Assessment of Knee Instability in ACL-Injured Knees Using Weight Bearing Computer Tomography

CurveBeam AI

Key Points: Anterior tibial translation (ATT) and femorotibial rotation (FTR) are the two most common indicators of an anterior cruciate ligament (ACL) tear. The effects of weight bearing have proven to increase the sensitivity to ATT in ACL-inured knees and to improve evaluation of femorotibial rotation. Researchers have proposed a protocol to quantitatively assess instability in ACL-injured knees using weight Bearing CT (WBCT), measuring ATT and FTR in various knee positions.
