Case in brief
A 56-year-old male with traumatic arthritis underwent total knee replacement and developed a popliteal artery pseudoaneurysm four days post-surgery, presenting with sudden tearing pain during knee flexion. Vascular CT angiography confirmed the diagnosis, leading to surgical intervention to remove the pseudoaneurysm. Postoperatively, the patient showed significant improvement in symptoms and joint activity after one month.
Diagnostic / clinical pearl
Clinicians should be aware of the risk of popliteal artery pseudoaneurysm in patients with severe knee deformities undergoing early rehabilitation after total knee replacement.
Why it matters
This case highlights the need for careful consideration of rehabilitation protocols to mitigate risks while promoting recovery in postoperative patients.
