This is a 2 phase study, where phase 'A ' is blinded and phase 'B' is open labelled (not blinded). In first phase, participants will be randomized to receive either emu oil or placebo for 8 weeks and the arm to which they are randomized will not be known to them or their doctor. During this treatment period, all patients would be required to mainatain daily diary to record treatment compliance. Joint pain and stiffness severity will be assessed before and after treatment using pain questionnaires. In phase B, patients will be asked to continue treatment with open label emu oil for further 8 weeks, if they wish. All patients continuing in phase B, will be assessed for pain and stiffness severity at the end of this phase. Following 16 weeks of treatment, patients will be able to continue with commercial stock of emu oil, and will be assessed for compliance and severity at 6 months. Improvement in joint pain and stiffness will be assessed at baseline and end of 8 weeks of treatment. Adverse events and compliance related to Emu oil will be monitored throughout the study.
