The knee joint kinematics could be seriously affected by different reasons. In most of these cases a clear isolation of the specific reason is seldom possible due to the absence of the sufficient results to consolidate the argument (Murray et al, 1985).One such case is the reason for the weakness of the muscle during the aging process. …

Uncertainty in the knee impairment assessment.

This situation often results in lowered postural stability leading to reduction in independence and higher risk of falling. The quadriceps are vital muscle group required to support all the activities for daily life (ADL). The reduction in the strength of quadriceps is required for decreased ADL performance and an increased frequency of fall in elders. Further, earlier studies have shown that the impairment of muscles could also lead to proprioceptive acuity (Aniss et al, 1990). The detailed study have been undertaken to compare the quadriceps strength, activation proprioceptive acuity, postural stability and the performance of functional activities in young, middle-aged and elderly subjects (Hurley et al, 1998). The results from this study showed revealed that proprioception and functional performance on different age groups revealed that the strength of the quadriceps was negatively correlated with the age. While all the age groups displayed identical postural stability in bipedal stance with their eyes open, both the middle and elderly age groups were unable to maintain monopedal stance at least for 15 seconds (Hurley et al, 1998). On postural stability, the monopedal stance has significant age influence over the bipedal stance. Hurlet et al (1998) have confirmed that deterioration of muscle strength, proprioceptive acuity and postural stability with the age is the prime reason for the increased duration of the ADL and adversely effects the individual functional performance with elderly population. ...

Radiological assessment of medial meniscuc tear of the knee
Within the knee, these structures provide strength to the joint enabling the knees to perform various functions like movement. Because of the functions performed by these structures, they remain highly prone to injuries among other problems (Jette & Jette, 1996). In layman’s terms, medical practitioners and patients commonly refer the meniscus tear of the knee as “torn cartilage”. Individuals participating in active sporting activities suffer most from meniscus tear resulting from traumatic forces encountered during these activities. These traumatic forces result from quick, twisting…

Acute Knee Sprain Assessment
The lateral and medial miniscal cartilage is cushioned between the boney surfaces of femoral condyles and tibial plateaus. The miniscal cartilage has tremendous tensile strength and during weight bearing it functions as a shock absorber. Anterior to the joint line is a large sesamoid bone which is known as patella. The lateral collateral ligaments and the medial collateral ligaments stabilize the knee and provide protection from knee dislocation during stress compression. The anterior movement of the tibia is limited by the anterior cruciate ligament. The Bursae of the knees are sac like…

The assessments that are done and the parental meetings between school administrations and the family are a central part of helping children gain a good and solid educational experience. The conclusion defines that without the implementation of IDEA many years ago there would still be many children missing out on the right to learn in a public environment. It also concludes that although there are still many issues that need to be worked out it is a positive influence in the educational system and does make a difference for many special needs children and the families.…

Assessment of Anterior Knee Pain due to Maltracking of Patella
Background Information: The angle of knee flexion is a very important parameter to be considered in the understanding of the pathophysiology of patellar maltracking. As the knee flexion proceeds, the quadriceps vector becomes more perpendicular, and the force on the patella gradually increases. This increasing force is transmitted by the quadriceps and is somewhat dissipated by the increased patellofemoral contact with increasing flexion. However, because the force increases more rapidly that the available surface area, with increasing flexion, the stress on the patella increases in a…

Microprocessor Prosthetic Knee Use for Transfemoral Amputees
The 19th century saw the use of more advanced lighter-weight prostheses made of wood. It has been found that amputations are largely due to trauma in developing countries while they are from vascular reasons in the developed countries.2 Vascular problems are usually associated with a lot of other illnesses which may limit a person's mobility and hence eliminate the urgent need for an advanced prosthesis. On the contrary, post-trauma amputees are usually younger with more active lifestyles and hence are candidates for advanced prosthetic placements so as to ensure uncompromised quality of life.…
