False Aneurysm Following Total Knee Replacement

Abstract

Arterial injuries following total knee replacement (TKR) are uncommon and almost always occlusive in nature. Rand reported an 0.03% incidence of vascular complication in 9022 cases, 2 of which lead to below knee amputation (1). The popliteal vessels lie posterior to the surgical exposure and are usually protected from injury. Injuries to the genicular artery network around the knee joint during TKR are common rather than exception. These injuries usually do not cause any untoward effects but may lead to hemorrhage and rarely periarticular or intraarticular aneurysms presenting with a pulsatile mass. We wish to report a case of pseudoaneurysm which arose from the lateral geniculate artery and presented with a pulsatile mass following revision TKR.
