BACKGROUND Noncontact anterior cruciate ligament injuries occur two to eight times more often in women than in men. Changes in ligament laxity and strength have been associated with female hormones such as relaxin. HYPOTHESIS Relaxin receptors are present within the female anterior cruciate ligament. STUDY DESIGN Controlled laboratory study. METHODS Remnants of anterior cruciate ligament ...

Anterior cruciate ligament reconstruction (ACLR) is an accepted and established surgical technique for anterior cruciate ligament (ACL) injuries and is now being practiced across the globe in increasing numbers. Although most patients get good to excellent results in the short-term after ACLR, its consequences in the long-term in prevention or acceleration of knee osteoarthritis (OA) are not ye...

BACKGROUND Despite increasing attention on fixation of a soft tissue anterior cruciate ligament graft in the tibia, there have been no studies on the use of a bone dowel as a joint line fixation device for promoting fixation properties, especially stiffness at the time of implantation. PURPOSE To determine whether compacting a bone dowel into the tibial tunnel improves fixation stiffness, yie...

Posterior wall blowout is an important potential source of anterior cruciate ligament reconstruction failures that can be avoided if surgeons adhere to proper technique and are vigilant in confirming appropriate femoral tunnel placement. This article reviews techniques for avoidance, recognition, and salvage of posterior wall blowouts in anterior cruciate ligament reconstruction surgery.

INTRODUCTION Anterior cruciate ligament rupture is a common injury in sports practice. It can be associated to many other injuries; the most frequent ones include meniscal and chondral injuries. Those injuries may be acute as a result of trauma, or chronic as a result of instability occasioned by anterior cruciate ligament injuries(1). Menisci play an important functional role in the knee, beca...

BACKGROUND While single-bundle anterior cruciate ligament reconstruction reduces anterior-posterior laxity, studies have demonstrated residual rotational instability. Improved pivot-shift results have been shown with the double-bundle graft; however, no study has compared rotational laxity outcome of these surgical techniques in vivo under quantified, isolated torsional loading. HYPOTHESIS Th...
