Background: It has been shown that the proper placement of ACL graft during the ACL reconstruction surgery significantly improves the clinical outcomes. This study investigated whether a change in the femoral tunnel position in both axial and coronal planes can significantly alter the postoperative functional and clinical outcomes of the patients. Methods: This comparative, retrospective, singl...

BACKGROUND There is controversy regarding the necessity of reconstructing both the posterolateral and anteromedial bundles of the anterior cruciate ligament. HYPOTHESIS A laterally oriented transtibial drilled femoral tunnel replaces portions of the femoral footprints of the anteromedial and posterolateral bundles of the anterior cruciate ligament. STUDY DESIGN Descriptive laboratory study....

OBJECTIVE The objective of this study was to describe the methodology of knee rotation analysis using biomechanics laboratory instruments and to present the preliminary results from a comparative study on patients who underwent anterior cruciate ligament (ACL) reconstruction using the double-bundle technique. METHODS The protocol currently used in our laboratory was described. Three-dimension...

PURPOSE The purpose of this study was to evaluate the effect of the anatomic double-bundle reconstruction (ADBR) of the posterior cruciate ligament (PCL) with 2 femoral tunnels and 2 tibial tunnels. METHODS Eight fresh-frozen human knees were used. Bone tunnels were created based on the PCL anatomic footprints. A 9-mm looped semitendinosus and gracilis tendon for anterolateral bundle reconstr...

To determine whether untreated grade 3 posterolateral knee injuries contribute to a significant increase in force on a posterior cruciate ligament reconstruction graft, we measured the force on the graft during joint loading of a posterior cruciate ligament-reconstructed knee with otherwise intact structures and then selectively cut the popliteofibular ligament, popliteus tendon, and the fibula...

INTRODUCTION: The posterior cruciate ligament (PCL) is a complex soft tissue structure made up of several bands that play unique roles in the stability and kinematics of the knee. Most attention has been paid to the reconstruction of the anterolateral band, but the results of such reconstructions have been inconsistent1. Controversy exists over what graft tension should be used and at what flex...

OBJECTIVE The objective of this study was to evaluate the results obtained from posterior cruciate ligament (PCL) reconstruction with the double femoral tunnel technique, using quadriceps tendon and semitendinous autograft, in patients with isolated PCL tears or PCL tears associated with other ligament lesions, 2 years after surgery. METHODS The study included 14 patients with isolated PCL le...

conclusions the clinical examination is an important and accurate diagnostic modality for evaluation of traumatic derangement of the knee joint. it is noninvasive, easy, available, and valuable diagnostic modality. the mri is an accurate diagnostic modality. it can be used whenever there is an uncertain indication for arthroscopy. however, costs have to be kept in mind, especially in patients w...
