 KNEE REPLACEMENT SURGERY: WHAT IS IT? KNEE REPLACEMENT: WHAT IS IT?

Total knee replacement arthroplasty, sometimes referred to as knee replacement surgery in Noida and Delhi, is a surgical technique in which doctors use artificial implants or materials to replace the worn-out surfaces of the bones that make up the knee joint.
In a total knee replacement, only the damaged area of the bone is cut out, and prosthetic pieces or implants are put to cap the ends of the bones instead of actually removing and replacing the bone that makes up the joint. The phrase "knee resurfacing procedure" is preferable. Patients with osteoarthritis have this surgery to relieve joint discomfort and impairment.

Another form of knee replacement surgery is partial knee replacement. Partial knee replacement surgery is performed rigidly in a partially damaged knee. It is less invasive yet is as good as total knee replacement surgery. Here the knee is opened up and a prosthesis (prosthesis) is placed over the damaged area. Partial knee replacement surgery is preferred in younger patients.

 

WHO CAN HAVE KNEE PAIN?

 

Generally, knee pain can occur at any stage in women, men, children, and old people. This disease is a little more troublesome in old age. The joints formed between the legs are called knees. The work of the knees is done in many types of work, from getting up and walking to walking. When there is a pain in these joints, then the daily routine of the person changes. There are many reasons behind this pain, which can last for a short time and have the potential to trouble you for life. due to the increasing workload day by day, going to the office in the morning and then sitting at your desk and having breakfast, tea, and lunch, all this is also considered a big reason for knee pain. Keeping the feet in the same position for a long time has a very bad effect on the knees.

Frequently asked questions about Knee Replacement?

 

In arthritis that causes pain and disability, total knee replacement is the most common reason for surgery. In addition, total knee replacement surgery may be required in the following cases:

 

  • Osteoarthritis (a condition causing painful inflammation in the joints)
  • Other conditions, such as rheumatoid arthritis
  • The knee injury that leads to arthritis
  • Fracture, Ligament tear, Cartilage tear resulting in severe damage to the knee
  • Severe and chronic knee pain
  • Swelling in the knees that cannot be reduced with medicine
  • Joint stiffness
  • Low-speed limit
  • Limp
  • Joint deformity

  • Before knee replacement surgery, Dr Vaibhav Jain may do some tests to diagnose problems with your joints.

     

    • Physical examination – The patient is examined in a lying position. The doctor then looks for signs of joint inflammation, joint deformity, and muscle damage. The doctor then feels the joint to check for warmth, swelling, fluid, and tenderness of the joint. In addition, doctors check the range of motion of the joint by rotating the knee back and forth to check for any stiffness of the joint.
    • Blood tests – Special blood tests may be done to check the level of inflammation or the presence of antibodies. For example, the presence of rheumatoid factor (RF) in the blood may indicate the presence of autoimmune disease, particularly rheumatoid arthritis. Common blood tests like CBC, blood glucose, kidney function test, and liver function test are done beforehand.
    • Joint aspiration – In this procedure, a small sample of fluid is collected from the knee joint using a needle and sent for further examination. This is done in selected patients only when needed.
    • Imaging tests – The most commonly used imaging tests are X-rays as they help to see structural changes, signs of joint wear, loss of cartilage or tissue tearing, swelling, amount of fluid present, etc. Sometimes an MRI or CT scan is planned to obtain further information.

     

    4. HOW IS KNEE REPLACEMENT DONE?

    Knee replacement surgery is performed under spinal or general anaesthesia.

     

    • During knee replacement surgery, a cut is made on the skin at the front of the knee to access the kneecap (patella). The patella is then rotated outwards to get a better view of the area that needs repair.
    • The femur, the lower end of the thigh bone, is then measured and brought back to the front. The damaged portion of bone and cartilage is cut from the lower end of the femur using special instruments and then fitted to the metal femoral component of the prosthetic knee.
    • After, the tibia (shin bone) is regenerated by removing the damaged bone and cartilage from the upper end of the tibia and then reshaped to fit the plastic or metal tibial component.
    • The patella is re-adjusted. The damaged part of the patella is repositioned and fitted with a patellar button, or the patella is reshaped. The surgeon adds a plastic spacer between the femoral and tibial components to avoid friction between the prostheses.
    • The prosthesis is usually attached to the bone by surgical cement and is known as a cemented prosthesis.
    • The function of the replacement is checked by bending the knee and the incision is closed with sutures or surgical staples.
    • Knee replacement surgery in the right way can provide your knee with function for about 10 to 15 years.
  • Joint tenderness
