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 ACL insertion site are variable, anatomic single-and double-bundle ACL reconstructions […]
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 remain more nebulous in their postinjury treatment course. Partial ACL tears were first described […]
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 blowout occurs despite careful planning and adherence to proper surgical technique, a thorough knowledge of […]
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 multiple ACL reconstruction failures (defined as a complete tear of a revision ACL graft with […]
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. If cortical blowout occurs despite careful planning and proper surgical […]
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 and magnitude would create a graft with equivalent stiffness to the native ACL.
In this experimental […]
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 current literature regarding the biomechanical effects and clinical benefits of an optimal protocol. This study found […]
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 tunnel reconstruction applications. Specifically, adjustable loop devices have the a the intratunnel graft length to be […]
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 goal, the factors that most influence safe, timely, and successful return to play remain unknown. The […]
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 ACL bracing and to identify design criteria that could improve upon current bracing technologies.
