Commercially Available Guides Overestimate Socket Length During Anterior and Posterior Cruciate Ligament Socket Retrograde Drilling.

Purpose: To objectively assess the accuracy of socket measurements taken during cruciate ligament reconstruction using a retrograde reaming technique.

Methods: Six complete knee sawbone specimens were used to ream anterior and posterior cruciate ligament sockets in the femur and tibia in a retrograde fashion using a standard retrograde reaming device. The longest and shortest sides of the sockets were measured using a ruler.
