Objective: To compare the effect of intraarticular injection of Ozone and steroids in improvement of clinical and cellular healing of knee osteoarthritis.
Methods: in a randomized clinical trial, 70 patients with knee osteoarthrosis were included in the study. In Ozone group, 5 ml (35 ?g/ml) of Ozone and in steroid group 5ml (50 mg) Triamcinolone were injected intraarticular. At 1,2,and 6 month patients were followed for pain scale, disability index and IL-1? and TNF-? serum levels were measured.
Results: At 1 month after injection pain scale and disability index and IL-1? and TNF-? were decreased in both groups. However, at 2 and 6 month pain scale and disability index were significantly lower in Ozone group compare to steroid group (p
