Surgical Technique Intrinsic in Primary Anterior Cruciate Ligament Reconstruction from 2007 to 2014

Really interesting article in general of bone and joint surgery this month. 

Surgical Technique Intrinsic in Primary Anterior Cruciate Ligament Reconstruction from 2007 to 2014.
Jbjs. 2016,981079-89

The article reviews 21,686 anterior cruciate ligament reconstructions done in the Kaiser system from 2007 to 2014.

During that time femoral tunnels started out mostly being drilled through the tibial tunnel and then transitioned to being mostly drilled through a medial portal or through a lateral approach.

Graft types remained basically stable with a little more than 30% hamstrings and about 25% patellar tendon with the remaining being various types of allografts.

Fixation types changed but in multiple directions with different graft types using either more or less metal and multiple types of  bioabsorbable vs biostable polymer devices.

The outcome measured was cumulative rates of revision. The rates of revision were not broken down by graft type etc. so this is a broad overall look to see if the trends for how ACL’s were done over that 7 year period resulted in a change in results.

The cumulative revision rates measured 2 years out remain essentially the same with all of these changes.

Lots of action, but not much movement.
