the aim of this study is to compare three modes of femoral fixation, namely aperfix, rigidfix and endobutton, in anterior cruciate ligament (acl) reconstruction. 120 patients were randomly assigned to three groups, each consisting of 40 patients, and each group was treated by one of the above mentioned methods of femoral fixation. all patients were examined prior to and 24 months after surgery,...

Anterior cruciate ligament injury is a debilitating pathology which may alter lower limb coordination pattern in both intact and affected lower extremities during activities of daily living. Emerging evidence supports the notion that kinematic variables may not be a good indicator to differentiate patients with anterior cruciate ligament deficiency during step descent task. The aim of the prese...

BACKGROUND Functional exercises are important in the rehabilitation of anterior cruciate ligament deficient and reconstructed individuals but movement compensations and incomplete recovery persist. This study aimed to identify how tasks pose different challenges; and evaluate if different activities challenge patient groups differently compared to controls. METHODS Motion and force data were ...

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...

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...

BACKGROUND Recently backward walking is used by physical therapists to strengthen the hamstring muscles and thus improve the function of the knee joint of anterior cruciate ligament deficient patients. The aim of this study was to examine the stride-to-stride variability of anterior cruciate ligament deficient patients during backward walking. The variation of how a motor behavior emerges in ti...

BACKGROUND Articulated external fixation has been proposed as a method to protect ligament reconstructions while allowing aggressive and early postoperative rehabilitation after knee dislocation. However, the ability of these fixators to protect and stabilize the knee joint has not been clearly determined. HYPOTHESIS Articulated external fixation can reduce anteroposterior translation in the ...

Meniscal injury has been well documented in association with injury to the anterior cruciate ligament. The purpose of this study was to evaluate the effect of anterior cruciate ligament transection and reconstruction on meniscal strain. Four differential variable reluctance transducer strain gauges were placed in the medial and lateral menisci of nine cadaveric knees. Each specimen was mounted ...

dear editor,we have greatly enjoyed reading the case report entitled “‘femoral condyle fracture during revision of anterior cruciate ligament reconstruction: case report and a review of literature in the issue of arch bone jt surg. 2015;3(2) with great interest. we would like to commend the authors for their detailed and valuable work. although various case reports have described postoperative ...

anterior cruciate ligament (acl) reconstruction surgery has significantly evolved in recent years. this has led to development of new technologies that facilitate the diagnosis of acl injury and the application of state of the art methods for treatment. in particular, individualized anatomical acl reconstruction aims to restore native acl function. treatment is tailored to each patient based on...
