Comparison between a Novel Knee Arthrometer and Simultaneous Stress Radiography for the Diagnosis of Complete and Partial Acute Anterior Cruciate Ligament Tears.

Compared with single instrumental measurement, the combination of the two measurements can further improve the diagnostic value in this regard.
