[Extra-articular recurrent bleeding from the medial retinaculum]

A young woman had subcutaneous bleeding at the retinaculum of the left knee after minor trauma. A small vein was attached to the scar and repeatedly ruptured after several other small traumas. Conservative therapy had no impact on the genesis of the bleeding. Having gone through severe bleeding situations with massive swelling of the knee five times in a row, the patient underwent surgical exploration.The source of recurrent bleeding, a small vein, could be identified and excised. After that no further bleeding episodes took place.
