Development of Novel Strategy for Treatment of Anterior Cruciate Ligament (ACL) Injury Using Stem Cell

A Randomized, Single Center, Investigator Initiated Clinical Trial to Evaluate Enhancement of Healing Between Bone Tunnel and Graft in Anterior Cruciate Ligament (ACL) Injury Using Human Umbilical Cord Blood Derived Mesenchymal Stem Cell

Purpose:Development of novel strategy for treatment of anterior cruciate ligament (ACL) injury using stem cell.

1. Purpose: Development of novel strategy for treatment of anterior cruciate ligament (ACL) injury using stem cell.

2. Subject: Anterior cruciate ligament (ACL) injury 30 patients

   • ACL reconstruction: 10
   • ACL reconstruction + Human cord blood derived mesenchymal stem cells and hyaluronic acid (Cartistem (TM)): 10
   • ACL reconstruction + hyaluronic acid: 10

3. Hypothesis: Human Cord blood derived mesenchymal stem cells can enhance healing between bone tunnel and graft in ACL reconstruction.
