 Abstract

  Alkaptonuria is a rare autosomal recessive disorder characterized by deficiency of homogentisic acid oxidase. This deficiency leads to accumulation of homogentisic acid in tissues and its urinary excretion and resulting in characteristic features like ochronosis, darkening of urine, and arthropathy. We describe a case of alkaptonuric ochronosis in a 62 year old man, who had alkaptonuria, degenerative arthropathy of hip and knees, spinal abnormalities similar to ankylosing spondylitis and renal calculi.Total replacement of hip joint was done. Total replacement of hip joint was done.
