Use of tourniquet in anterior cruciate ligament reconstruction: Is it truly necessary? A prospective randomized clinical trial

Is a Tourniquet Necessary for ACL Reconstruction? A Study Overview

Purpose of the Study

This study looked at whether using a tourniquet during arthroscopic anterior cruciate ligament (ACL) reconstruction is beneficial. We focused on:

  • Intraoperative visualization
  • Surgical time
  • Use of sterile saline
  • Postoperative pain

Study Methodology

In this clinical trial, patients were split into two groups: one that used a tourniquet and one that did not. We measured:

  • Visibility during surgery (rated from 0 to 10)
  • The time taken for surgery
  • The amount of saline used
  • Pain levels 24 hours after surgery

Key Findings

We included 71 patients in the No Tourniquet group and 75 patients in the Tourniquet group, with similar average ages. Here are the main results:

  • Surgical Time: No significant difference (51.07 min vs. 50.03 min)
  • Saline Consumption: Comparable amounts used (6.17 L vs. 5.89 L)
  • Visibility Scores: Both groups had excellent visibility (65.49 vs. 65.39)
  • Postoperative Pain: Lower in the No Tourniquet group (VAS score of 2.82 vs. 5.80)

Conclusions

Using a tourniquet during ACL reconstruction does not enhance visibility or reduce surgery time. However, it is associated with increased postoperative pain and potential complications.

Clinical Implications

This study highlights the importance of evaluating surgical practices to improve patient outcomes. By avoiding unnecessary tourniquet use, we can enhance recovery and reduce pain for patients.
