We developed a biomechanical model to determine the joint torques and loadings during squatting with a backward/forward-inclined Smith machine. The Smith squat allows a large variety of body positioning (trunk tilt, foot placement, combinations of joint angles) and easy control of weight distribution between forefoot and heel. These distinctive aspects of the exercise can be managed concurrentl...

INTRODUCTION The Segond injury corresponds to a marginal avulsion fracture of lateral tibial plateau, resultant from flexion traumas, stress in varus and internal rotation. The structure responsible for avulsion is the lateral collateral ligament, and anterior cruciate ligament and lateral meniscal injuries are also frequently present(1-4). Hall and Hochman(5) provided the first report of an in...

Posterior cruciate ligament (PCL) injuries associated with multiple ligament injuries can be easily diagnosed, but isolated PCL tears are less symptomatic, very difficult to diagnose, and frequently misdiagnosed. If a detailed investigation of the history of illness suggests a PCL injury, careful physical examinations including the posterior drawer test, dial test, varus and valgus test should ...

One should suspect a compromise of the lateral structures when presented with a posterior cruciate ligament (PCL) injury, especially if grade III laxity is present. In our experience, if a combined injury to the PCL and posterolateral corner is diagnosed, a combined PCL and posterolateral reconstruction is needed to restore stability. This article describes a posterolateral reconstruction proce...

Meniscal injury has been well documented in association with injury to the anterior cruciate ligament. The purpose of this study was to evaluate the effect of anterior cruciate ligament transection and reconstruction on meniscal strain. Four differential variable reluctance transducer strain gauges were placed in the medial and lateral menisci of nine cadaveric knees. Each specimen was mounted ...

INTRODUCTION Bucket handle tear of the menisci is a common type of lesion resulting from injury to the knee joint. Bucket handle injury of both menisci in almost all cases is associated with a lesion to either the anterior or the posterior cruciate ligament of the knee joint. We describe a case of acute bucket-handle tear of the medial and lateral menisci with intact anterior and posterior cruc...

BACKGROUND Following anterior cruciate ligament injury and subsequent reconstruction transverse plane tibiofemoral rotation becomes underconstrained and overconstrained, respectively. Conflicting reports exist on how rotations influence loading at the knee. This investigation aimed to determine the mechanical effects of internal and external tibial rotation offsets on knee kinematics and ligame...

After surgical anterior cruciate ligament (ACL) reconstruction, knee bracing does not significantly protect against injury during recovery or afterwards (strength of recommendation [SOR]: C, based on expert opinion). In addition, the use of a knee brace following ACL reconstruction does not improve stability or hasten rehabilitation, either immediately or for up to 2 years (SOR: A, based on ran...

Background: Some reports showed, no clear difference in treatment outcome between the single-bundle and double-bundle reconstruction techniques for posterior cruciate ligament (PCL) injury. Using patientbased QOL evaluation scale SF-36, we evaluated postoperative compared two techniques.
