Popliteal artery damage during total knee arthroplasty.
Injury of popliteal artery during total knee arthroplasty is a relatively rare complication. We report on one case of transverse semi-dissection of the popliteal artery during the tibial cut and one case of popliteal pseudoaneurysm formation caused by Hohmann retractors. Diagnosis was made early in the first case but it was delayed in the second due to misdiagnosis of deep vein thrombosis. Both injuries were managed eventually by open surgery. Postoperative clinical examination and ultrasound imaging confirmed the successful restoration of the blood flow. This case report also describes the classification system of the type of vascular damage and describes the mechanism, the clinical presentation, diagnostic modalities and treatment options for these rare complications of total knee arthroplasty surgery.
