Crusiate Ligaments Sprain - Essay ExampleHowever, in complex sprains a large segment of the fibres are torn and the ends of the ligament may have separated from each other. This would result in immense pain as salubrious as instableness of the joint and it may require operative treatment. Rouzier indicates that sprains may be graded according to their severityAccording to the Chester human knee Clinic, the genu is a well exposed structure that consists of two joints and made up of three bones namely, the femur, tibia and the patella. They further go on to describe its anatomy in greater detailThe tibio-femoral joint has mesial and lateral compartments. The medial and lateral femoral condyles articulate with the medial and lateral tibial plateaus. The patella covers the front of the knee. The patello-femoral joint is the spliff of the patella with the femoral trochlea. All joint surfaces are covered with hyaline articular cartilage.This anatomy of the knee joint offers no real s upport to the joints stability. Thus, ligaments are essential in regulating the movement of the knee joint and maintaining its stability. Various stabilizing configurations are brought into play as the knee moves through its full blow of motion, giving dynamic stability to the joint (Smith and Moran 1).Avery describes the knee joint as consisting of four essential ligaments that embolden in its stabilization. The sides of the joint consist of the medial and lateral collateral ligaments which aid in the side-to-side stability of the joint. In the front of the joint is the anterior crusiate ligament (ACL) which serves to prevent the tibia from sliding forward and rotating during various active activities such as jumping. Opposite to the ACL is the posterior crusiate ligament (PCL) which prevents the tibia from sliding back. The crusiate ligaments regulate movement as the focus of rotation changes during movement. The presence of the menisci is another important feature for not onl y do they act as shock absorbers, but they also aid in weight distribution (ehealthMD 1). Incidentally, the crossing of the ACL and PCL in the marrow squash of the knee is what gives rise to the term crusiate. Representations of these structures courtesy of the Journal of the American Medical Association are as seen in Figures 1 and 2 below.Figure 1 Anatomy of the Right KneeFigure 2 Anatomy of the right knee with ligaments cut.Knee BiomechanicsAs Elliot explains, clinical biomechanics refers to the research conducted on the actions of walking, tissue mechanics, neuromuscular control and the evaluation of movement when an individual is undergoing rehabilitation when recovering from disease or injury (1).The Chester Knee Clinic provides a comprehensive understanding of the biomechanics of the knee. The bones of the knee joint, unlike the hip joint, are not a close fit to one another. This variation allows for a wider range of motion to occur in enact for an individual to carry out d aily activities. However, this range of motion is still limited in its contagious stability due to the bony structure of the joint. According to the KneeDoc, the lack
