Arterial complications after total knee arthroplasty (TKA) are rare; however, the sequelae can be disastrous. Infection and the need for amputation or vascular reconstructive surgery are not uncommon. A thorough preoperative assessment can identify at-risk patients, many, if not all, of whom have preexisting peripheral arterial disease. In the presence of peripheral arterial disease, the use of a tourniquet during TKA has been implicated in subsequent arterial complications. Following the guidelines that have been established regarding preoperative assessment, the role of the vascular surgeon, and the use of a tourniquet before and during TKA can assist the orthopaedic surgeon in assessing candidates for TKA and reducing the risk of arterial complications.
全膝关节置换术（TKA）后的动脉并发症很少见；然而，其后果可能是灾难性的。感染以及截肢或血管重建手术的必要性并不罕见。全面的术前评估可以识别出高危患者，其中许多（如果不是全部）患者都有先前存在的外周动脉疾病。在外周动脉疾病存在的情况下，TKA期间使用止血带与随后的动脉并发症有关。遵循已确立的关于术前评估、血管外科医生的作用以及TKA术前和术中止血带使用的指南，可以帮助骨科医生评估TKA候选者并降低动脉并发症的风险。
