Objective: To determine the efficacy of intra-articular knee infiltration with medical ozone in patients with chronic knee pain due to knee osteoarthritis. Methods: An observational, prospective and intrasubject, included 203 patients with knee osteoarthritis and pain secondary to most, there were a total of five intra-articular injections with medical ozone at a concentration of 25 ug / ml and a volume of 10 ml at weekly intervals. Analgesic quality was evaluated by visual analogue scale (VAS) and pain (WOMAC-A), stiffness (WOMAC-B) and functional capacity (WOMAC-C) using the questionnaire Western Ontario and McMaster Universities Osteoarthritis (WOMAC) before and after treatment. Results: 203 patients were performed a total of 305 procedures, 204 women and 101 men, with a mean age of 69.9 ± 9.4 years. Giving to EVA, WOMAC-A,-B and WOMAC WO-MAC-C range of quantitative variables, the mean pre-treatment were 6.

In recent years, different studies have observed a strong association between chronic pain (CP) and psychological trauma. Therefore, a trauma-focused psychotherapy, such as eye movement desensitization and reprocessing (EMDR), could be an innovative treatment option. The aim of this pilot study was to assess whether a specific EMDR protocol for CP leads to (a) a reduction in pain intensity, (b) an improvement in anxiety and depressive symptoms, and (c) an improvement in quality of life. About 28 CP patients were randomly assigned to EMDR + Treatment as usual (TAU; n = 14) or to TAU alone (n = 14). Patients in the EMDR group received 12 psychotherapeutic sessions of 90 minutes over 3 months. Pain intensity was measured using the Visual Analog Scale and the Pain Disability index, quality of life using the EQ-5D-5L, and anxiety and depressive symptoms using the Hamilton Anxiety and Depression Scale. Measures were taken for both conditions at pre- and post-treatment, and a follow-up in the EMDR condition was taken at 3 months post-treatment. Patients in the EMDR group showed significantly reduced pain intensity and improved quality of life and anxiety and depressive symptoms compared to TAU alone at post-treatment. Improvements were largely maintained at 3-month follow-up. This study suggests that EMDR may be an effective and safe psychological intervention to be used within the multidisciplinary treatment plan of patients with CP.
