Arthroscopic diagnosis and management of ochronotic arthropathy of the knee.
Ochronotic arthropathy is a progressive joint disorder resulting from the deposition of a derivative of homogentisic acid into connective tissues, especially meniscal and articular cartilage. Patients may present with symptoms, physical examination results, and radiographic changes consistent with degenerative joint disease. We present a case in which an operative arthroscopy of the knee was highly suggestive of ochronotic arthropathy. The definitive diagnosis of ochronosis was subsequently confirmed by laboratory and pathologic evaluation.
