title: Case report: diabetic muscle infarction presenting as knee arthralgia.
abstract: Diabetic muscle infarction is a rare complication of diabetes and has characteristic clinical features including acute onset of pain with painful swelling, most commonly in the thigh or calf muscle, which gradually improves to complete resolution. Recently we experienced a case of diabetic muscular infarction presenting as knee joint pain due to involvement of the proximal portion of the leg muscle, which site has not been reported previously. This case shows that diabetic muscle infarction may involve sites other than the thigh and calf areas and should be considered in the differential diagnosis of knee arthralgia.
