Biologic Approaches for the Treatment of Partial Tears of the Anterior Cruciate Ligament
The anterior cruciate ligament (ACL) is one of the most studied structures of the human musculoskeletal system, being the subject of many anatomic and biomechanical studies. While treatment options for complete ruptures of the ACL are well studied, partial ACL tears [...]
Overlap Between Anterior Cruciate Ligament and Anterolateral Meniscal Root Insertions
AJSM 2016 Over the past decade, there has been an increasing emphasis on anatomic anterior cruciate ligament (ACL) reconstruction to best restore knee kinematics after an ACL tear. Although studies have shown that the position, size and shape of the [...]
Posterior Wall Blowout During Anterior Cruciate Ligament Reconstruction: Suspensory Cortical Fixation With a Screw and Washer Post
2016 Arthroscopy Posterior wall blowout can be a devastating intraoperative complication in anterior cruciate ligament reconstruction. This loss of osseous containment can cause difficulty with graft fixation and can potentially lead to early graft failure if unrecognized and left untreated. [...]
Posterior Wall Blowout in Anterior Cruciate Ligament Reconstruction
OJSM 2016 Violation of the posterior femoral cortex, commonly referred to as posterior wall blowout, can be a devastating intraoperative complication in anterior cruciate ligament (ACL) reconstruction and lead to loss of graft fixation or early graft failure. If cortical [...]
Outcomes and Risk Factors of Rerevision Anterior Cruciate Ligament Reconstruction: A Systematic Review
ARTHROSCOPY 2016 Purpose: The purpose of this study was to systematically review the literature on rerevision anterior cruciate ligament (ACL) reconstruction, focusing on patient outcomes. The secondary aims of this study were to (1) identify risk factors that contribute to [...]
High-Load Preconditioning of Soft Tissue Grafts: An In Vitro Biomechanical Bovine Tendon Model
2016 KSSTA No consensus exists regarding the optimal preconditioning protocol that will minimize postoperative elongation while creating a graft that is biomechanically equivalent to the native anterior cruciate ligament (ACL). It was hypothesized that a preconditioning protocol of specific mode [...]
Lack of consensus regarding pretensioning and preconditioning protocols for soft tissue graft reconstruction of the anterior cruciate ligament
KSSTA 2015 Pretensioning and preconditioning of soft tissue grafts are often performed to obviate graft stress relaxation and elongation due to viscoelastic graft properties following anterior cruciate ligament (ACL) reconstruction. It was hypothesized that a consensus could be identified in the [...]
Dimensional assessment of continuous loop cortical suspension devices and clinical implications for intraoperative button flipping and intratunnel graft length
JOURNAL OF ORTHOPAEDIC RESEARCH 2015 Continuous loop cortical suspension devices have been demonstrated to be more consistent and biomechanically superior compared to adjustable loop devices; however, continuous loop devices present unique challenges compared to adjustable loop devices, especially in short [...]
Return to Play Following Anterior Cruciate Ligament Reconstruction
AAOS 2015 In athletes, significant advances in anterior cruciate ligament reconstruction techniques and rehabilitation have led to improved surgical outcomes and increased expectations for return to play. Although an expeditious return to sport has become an achievable and often realistic [...]
Functional bracing of ACL injuries: current state and future directions
KSSTA 2013 Functional braces are commonly prescribed to treat anterior cruciate ligament (ACL) injury. The results of the existing literature on functional brace use are mixed. The purpose of this study was to evaluate the history and current state of functional [...]
Femoral Cortical Suspension Devices for Soft Tissue Anterior Cruciate Ligament Reconstruction
AJSM 2013 Optimization of anterior cruciate ligament (ACL) fixation is desired to improve graft healing. New soft tissue cortical suspension devices for femoral tunnel fixation should be biomechanically evaluated. This study hypothesized that all femoral fixation devices would prevent a [...]
Biomechanical Comparison of Interference Screws and Combination Screw and Sheath Devices for Soft Tissue Anterior Cruciate Ligament Reconstruction on the Tibial Side
AJSM 2013 The tibial fixation site has been reported to be the weakest point in anterior cruciate ligament (ACL) reconstructions. Numerous interference screws and combination screw and sheath devices are available for soft tissue fixation, and a biomechanical comparison of [...]
Biomechanical Comparison of Anatomic Single- and Double-Bundle Anterior Cruciate Ligament Reconstructions
AJSM 2013 Arthroscopic identification of the anteromedial (AM) and posterolateral (PL) bundle locations of the anterior cruciate ligament (ACL) has facilitated an improved quantitative description of ACL anatomy. Few studies have directly compared the biomechanical laxity of anatomic single-bundle (SB) [...]
Evaluation of a Simulated Pivot Shift Test
KSSTA 2011 Double-bundle anterior cruciate reconstructions have led to an increased interest in quantifying anterolateral rotatory stability. The application of combined internal rotation and valgus torques to the knee can more nearly recreate the anterolateral subluxation that occurs in the pivot [...]
