After his dramatic turn in "The Debt", does Sam Worthington pull off another credible performance in another quality film? Hello there to everyone and welcome back to ReelScreenReviews.com, I am movie critic Nick Iacobucci and our next movie review is "Man on a Ledge". This thriller opened in wide release on Friday January 27th, 2012, and it stars Sam Worthington, Elizabeth Banks, Jamie Bell, Kyra Sedgwick, and Ed Harris. "Man on a Ledge" comes to us from director Asger Leth, a previous documentary filmmaker that now takes a crack at a mainstream action and thrill ride.
Our tale tells of former cop Nick Cassidy that is now on the opposite end of the law. Nick is portrayed by Sam Worthington and is an ex-con that gains the attention of an entire city when he steps out onto the ledge of a high rise tower. Within a short amount time we soon have the fire department, law enforcement agencies, and many news vans broadcasting the drama live for all to see. We also see the addition of a trained police psychologist to try and talk down the man obviously at wits end by stepping onto the brink of death. Or is this the result of a very complex and intricate plot that has set up our lead character from the beginning?

The two menisci are crucial to the stability of the knee during movement, and to the durability of the knee over time. Tears in a meniscus will decrease the knee's stability and increase the wear of the articular cartilage. Tears can occur because of degenerative stiffening with aging, or through abnormal isolated or repetitive movements such as due to an acute or chronic ligament tear. Meniscal tears can also occur due to an abnormally shaped or attached meniscus that doesn't move or distribute forces effectively.

Meniscal tears can be partially or completely through the meniscus, they can be single or in multiple locations, and they can have complex shapes.
Longitudinal or vertical tears occur in the periphery or substance of the meniscus. They can allow the medial flap of the meniscus to slide into the joint or they can extend and allow the flap to flip into the central part of the knee joint. This is known as a bucket handle tear.

A flap or oblique tear has a loose medial flap, and can occur as an acute tear, or as a progression of a longitudinal tear. They can also flip into the knee joint.
Vertical tears can also be radial or transverse, or have loose tags.
Horizontal or cleavage tears usually occur in the degenerate stiff meniscus.
Tears may be asymptomatic, or they may cause locking, catching, giving way, pain or swelling. The outer third of the meniscus has a blood supply, so tears in this region may heal. Tears in the inner two thirds of the meniscus don't heal, and are likely to become longer and cause worse symptoms.

Over time, meniscal tears can lead to indentation of the articular surface, with fissures and erosions of the articular cartilage. This can lead to accelerated cartilage degeneration and osteo-arthritis, especially if there are also abnormal movements due to loose or torn ligaments.
During movements of the knee, the menisci can be injured if they fail to follow the movements of the femoral condyles on the tibial condyles. They are 'caught unawares' in an abnormal position and are squashed. This can happen during violent extension of the knee, such as when kicking a ball. If one of the menisci fails to move forwards, it can be caught between the femoral and tibial condyles as the tibia is forcefully applied to the femur. This mechanism leads to transverse tears or detachment of the anterior horn which then becomes folded on itself. The other mechanism producing lesions of the menisci involves a twisting movement of the knee joint, which combines with lateral displacement and lateral rotation. The medial meniscus is then pulled towards the centre of the joint under the convexity of the medial femoral condyle. When the joint is extended, the meniscus can be crushed between the two condyles, leading to longitudinal splitting of the meniscus, a complete detachment of the meniscus from the capsule, or a complex tear of the meniscus. In all these longitudinal lesions, the central part of the meniscus can rear itself up into the intercondylar notch so that the meniscus assumes the shape of a bucket-handle. This type of lesion is very common among footballers (ie during falls on a flexed leg) and among miners who have to work crouched in narrow seams of coal.
As soon as a meniscus is torn, the injured part fails to follow the normal movements and becomes wedged between the femoral and tibial condyles. The knee as a result 'locks' in a position of flexion, which is more marked the more posterior the rupture. Full extension is then impossible.
It is unusual to see a true, fresh, isolated avulsion of a meniscus caused by a single traumatic episode. Usually this type of injury is associated with acute ligamentous disruption. Moreover, these traumatic disruptions occur at the periphery, often in the deep capsular fibers rather than in the substance of the cartilage. Nevertheless, even in the young individual twisting injuries, particularly under compression, cause mid-substance tears of a horizontal, radial (vertical), or longitudinal variety. The medial edges of these tears may dislocate into the joint. These injuries are referred to as bucket handle tears. Alternatively, small tags, from the anterior or posterior horn may ultimately become symptomatic. These injuries are called pedunculated (tag) tears or parrot beak tears.
