Medial knee displacement was the outcome considered during the landing phase of the single\u2010leg drop jumps. For both drop jump tasks, neuromuscular recruitment was evaluated through rectified normalized electromyographic activity of the quadriceps and hamstrings (amplitude and latency), and quadriceps\/hamstrings electromyographic co\u2010contraction ratio.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Although the SG\u2010ACLr group demonstrated a tendency toward a greater dynamic knee valgus during both drop jumps, these differences did not reach statistical significance.

Rehabilitation specialists need to be aware of existing kinematic and neuromuscular deficiencies years after SG\u2010ACLr.
