The association of extra-articular tenodesis restores rotational stability more effectively compared to contralateral hamstring tendon autografts ACL reconstruction alone in patients undergoing ACL revision surgery.

摘要: Abstract Background Recent years have seen a resurgence of interest about lateral extra-articular procedures performed in association with anterior cruciate ligament (ACL) surgery, as they can reduce the positivity to pivot shift test by acting on rotational instability. The purpose present study is compare postoperative functional outcomes ACL revision surgery using contralateral hamstring tendon autografts or without tenodesis. Hypothesis hypothesis that combined tenodesis gives better stability following surgery. Patients and methods Twenty-four patients who underwent were retrospectively reviewed at an average follow-up 4.5 years; 12 reconstruction (group A) while was associated B). Assessment included Lysholm score, International Knee Documentation Committee (IKDC) Subjective Form, Tegner activity level objective evaluation (range motion, Lachman test, pivot-shift KT-1000 instrumented laxity testing). Results Follow-up examination showed there no statistically significant differences Lysholm, IKDC scores between groups (p = n.s.). Similarly, concerning tibial translation measured arthrometer reported (p = n.s.); percentage significantly higher group A (p  Conclusions restores more effectively compared alone. Level evidence III.
