PURPOSE To systematically review and compare biomechanical results of lateral extra-articular tenodesis (LET) procedures. METHODS A systematic review was performed using the PubMed, Medline, Embase, and Cochrane databases. The search terms included the following: extraarticular, anterolateral, iliotibial, tenodesis, plasty, augmentation, procedure, reconstruction, technique, biomechanics, kin...

BACKGROUND Knee valgus load during sports movement is viewed as an important predictor of non-contact anterior cruciate ligament injury risk, particularly in females. Formulating movement strategies that can reduce valgus loading during these movements therefore appears pertinent to reducing anterior cruciate ligament injury rates. With this in mind, the current study examined the relationship ...

Small knee flexion angles at initial contact and large ground reaction forces during landing have been identified as risk factors for non-contact anterior cruciate ligament injuries that are common in sports. This study investigated the effects of knee extension constraint on knee flexion angle and ground reaction forces for patients who were 4-6 months post ACL reconstruction surgery, and also...

Background: Many factors affect the outcomes of anterior cruciate ligament (ACL) reconstruction surgery. However, few studies have examined effects local bone conditions on ACL. This study investigated changes in mineral density (BMD) knee after rupture ACL with view using this information to guide treatment options.

BACKGROUND The best choice of graft tissue for use in anterior cruciate ligament reconstruction has been the subject of debate. HYPOTHESIS Anterior cruciate ligament reconstruction with patellar tendon autograft leads to greater knee stability than reconstruction with hamstring tendon autograft. STUDY DESIGN Metaanalysis. METHODS A Medline search identified articles published from January...

A 35-year-old man was seen with pain in the back of the knee. MRI showed a mass in the anterior cruciate ligament. Biopsy indicated mucoid degeneration. Arthroscopic resection of the ligament was carried out, with relief of symptoms.

CONTEXT A ganglion is a cystic formation close to joints or tendinous sheaths, frequently found in the wrist, foot or knee. Intra-articular ganglia of the knee are rare, and most of them are located in the anterior cruciate ligament. The clinical picture for these ganglia comprises pain and movement restrictions in the knee, causing significant impairment to the patient. Symptoms are non-specif...

BACKGROUND There is controversy regarding the necessity of reconstructing both the posterolateral and anteromedial bundles of the anterior cruciate ligament. HYPOTHESIS A laterally oriented transtibial drilled femoral tunnel replaces portions of the femoral footprints of the anteromedial and posterolateral bundles of the anterior cruciate ligament. STUDY DESIGN Descriptive laboratory study....

BACKGROUND Increased knee pain at the time of anterior cruciate ligament reconstruction may potentially predict more difficult rehabilitation, prolonged recovery, and/or be predictive of increased knee pain at 2 years. HYPOTHESIS A bone bruise and/or other preoperative factors are associated with more knee pain/symptoms at the time of index anterior cruciate ligament reconstruction, and the p...

BACKGROUND There are many different materials used for ligament reconstruction. Currently, autograft, allograft, and artificial ligaments are used in the reconstruction. The objective of this study was to explore the clinical result of cruciate ligament reconstruction under arthroscopy. METHODS Eighty-one cases were reconstructed with the LARS ligament under arthroscopy, including 43 cases of...
