the collected data will be compared and analyzed in a way that firstly, the findings of each patient in each group before and after the intervention will be independently compared, and secondly, the results of each group will be compared with the other three groups.
