Multiple ligament knee injuries, although rare, are severe injuries that often result in the loss of the passive and active knee stabilizers as well as often being associated with the compromise of neurovascular structures. Treatment of these injuries is controversial, and results after surgery are often poor. After sustaining injuries to multiple ligaments, the knee is at a biomechanical disad...

Femoral tunnel intersection in combined anterior cruciate ligament and posterolateral corner reconstruction has been reported to be high. The purpose of this study was to examine the risk of intersection between an anatomic femoral anterior cruciate ligament tunnel created with a retrograde reaming device and femoral lateral collateral ligament reconstruction tunnels of varying trajectory in a ...

Posterior wall blowout is an important potential source of anterior cruciate ligament reconstruction failures that can be avoided if surgeons adhere to proper technique and are vigilant in confirming appropriate femoral tunnel placement. This article reviews techniques for avoidance, recognition, and salvage of posterior wall blowouts in anterior cruciate ligament reconstruction surgery.

BACKGROUND While single-bundle anterior cruciate ligament reconstruction reduces anterior-posterior laxity, studies have demonstrated residual rotational instability. Improved pivot-shift results have been shown with the double-bundle graft; however, no study has compared rotational laxity outcome of these surgical techniques in vivo under quantified, isolated torsional loading. HYPOTHESIS Th...

OBJECTIVE To test an intra-articular reconstruction of the anterior cruciate ligament of the knee in 10 human cadavers by replacing 2 anterior cruciate ligament bundles, with the purpose of producing a surrogate that would be structurally more similar to the anatomy of the anterior cruciate ligament and would provide the knee with more stability. METHODS We reconstructed the anteromedial and ...

The purpose of this study was to examine the establishment of a model concerned with osteoarthritis resulting from the anterior cruciate ligament rupture of rats and investigate the associated mechanism, as well as provide a theoretical basis for clinical treatment of the disease. Forty Sprague-Dawley male rats were randomly divided into two groups of 20 rats each and the anterior cruciate liga...

BACKGROUND Female athletes suffer a greater incidence of anterior cruciate ligament tears compared with male athletes when participating in common sports; however, very little is known about the factors that explain this disparity. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Female recreational alpine skiers with an anterior cruciate ligament rupture and age-matched contr...

background: daily increased rate of anterior cruciate ligament (acl) injuries in athletes calls for more investigation in these patients to differentiate copers from noncoper acl-deficient (acld) knees as soon as possible. objectives: the current study aims to introduce a new electromyographic protocol, named voluntary response index (vri), that might help to categorize and differentiate patien...

abstract background and aim: lack of balance in pattern and activity of quadriceps and hamstring muscles increases the risk of anterior cruciate ligament injury (acl). the purpose of the present study was to investigate the changes in pattern and activity of vastus medialis and semitendinosusmuscles in landing from different heights and to understand if these changes will increase the risk of a...

BACKGROUND Currently, a suitable and reliable noninvasive method to evaluate rotational stability in vivo in anterior cruciate ligament-deficient knees, particularly during sports movements, does not exist. We speculated that if there is a rotational instability, the patient would avoid reaching a high pivoting moment during pivoting activities as a defense mechanism, and that the ground reacti...
