Complications associated with the use of an infusion pump during knee arthroscopy.

This is a report of four complications from the use of an automated arthroscopy pump in 283 patients undergoing knee arthroscopy. The first patient had extravasation of fluid into the thigh, requiring discontinuation of the procedure. The second patient developed a compartment syndrome of the leg, necessitating a four-compartment fasciotomy of the leg. The third patient developed severe fluid extravasation into the anterior thigh compartment. A limited fasciotomy of the anterior thigh compartment was performed. The fourth patient developed moderate extravasation into the anterior part of the thigh and groin, necessitating discontinuation of pump irrigation and conversion to gravity irrigation to complete a partial medial meniscectomy. During a 15-month period, a complication rate of 1.4% from fluid extravasation during knee arthroscopy was noted. This review represents our initial experience with the infusion pump. No cases of fluid extravasation have occurred subsequently during a 12-month period.
