United States Naval Medical Center, San Diego
  Purpose
The purpose of this study is to determine if adding blue dye improves the saline load test, which is a way to detect a traumatic intraarticular knee injury by injecting normal saline into the knee and looking for outflow through the wound.

Enrollment: 60
Study Start Date: May 2008
Study Completion Date: October 2009
Primary Completion Date: October 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Normal Saline
Normal Saline injected intraarticularly into the knee joint
Procedure: Saline Load Test
Intraarticular injection of dilute methylene blue dye (1 ml per 500 ml normal saline) or normal saline into the knee joint through a lateral suprapatellar injection site. Maximum injection of 180 ml.
Experimental: Dilute Methylene Blue Dye
1 ml methylene blue dye per 500 ml normal saline injected intraarticularly into the knee
Procedure: Saline Load Test
Intraarticular injection of dilute methylene blue dye (1 ml per 500 ml normal saline) or normal saline into the knee joint through a lateral suprapatellar injection site. Maximum injection of 180 ml.
