FAQ

What is Total Knee Replacement?

TKR is the replacement of the diseased knee joint by an artificial implant. Over the years, your knee joint takes many stresses and strains and strains during daily activities. When a disease process or injury to your knee occurs, the cartilage surfaces 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.

What are artificial knee joints made up of?

Materials used for artificial joints are highly developed. They provide maximum tolerance and long-term acceptance by the human body, which is called biocompatibility. In general, there are two different types of material employed for orthopedic purposes Metals & polymers (ultra high molecular weight polyethylene).

When is Total Knee Replacement required?

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

What is Total Hip Replacement?

THR is the replacement of the diseased joint by an artificial implant. The hip is a simple ball-and-socket joint where the thighbone joins with the pelvis. When these joint surfaces become roughened, causing severe pain and stiffness, the ball-and-socket has to be replaced.

Total hip replacement is when a cup is inserted into the pelvis and fixed into place and a stem with a head attached is inserted into the shaft of the femur. The artificial ball-and-socket is then fitted together to function as a normal hip joint. For each prosthesis type, there is wide range of models, manufactured in different sizes. Selection of the prosthesis is dictated by the bone condition and the weight and physical activities of the patient. The surgeon will prepare for the operation on your hip with a graphic plan compiled on the basis of X-rays and will thus determine the model, size and position if the prosthesis parts.

What are artificial hip joints made up of?

Materials used for artificial joints are highly developed. They provide maximum tolerance and long-term acceptance by the human body, which is called biocompatibility. In general, there are three different types of material employed for orthopedic purposes: Metals, Polymers, and Ceramics.

  • When other treatments like medicines, physiotherapy, etc. have failed and no other alternative treatment is likely to help.
  • X-ray confirming advanced arthritic changes in the joint.
