Ochronotic arthropathy is a rare condition found in patients with alkaptonuria, which is a hereditary metabolic disease associated with deposition the of homogentisic acid derivatives in various connective tissues of the body. We present the case of a 30-year-old woman in whom arthroscopic examination of the left knee prior to meniscectomy for bucket handle tear of medial meniscus revealed brown-black discoloration of the articular cartilage and menisci leading to the diagnosis of alkaptonuria by further laboratory evaluation. After medical and surgical treatment, patient's complaints were alleviated and no further complaints were registered, during the next follow-up.
