The effect of transtibial and transportal techniques of graft positioning on strength and proprioception in subjects submitted to anterior cruciate ligament reconstruction surgery

Objective: Investigate the effect of ACL reconstruction surgery on proprioception and muscle strength, by comparing transtibial and transporal techniques in the pre and postoperative periods of 3, 6 and 12 months. Hypothesis was that transportal technique would present better results since it provides greater anteroposterior and rotational stability. Methods: 100 patients with ACL injury, divided in Transtibial Group and Transportal Group. Evaluations were performed through Joint Position Sense, Isokinetic Test, International Knee Documentation Committee (IKDC) and Tegner Lysholm Knee Scoring Scale. Patients were assessed at 3,6 and 12 months after surgical procedure.
