Essay On Knee Joint

The knee joint is one of the strongest and most important joints in the human body. It allows the lower leg to move relative to the thigh while supporting the body’s weight (Taylor, n.d.) as knee joint is one of the major weights bearing joint in the body. Knee joint plays an important role in our daily lives such as walking, running, sitting and standing. It allows physiological movement such as flexion and extension. The knee joint is also known as tibiofemoral joint. It is a synovial hinge joint formed between three bones which are the femur, tibia and patella (Taylor, n.d.). There are two rounded, convex processes which are known as condyles on the distal end of the femur. The distal end of the femur meets two rounded, concave condyles at the proximal end of the tibia (Tyalor, n.d.). A thick, triangular bone which is known as patella lies anterior surface between the femur and tibia.

In each knee joint, there is two pieces of C-shaped cartilage which lies between the surfaces of the femur and tibia. The lateral side of the meniscus is known ad lateral meniscus while the medial side is known as medial meniscus. The major role of the menisci is to absorb the impact load between the femur and tibia and also to provide some degree of stabilization to

In same studies it showed that among the subjects between 25 and 74 years of age, the prevalence of knee symptoms such as pain, swelling and morning stiffness increased with age and knee pain was slightly higher among women compared to men (Hannan et al, 2000). Knee pain is very likely a health problem with tremendous health care costs, despite the lack of direct cost estimates. In 1996–1997, more than 6 million Americans sought medical care for knee problems (Peat et al
