INTRODUCTION
Ochronotic arthropathy in patients with alkaptonuria is a rare hereditary disorder. The altered metabolism causes the homogentesic acid derivatives to deposit in various connective tissues causing characteristic pigmentation. Due to the close clinical resemblance to that of a degenerative disorder, diagnosis of ochronotic arthropathy usually occurs intraoperatively. We report arthroscopic findings of a 50-year-old female with ochronotic arthropathy.
CASE REPORT
A 50-year-old woman came with complaints of pain and swelling in the left knee. Clinical examination and MRI findings were correlated to reveal a tear of lateral meniscus. On arthroscopic examination, the blackish pigmentation of the meniscus and the articular cartilage led to the diagnosis of ochronotic arthropathy.
CONCLUSION
Arthroscopy plays an important role in diagnosis and treatment of patients with ochronotic arthropathy. The characteristic arthroscopic finding may aid diagnosis even in patients who do not have other systemic manifestations. Timely arthroscopic intervention can help delay the disease progression.
引言
尿黑酸尿症患者的褐黄病性关节病是一种罕见的遗传性疾病。代谢改变导致尿黑酸衍生物沉积在各种结缔组织中，引起特征性色素沉着。由于其临床表现与退行性疾病极为相似，褐黄病性关节病的诊断通常在手术中进行。我们报告了一名50岁患有褐黄病性关节病女性的关节镜检查结果。
病例报告
一名50岁女性因左膝疼痛和肿胀前来就诊。临床检查和磁共振成像（MRI）结果相互印证，显示外侧半月板撕裂。关节镜检查时，半月板和关节软骨的黑色色素沉着确诊为褐黄病性关节病。
结论
关节镜检查在褐黄病性关节病患者的诊断和治疗中起着重要作用。即使在没有其他全身表现的患者中，特征性的关节镜检查结果也有助于诊断。及时的关节镜干预有助于延缓疾病进展。
