Ochronosis: Complicated Tear of Black Meniscus

Abstract

We describe a case of a previously healthy 35-year-old man who presents with meniscal symptoms, and present the arthroscopic findings of a complicated tear of black lateral meniscus. Investigations revealed that he had underlying alkaptonuria, which was previously undiagnosed without any other findings. After the surgical treatment, the patient's complaints were alleviated and almost no complaints were registered, during the next follow-up.
