摘要

Knee pain is a common complaint in rehabilitation outpatient clinics. Plain radiography is typically used to detect knee pain and trauma. However, a slight depression plateau fracture could be easily overlooked on plain radiography. This is a case report of a 57-year-old woman with left knee pain who visited the outpatient clinic for help. Ultrasonography showed fat-fluid level, but plain radiography did not reveal any fracture. Magnetic resonance examination confirmed the depression fracture of the tibial plateau and the lipohemarthrosis. Lipohemarthrosis is a highly sensitive predictor of intra-articular surface fractures. Ultrasound is a convenient and reliable tool to detect lipohemarthrosisof the knee, implying further evaluation, especially if plain radiography is negative or uncertain.

膝蓋疼痛是復健科門診常見的問題。X光常用於檢查膝蓋的創傷與疼痛，但對於一些輕微壓迫的脛骨平台骨折常不易檢查出來。本次案例為一位57歲的女性左膝疼痛前來就診。超音波下看到多層的關節積液，但X光未看到明顯的骨折。經由核磁共振診斷脛骨平台骨折合併有關節積血及脂肪。關節積血及脂肪常暗示關節腔內骨折的情形。當超音波發現關節積血及脂肪，但X光上無明顯骨折時，應更進一步安排檢查。
