✅ Differentiating Revascularization from Graft Tear

•  Secondary indicators of graft rupture include uncovering the lateral meniscus's posterior horn, visualization of the complete lateral collateral ligament in one coronal slice, buckling of PCL, and anterior translation of the tibia. 
• The observation of secondary signs is crucial in distinguishing between graft tears and the normal revascularization process of the graft, which might present a similar appearance on imaging.
• Clinical Signs of Instability: These, rather than a decreased range of motion, and a history of re-injury, are critical factors in differentiating a rupture from impingement or the subacute stage of ligamentization in challenging cases.
