Measuring Knee Laxity

The Blue Bay KA is designed to measure the anterior-posterior placement of the tibia relative to the patella.  This is to aid in diagnosis of knee cruciate ligament injuries (ACL and PCL).  The KA is indicated for use in providing a quantitative assessment of knee laxity in anterior-posterior loading.
