title: Ochronotic arthropathy: arthroscopic findings in the shoulder and the knee.
abstract: Ochronotic arthropathy is a disorder resulting from the deposition of homogentisic acid derivatives in the articular cartilage and the menisci. Large joints of the appendicular skeleton are preferentially affected. The clinical picture resembles that of degenerative joint disease. We present the arthroscopic findings in the shoulder and the knee in a 40-year-old man with ochronotic arthropathy and discuss the role of arthroscopy in the diagnosis and management of this rare metabolic disorder.
