Objective: Double-bundle and selective-bundle anterior cruciate ligament (ACL) reconstructions are increasingly performed to better reproduce the double-bundle anatomy of the native ACL and to improve knee stability and surgical outcomes. This article illustrates how to optimize visualization of the ACL bundle anatomy and the appearances of graft components and postoperative complications.
Conclusion: It is important for the radiologist to be familiar with the appearance of double-bundle and selective-bundle ACL reconstructions and associated complications.

Purpose: To evaluate the optimal graft tension angles in a medial patellofemoral ligament (MPFL) reconstruction with selective bundle tensioning in order to restore patellofemoral contact pressure distributions closest to the native state.
Methods: Twelve human cadaveric knee specimens were mounted with the femur on a custom-made fixation device allowing free range of motion in the knee joint for testing. Using a sensitive pressure film (Tekscan) patellofemoral contact pressure was measured in 15° intervals during a dynamic flexion movement from 0°-90° in the native state, in cut MPFL and after MPFL-reconstruction with a gracilis tendon.

Purpose: Reconstruction of the anterior cruciate ligament (ACL) is the most frequently performed reconstructive surgery in the knee. Biomechanical studies have shown that double bundle (DB) reconstruction is better than single bundle (SB) reconstruction with regard to rotational stability. It is postulated that resection of ACL fibres that remain in continuity may be counterproductive for the knee as these fibres have the capacity to produce collagen.

Purpose: The purpose of this study was to compare the clinical outcomes of arthroscopic anatomical double bundle (DB) anterior cruciate ligament (ACL) reconstruction with either selective anteromedial (AM) or posterolateral (PL) bundle reconstruction while preserving a relatively healthy ACL bundle.
Materials And Methods: The authors evaluated 98 patients with a mean follow-up of 30.8±4.

Background: The use of double-bundle and selective-bundle anterior cruciate ligament (ACL) reconstruction is increasing. Few studies have been conducted to determine the diagnostic efficacy of additional oblique views of knee magnetic resonance imaging (MRI) for grading ACL graft injury for double-bundle and selective-bundle ACL reconstructions.
Purpose: To evaluate the diagnostic value of combining oblique coronal and sagittal imaging with orthogonal views for diagnosis of ACL graft failure after double-bundle or selective-bundle ACL reconstruction.

Purpose: The objective of this study was to compare the clinical and radiologic results of preserved ligament remnants in the selective bundle anterior cruciate ligament (ACL) reconstruction and totally sacrificed ligament remnant in the double-bundle ACL reconstruction in order to confirm the evidence of selective bundle reconstruction.
Methods: This retrospective comparative study was conducted for comparison between preserved ligament remnants in the selective bundle ACL reconstruction and totally sacrificed ligament remnant in the double-bundle ACL reconstruction. From 2008 to 2010, 16 patients (group I) underwent selective bundle ACL reconstruction and 30 patients (group II) underwent double-bundle ACL reconstruction.
