    1. Biologic therapy
      1. Review in 12 weeks for improvement of: Atleast 2/4 PsARC criteria(1 of which has to be joint tenderness and swelling score) & no worsening in any of 4 criteria.
        If Pt has no response to PASI (Psoriasis Area and Severity Index) Discontinue Anti-TNF inhibitor used
2. Surgery
3. Podiatric management
  1. Foot orthoses
