Welcome to e health forum.

Intra-articular venous malformations (IAVM) of the knee represent a rare group of low-flow vascular malformations, mainly presenting as synovial hemangiomas, usually with an onset in early childhood. The main symptoms and signs are knee pain, swelling, and hemarthrosis. These lesions are slowly progressive and can lead to chronic synovitis and joint damage.

Surgical excision is always indicated and should be performed as early as possible to avoid lesion progression and to reduce the risk of chondral degeneration.

Surgical resection is the only potential cure; however, it is often difficult to perform and carries a risk of massive hemorrhage.

To minimize complications related to surgery, aggressive control of blood flow to the lesion, preoperatively, with appropriate embolotherapy is essential, and a complete resection with a chance of cure will be increased.
