Background. The injured anterior cruciate ligament (ACL) has a limited healing capacity leading to persisting instability. Hypothesis/Purpose. To study if the application of a brace, producing a dynamic posterior drawer force, after acute ACL injury reduces initial instability. Study Design. Cohort study. Methods. Patients treated with the ACL-Jack brace were compared to controls treated with p...

Anterior cruciate ligament (ACL) reconstruction is a common surgical knee procedure that requires intensive postoperative rehabilitation by the patient. A variety of randomized controlled trials have investigated aspects of ACL reconstruction rehabilitation. A systematic review of English language level 1 and 2 studies identified 54 appropriate randomized controlled trials of ACL rehabilitation...

INTRODUCTION The most common cause of technical failure in anterior cruciate ligament (ACL) reconstruction is the bone tunnel misplacement(1). However it is technically challenging to place the bone tunnel in the anatomically correct position. The aim of this study was to prove the hypothesis that fluoro-based navigation system contribute to the accuracy and reproducibility of bone tunnel place...

Reconstruction of the anterior cruciate ligament (ACL) is widely accepted as the treatment of choice for individuals with functional instability due to an ACLdeficient knee. It is estimated that anywhere between 60,000 and 75,000 ACL reconstructions are performed annually in the United States, although this number may be as high as 350,000. Despite the fact that nearly 90% of index ACL reconstr...

BACKGROUND It has been recently reported that human anterior cruciate ligament (ACL) ruptured tissue contains abundant vascular stem cells that contribute to tendon-bone healing in an immunodeficient rat model of ACL reconstruction. HYPOTHESIS Autologous ruptured ACL tissue has an effect on the maturation of bone-tendon integration in anterior cruciate ligament reconstruction. STUDY DESIGN ...

BACKGROUND Reports on outcome after posterior cruciate ligament (PCL) reconstruction often contain both isolated PCL and combined knee ligament injuries. This makes it difficult to conclude on the outcome after reconstruction of isolated PCL injuries. PURPOSE To investigate the outcome after PCL reconstruction in patients with an isolated PCL injury and to compare this with the outcome of pat...

BACKGROUND Anterior cruciate ligament (ACL) reconstruction is considered as the standard surgical procedure for the treatment of ACL tear. However, there is a crucial controversy in terms of whether to use autograft or allograft in ACL reconstruction. The purpose of this meta-analysis is to compare autograft with allograft for patients undergoing ACL reconstruction. METHODS PubMed, EMBASE, an...

Anterior cruciate ligament (ACL) reconstruction restores knee stability but does not reduce the incidence of posttraumatic osteoarthritis induced by inflammatory cytokines. The aim of this research was to longitudinally measure IL-1β, IL-6, IL-8, IL-10, and TNF-α levels in patients subjected to ACL reconstruction using bone-patellar tendon-bone graft. Synovial fluid was collected within 24-72 h...

Objective: The goals of this study are to address several questions, the answers to which are key to the understanding and eventually to the prevention of this frequent source of morbidity. These questions include the following: (1) What is the natural history of anterior cruciate ligament (ACL) deficiency? (2) How important is the status of the meniscus at the time of reconstruction? (3) Does ...

BACKGROUND Anterior cruciate ligament (ACL) reconstruction is associated with a high incidence of second tears (graft tears and contralateral ACL tears). These secondary tears have been attributed to asymmetrical lower extremity mechanics. Knee bracing is one potential intervention that can be used during rehabilitation that has the potential to normalize lower extremity asymmetry; however, lit...
