That bloody knee! Dealing with an organized hemarthrosis.

Abstract

The decision to manage an organized hemarthrosis conservatively or surgically is difficult and still controversial, especially in the postoperative patient compared with the trauma patient. We describe a cheap, effective, and readily available technique for the surgeon who elects for a surgical solution to this problem using a Karman catheter (Rocket Medical PLC, Watford, UK) during arthroscopy to complete an irrigation and vacuum circuit.
