The use of a pneumatic tourniquet in total knee arthroplasty has been linked to complications caused by local tissue hypoxia. Fat necrosis is a rare condition that presents as an ill-defined subcutaneous lesion. The clinical features resemble that of a lipoma but histological appearance is characteristic. Ultrasound imaging is helpful in establishing the diagnosis both by sonographic appearance as well as in directing a biopsy if necessary. We present a case of encapsulated fat necrosis caused by the use of a pneumatic tourniquet during total knee arthroplasty.
全膝关节置换术中使用气动止血带与局部组织缺氧引起的并发症有关。脂肪坏死是一种罕见的情况,表现为边界不清的皮下病变。其临床特征类似于脂肪瘤,但组织学表现具有特征性。超声成像有助于通过超声表现以及在必要时指导活检来确立诊断。我们报告一例在全膝关节置换术中使用气动止血带引起的包膜性脂肪坏死病例。
