Thromboembolic Events After Arthroscopic Knee Surgery: Increased Risk at High Elevation.

Purpose: To evaluate the incidence of thromboembolic events in patients undergoing arthroscopic surgery of the knee in centers located at elevations near sea level and compare those rates with the patients undergoing the same operations in centers at high elevation.

Methods: A retrospective review was conducted using a database of a major health care system with surgery centers located throughout the United States. More than 115 centers located in 15 different states were analyzed for any reported thromboembolic events including deep vein thromboses and pulmonary embolism (PE) in patients who had undergone knee arthroscopy over a 2-year period.
