Arm Intervention/treatment
Experimental: OZONE
injection of ozone gas
Device: Ozone gas
Injection of ozone gas intra articularly

Active Comparator: control
injeciton of steroids intra articularly

Primary Outcome Measures :
  1. Improvement in VAS Pain intensity [ Time Frame: 6 months ]
    The outcome measure will be measured according to patient response to the question: during the last week what was your average pain intensity. The response will be measured in millimeters as marked on a 10 cm long line. No pain equals 0 mm and maximal possible pain equals 100mm
