Accumulation of irrigation fluid in the calf as a complication during high tibial osteotomy combined with simultaneous arthroscopic anterior cruciate ligament reconstruction.

Abstract

Extravasation of irrigation fluid during arthroscopy is a well-known complication. We report a case of accumulation of fluid into the calf during open wedge high tibial osteotomy combined with simultaneous arthroscopic anterior cruciate ligament (ACL) reconstruction. The main cause for fluid extravasation was the drilling of the tibial tunnel, which allowed the fluid to cross the osteotomy gap and invade the flexor compartments. Although an elevation of the intracompartmental pressure was measured, there was no clinical evidence of compartment syndrome. A subcutaneous release of the flexor compartment of the leg was performed. The patient suffered no further sequelae. High tibial osteotomy combined with simultaneous arthroscopic ACL reconstruction has to be performed carefully, and potential complications must be detected immediately to prevent compartment syndrome.
