Knee Replacement Surgery in Lucknow

In principle, Total Knee Replacement or TKR is the replacement of the diseased knee joint by an artificial implant. Many decades ago, the relatively simple structure of the knee joint – the condyle of femur and distal tibia – had inspired surgeons and medical technicians to create an artificial copy, and in the course of time, follow – up examinations and improvements in operative methods and materials have led to great progress, and the optimization of total knee prosthesis.

The knee prosthesis is designed to simulate the human anatomy to knee joint and is comprised of a femoral component, tibial base plate, polyethylene insert and patellar components.

The femoral component will fit in the condyle portion of femur bone; the tibial base plate will fit on the distal tibia, polyethylene insert will act like the cartilages, the patella component will resemble the original patella. The femoral component will glide smoothly over the polyethylene insert, thus allowing you to walk, squat and turn without pain.

These components are made up, of metal, ceramic or polyethylene. All these materials have been specially developed for medical purpose with good tissue tolerance and allow the function to be as painless and lasting as possible.

Over the years your knee joint takes many stresses and strains during daily activities. When a disease process or injury to your knee occurs, the cartilage surface of the knee joint degenerate or wear out.

During total knee replacement surgery, the diseased and / or arthritic ends of the bones are removed. A metal component is secured to the femur and plastic components are attached to the tibia and patella. In this way, the smooth surfaces of the knee joint are restored, pain-free motion is again possible and it works as a normal knee joint.

For each implant type, there is a wide range of models manufactured in different sizes as the anatomy of the knee varies from one individual to another. The surgeon will prepare for the operation on your knee joint with a graphic plan compiled on the basis of X-rays and will thus determine the model, size and position of the implant parts.

Material used for artificial joints are highly developed. They provide maximum tolerance and long-term acceptance by the human body, which is called bio-compatibility. Material development and fundamental know-how in metallurgy, material, research and testing. In general, there are two different types of material employed for orthopedic purposes Metals & Polymers (ultra high molecular weight polyelrylene).

• Persistent pain in the joint recurring regular pain killers, affecting activities of daily living & compromising your quality of life.
• When other treatments like medicines, plysiotherapyetc have failed and no other alternative treatment is likely to.
• X-ray confirming advanced arthritic changes in the joint.
