Recently I spoke with the most experienced US user of our GNRB ACL robotic arthrometer. He has used the device for over a year now.

A few points based on my notes may interest clinicians considering prescribing or performing GNRB tests.

– Pre-surgical use for tear detection.

– Reliability and reproducibility are the big differences relative to the KT : “take out the human element.”

– One very active referring surgeon looks at measures 3 weeks post-op ; then 16 ; then 24.

– Slow down rehab if GNRB indicates unusual looseness.

– Device used for return to play.

– Tests reimbursed; “pays for itself.”
