Intraarticular pressures in a gravity-fed arthroscopy fluid delivery system.
Seven consecutive patients undergoing arthroscopic surgery in a gravity-fed fluid delivery system were studied. The average minimum adequate intraarticular pressure (MAIP) was 55 mm Hg. The height of a saline bag above the knee necessary to achieve this average MAIP was 75 cm. There was a positive correlation between diastolic blood pressure and the minimum adequate intraarticular pressure in this study. There was no positive correlation between systolic blood pressure and the MAIP.
