Alkaptonuria is a metabolic disorder characterized by homogentisic acid accumulation in connective tissue. Ochronotic arthropathy, a rare condition reported in alkaptonuria, mostly affects the knee joint. In this study we reported a 57-year-old male patient presented with bilateral hip pain. During the operation, black bone tissue and tendons were observed. We examined the patient for alkaptonuria after the operation and the diagnosis was confirmed. In fact, alkaptonuria was not detected until the operation. Therefore, our study suggests that orthopedic surgeons be suspicious of atypical arthropathy in order to avoid being overwhelmed by the appearance of black cartilage during surgery.
黑尿症是一种代谢紊乱疾病，其特征是结缔组织中尿黑酸积聚。褐黄病性关节病是黑尿症中报道的一种罕见病症，主要影响膝关节。在本研究中，我们报告了一名57岁男性患者，他出现双侧髋关节疼痛。手术过程中，观察到黑色骨组织和肌腱。术后我们对该患者进行了黑尿症检查，确诊了该病。事实上，直到手术时才检测到黑尿症。因此，我们的研究表明，骨科医生应对非典型关节病保持怀疑，以免在手术中被黑色软骨的外观所迷惑。
