The anterior cruciate ligament (ACL), a major stabilizer of the knee, is commonly injured. Because of its intrinsic poor healing ability, a torn ACL is usually reconstructed by a graft. We developed a multi-phasic, or bone-ligament-bone, tissue-engineered construct for ACL grafts using bone marrow stromal cells and sheep as a model system. After 6 months in vivo, the constructs increased in cro...

Since the rediscovery of anterolateral ligament, extra-articular augmentation (EA) has evolved from controversial to an essential consideration in contemporary anterior cruciate ligament reconstruction surgery. Anterolateral (ALL) and lateral tenodesis are 2 common methods. Indications among early adopters pioneering at surgery included revision (ACL) case, chronic ACL tear, high-grade pivot sh...

PURPOSE The purpose of this study was to compare the morphologic change of the posterior cruciate ligament (PCL) on magnetic resonance imaging (MRI) in chronic anterior cruciate ligament (ACL) tear before and after reconstruction. MATERIALS AND METHODS On the MRI image after ACL reconstruction, a base line (BL) was drawn between the femoral and tibial insertion sites of the PCL. Point A was e...

Introduction Bone-patella tendon-bone (BPTB) grafts are widely used for anterior cruciate ligament (ACL) reconstruction. Experimental data have demonstrated that these grafts are almost 3 times stiffer than the ACL. (1,2) While many in-vivo and in-vitro data demonstrated that the ACL reconstruction is efficient in restoring anterior stability using anterior drawer tests, recent in-vivo measurem...

Anterior cruciate ligament (ACL) injury is common in knee joint accounting for 40% of sports injury. ACL injury leads to knee instability, therefore, understanding knee stability assessments would be useful for diagnosis of ACL injury, comparison between operation treatments and establishing return-to-sport standard. This article firstly introduces a management model for ACL injury and the cont...

Background: Anterior cruciate ligament (ACL) reconstruction using tendon or ligament autograft is the current goldstandard surgical technique for acute ACL ruptures. However, ACL repair surgical procedures are reappearing as anoptimistic treatment alternative for acute proximal ruptures. The purpose of this annotation is to review the current roleof primary repair of the ACL.<...

The graft choice for anterior cruciate ligament (ACL) reconstruction continues to be controversial. There are several options available for the treating surgeon, including Bone Patellar Tendon Bone (BPTB) grafts, Hamstring tendon (HT) grafts, allografts and synthetic grafts. Within the last decade there have been several comparative trials and meta-analysis, which have failed to provide an answ...

Anterior cruciate ligament (ACL) tears are commonly seen injuries. Initially, these injuries are routinely evaluated with radiographs, followed by magnetic resonance imaging (MRI). The altered kinematics at the time of injury or for the duration of a chronic tear can create indirect findings on radiographs and MRI. These signs may help establish a diagnosis of an ACL tear or the chronicity of t...

Increased stability has been reported with both autografts and allografts for anterior cruciate ligament (ACL) reconstruction. However, meta-analysis has shown significantly lower overall knee stability rates and more than double the abnormal stability rate with allografts. Some issues surrounding allograft sterilization (ie, risk of disease transmission) are unresolved, and cost is also a conc...

We report the case of a 16-year-old woman who experienced failure of her bone-patellar tendon-bone (BPTB) reconstruction of her left anterior cruciate ligament (ACL) due to detachment of the femoral bone plug from the endobutton. We have only found one prior report of this unusual complication. This case is also notable in that evidence of this complication is visible radiographically. Most pos...
