INTRODUCTION
Regional migratory osteoporosis (RMO) is an unusual phenomenon characterized by migrating arthralgia of the lower limbs due to underlying bone marrow edema.
CASE REPORT
We discuss a 57-year-old male with a 3-month history of atraumatic medial knee pain. Magnetic resonance imaging demonstrated bone marrow edema of the medial femoral condyle that resolved with rest and simple analgesia, followed by posterolateral knee pain and similar imaging changes in the lateral femoral condyle.
CONCLUSION
Most cases of RMO spontaneously resolve with limitation of weight-bearing and simple analgesia. For recurrent cases, surgical intervention may be required.
引言
区域性迁移性骨质疏松症（RMO）是一种不寻常的现象，其特征是由于潜在的骨髓水肿导致下肢关节疼痛迁移。
病例报告
我们讨论一名57岁男性，有3个月无创伤性膝关节内侧疼痛病史。磁共振成像显示股骨内侧髁骨髓水肿，通过休息和简单止痛治疗后缓解，随后出现膝关节后外侧疼痛，且股骨外侧髁有类似的影像学改变。
结论
大多数RMO病例通过限制负重和简单止痛可自发缓解。对于复发病例，可能需要手术干预。
