Ozone Therapy in the Treatment of Osteoarthritis B. Conde, M. Casas, M. Delgado, F. Ramos. Camilo Cienfuegos Provincial Hospital Sancti Spiritus, Cuba. We have been using ozone therapy, during 5 years, in 200 patients with different types of arthritis, for example: lumbar arthritis, generalized arthrosis, hiposteoarthritis, knee arthrosis. In our group of patients, 60 % female and 40 % of male were present (80 % with more than 40 years old). Three groups of treatment were considered: group I , using ozone therapy alone; group II, ozone therapy plus medication (antinflamatory and/or analgesics drugs) and group III, ozone therapy plus medication and physiotherapy. In general. 85 % of improvement was obtained. Source: 2nd International Symposium on Ozone Applications Havana, Cuba - Mach 24-26, 1997.
