Ligaments and Tendons

Our research and treatment have focused on repair and replacement of the ACL, PCL and reconstruction of the posterolateral corner. 

Our ligament repair technique was developed by Dr. Stone in the early 1990s.  The technique focused on partial ligament tears close to the bony insertion.  By microfracturing the bone, marrow stem cells were released to stimulate healing.  A novel suture technique was then used to place stitches in the torn fibers of the anterior or posterior cruciate ligament and secure it to the bone with a suture anchor.  (see ACL repair page).   Over the years the indications for ligament repair were tightened to only include partial tears right at the bony insertion.

Ligament replacement always involved using the patient's own patellar tendon called bone-patella-tendon bone until approximately 2005.  Once adequate sterilization procedures were introduced to tissue banking Stone  then exclusively used allograft (donor) bone-patella tendon-bone tissue.   The results have been extremely successful and have eliminated the anterior knee pain and weakness from harvesting the patients own tissue.
