CONTEXT There exists controversy on the ability of a single or double anterior cruciate ligament graft technique to restore anterior cruciate ligament function. This article examines the published experimental and clinical data supporting these surgical procedures in the ability to restore knee stability. EVIDENCE ACQUISITION An analysis of anterior cruciate ligament function and single- and ...

We measured motion limits in human cadaveric knees before and after sectioning the anterior cruciate ligament and the medial structures. Sectioning the medial collateral ligament in an anterior cruciate ligament-deficient knee increased the anterior translation limit at 90 degrees of flexion but not at 30 degrees of flexion. The tibia displaced straight anteriorly without exhibiting the coupled...

Accurate reproduction of the anatomy of the anterior cruciate ligament during reconstructive surgery is paramount for obtaining good functional results. Graft size and length are important components of the reconstruction and the references we have used are Western figures. We feel that these Western figures do not apply to our local population. We performed an anthropometric study to test the ...

OBJECTIVE To determine how chronic anterior cruciate ligament deficient and surgically repaired subjects react to unexpected forward perturbations during gait as compared to healthy controls. DESIGN Gait testing of 10 chronic anterior cruciate ligament deficient subjects prior to and three months following reconstructive surgery, and 10 uninjured controls. BACKGROUND The ability of an anter...

Estrogen has been implicated as a causal factor for anterior cruciate ligament injuries in women. Studies have demonstrated a decrease in anterior cruciate ligament fibroblast proliferation and collagen synthesis at supraphysiologic levels of estrogen in a rabbit model. Hypothesis: The authors hypothesized that physiologic levels of estrogen would have no significant effect on anterior cruciate...

INTRODUCTION Diagnosis and treatment of multiple ligament injuries of the knee remain a real challenge for most surgeons. OBJECTIVE To find out the epidemiological profile of patients surgically treated at a Reference Service with more than one chronic ligament injury in the knee joint. MATERIALS AND METHODS Of a total of 978 operated patients, 109 presented at least two associated ligament...

  Background: Patients with an anterior cruciate ligament-deficient varus-angulated knee may need not only an isolated high tibial osteotomy (HTO), but also an additional anterior cruciate ligament reconstruction (ACLR). A number of prospective clinical trials have been published considering the combination of HTO and ACL reconstruction. Our aim was to investigate whether one-stage combined HTO...

The simultaneous diagnosis of ipsilateral patellar tendon rupture and anterior cruciate ligament tear is rare. Surgical repair is complicated by different rehabilitation regimens as well as anterior cruciate ligament graft choices. We present a case where at the same operative setting, the patellar tendon was repaired, and the anterior cruciate ligament reconstructed with autologous hamstring g...

BACKGROUND Female athletes have a higher incidence of anterior cruciate ligament injuries than do male athletes in similar sports. Hormones, particularly estrogen, have been indicated by some studies to be correlated with the disproportionate number of anterior cruciate ligament injuries in female athletes. HYPOTHESIS Estrogen does not affect the mechanical or material properties of primate a...
