Abstract

Knee arthroscopy is a widely performed procedure with few complications and low risk. Vascular complications are also very rare, and pseudoaneurysm is one of the few serious vascular complications. It occurs frequently in the popliteal artery but rarely occurs in the genicular artery. Pseudoaneurysms are caused by damage to the blood vessel wall due to various causes such as trauma and local extravasation. Depending on the size or location, surgical treatments such as intervention embolization or ligation are performed. In this study, after arthroscopic anterior cruciate ligament reconstruction, a pseudoaneurysm of the medial inferior branch of genicular artery occurred near the arthroscopic medial portal site and the lesion was treated successfully with arthroscopic electrocautery.

  Fig. 3 (A) Arthroscopic finding shows hematoma with pseudoaneurysm around the anteromedial portal. (B) After removal, arthroscopic finding shows the absence of hematoma with pseudoaneurysm around the anteromedial portal.
