Editorial at: “Passive anterior tibial subluxation in the setting of anterior cruciate ligament injuries: a comparative analysis of ligament-deficient states” published at AJSM by McDonald et al.

McDonald et al. (1), identified patients treated for anterior cruciate ligament (ACL) injury from their institutional registry. Measurements to determine anterior tibial translation were performed, as described and validated by Iwaki et al. (2,3), determining the subluxation in the medial and lateral compartments.
