Does tourniquet use during anterior cruciate ligament surgery interfere with postsurgical recovery of function? A review of the literature.

Abstract

This article explores the issue of whether use of a tourniquet during arthroscopically assisted repair of the anterior cruciate ligament (ACL) slows the postoperative recovery of function. A tourniquet is customarily used to provide a bloodless field, thus enabling the surgeon to visualize the joint clearly. However, there is increasing evidence that tourniquets cause muscle and nerve damage that can have long-term consequences for the recovery of function following surgery. The two randomized trials that investigated tourniquet use during meniscectomy reached contradictory conclusions about the effects of the tourniquet. There have been no randomized trials of tourniquet use during the longer and more complex ACL surgery. This article reviews the pertinent literature and suggests some clinical implications of the available information.
