This study investigated the incidence and clinical significance of postoperative fever in 118 consecutive patients undergoing 141 total knee arthroplasties (TKAs). A postoperative fever was recorded in 63 (66%) of 95 unilateral and 17 (74%) of 23 bilateral TKA patients. Nine of the unilateral and five bilateral TKA patients developed positive clinical or laboratory findings to explain the pyrexia. Unilateral TKA patients who experienced postoperative fever were statistically more likely to have a complication in the immediate postoperative period. None of the surgical variables examined had any predictive value on the incidence of postoperative fever. Aggressive pulmonary toilet, repeated physical examinations, and urine analysis are recommended when evaluating TKA patients with postoperative fever. Fever following TKA was common and was not necessarily a contraindication to discharge.
本研究调查了118例连续接受141次全膝关节置换术（TKA）患者术后发热的发生率及临床意义。95例单侧TKA患者中有63例（66%）记录到术后发热，23例双侧TKA患者中有17例（74%）记录到术后发热。9例单侧和5例双侧TKA患者出现了阳性临床或实验室检查结果以解释发热。经历术后发热的单侧TKA患者在术后即刻发生并发症的统计学可能性更高。所检查的手术变量均对术后发热的发生率无任何预测价值。在评估有术后发热的TKA患者时，建议积极进行肺部护理、反复体格检查及尿液分析。TKA术后发热很常见，不一定是出院的禁忌证。
