Arthroplasty for the treatment of joint degeneration caused by ochronosis in two cases

Acta Orthopaedica et Traumatologica Turcica, 2020
Ochronosis is a rare metabolic disease caused by the deficiency of the homogentisic acid oxidase enzyme. With increasing age, accumulation of pigment deposits of homogentisic acid in the joint cartilage results in ochronotic osteoarthritis.
