Infection of a total knee replacement (TKR) is a very serious complication of knee arthroplasty surgery as the repercussions for the patient often include long-term antibiotics, further surgery, revision surgery, and worse outcomes in the long-term including increased morbidity and mortality. As such, the careful assessment of a patient presenting with an acutely inflamed TKR is of paramount importance.
We report a case of a patient presenting with the clinical signs and symptoms of an acute infection of their TKR. The patient was ultimately diagnosed as having pseudogout.
This case illustrates that crystal arthropathy must be one of the differential diagnoses for a suspected infection of a TKR, as failure to recognize this may result in unnecessary and detrimental treatment.
全膝关节置换术（TKR）感染是膝关节置换手术一种非常严重的并发症，因为对患者的影响通常包括长期使用抗生素、进一步手术、翻修手术，以及长期更差的预后，包括发病率和死亡率增加。因此，对急性炎症性全膝关节置换术患者进行仔细评估至关重要。
我们报告一例患者，其表现出全膝关节置换术急性感染的临床症状和体征。该患者最终被诊断为假性痛风。
本病例表明，结晶性关节病必须作为全膝关节置换术疑似感染的鉴别诊断之一，因为未能识别这一点可能导致不必要的有害治疗。
