Hi, You are suffering from ankylosing spondylitis. Bilateral sacroiliacs is sign of this disease. It is one type of chronic inflammatory arthritis affecting large joints. It may spread to involve both hip joints and knee joints. Progress of disease varies in different patients. In long-standing disease hip and spine joints may get fused.  Please visit rheumatologist for detailed examination.  Hope I have answered your query. Let me know if I can assist you further.
