Knee Replacement
The knee arthritis treatment in Delhi is composed of three separate bones. They are the lower end of the thigh bone (the femur), the upper end of the shin bone (the tibia) and the knee cap (the patella). These three bones are joined together in a loose arrangement by a surrounding capsule. In addition, there are special ligaments which blend with the capsule outside the knee and provide additional reinforcement. In particular, there are medial and lateral ligaments which help stop the thigh bone and the shin bone from moving sideways upon each other. There are also ligaments inside the knee joint. In particular, there are the anterior cruciate and the posterior cruciate ligaments. These ligaments provide stability in a frontwards to backwards direction, and also provide rotary stability. There are two cartilages or menisci within the knee. These serve to increase the surface area for load distribution, act as cushions or shock absorbers between the femur and the tibia. A normal joint contains between 0.5ml and 2ml of fluid. The knee joint is special in that the bones can hinge, glide and rotate. The joint surfaces are covered with hyaline cartilage.
