A NEW TOOL TO OBJECTIVE ASSESSMENT OF ROTATIONAL INSTABILITY AND ACL/PCL DEFICIENT KNEES INSIDE MAGNETIC 

RESONANCE IMAGING OR CT-SCAN.

This method proved to be reliable in assessment of anteroposterior translation (comparing to KT-1000) and rotatory instability (compared to lateral pivot shift under anaesthesia) of the ACL deficient knee.

It allows a precise measurement of translation and rotation between bony land marks.

This device can be useful in the identification of patients with ACL rupture that require surgery or are advised to do conservative treatment.

It might play a role in surgical indication and prevention or identifying

partial ruptures due to its unique feature of combining anatomical and dynamic "clinical" evaluation amplified through the "eyes" of MRI or CT-scan.

This device can contribute to the decision of doing a partial repair and on the surgical technique choice (one bundle or two bundles reconstruction).
 
PKTD® can also be useful in the evaluation of knee stability after ligament reconstruction (results, return to sports activities and prevention of osteoarthritis).
