Use of Tourniquet During Knee Arthroplasty in Patients With Radiographic Arterial Calcifications

Managing the Patient with Peripheral Vascular Disease before Total Knee Arthroplasty Surgery

Peripheral vascular disease (PVD), defined as decreased arterial perfusion to the lower extremities due to atherosclerotic obstruction, is known to occur in patients undergoing total knee arthroplasty with described rates of between 2% and 4.5% PVD is of significance for patients undergoing TKA as it can increase wound healing and infection complications after TKA and is an independent risk factor for arterial complications following TKA. Our goal is to provide a comprehensive review of the pathophysiology of PVD as it relates to TKA, associated outcomes of patients undergoing TKA in the setting of PVD, diagnostic pearls, and current management strategies recommended in the published literature.
