Knee Replacement Surgery Procedure

Knee Replacement Surgery Procedure

Knee replacement surgery, also called knee arthroplasty, can help in pain relief and restore function to seriously diseased knee joints. In this procedure, damaged bone and cartilage of the femur, tibia, and kneecap are cut and replaced with an artificial joint (prosthesis) made of high-quality metal alloys, plastics, and polymers. If you are looking for the best knee replacement hospital in Gurgaon, then you must visit the CK Birla Hospital in Gurgaon. The hospital’ Orthopaedics expert offers the best diagnosis and comprehensive treatment for both women and men with musculoskeletal, bone, and joint disorders.

When to opt for Knee Replacement Surgery

Knee replacement surgery is for disability and pain in the knee. Osteoarthritis is the most common condition that results in the need for knee replacement surgery.

Osteoarthritis is distinguished by the breakdown of joint cartilage. Damage to cartilage and bones restricts movement and can cause pain. People with severe degenerative joint disease may not be able to perform normal activities that involve bending the knee, such as walking or climbing stairs because it hurts. The knee may swell because the joint is not stable.

Other forms of arthritis, such as rheumatoid arthritis and arthritis resulting from a knee injury, can also lead to degeneration of the knee joint. In addition, fractures, torn cartilage and/or torn ligaments can lead to irreversible damage to the knee joint.

When medical treatments fail, knee replacement surgery can be an effective treatment. Some medical treatments for degenerative joint diseases may include, but are not limited to:

  • Glucosamine and chondroitin sulfate
  • Pain medications
  • Anti-inflammatory medications
  • Limiting painful activities
  • Weight loss (for obese persons)
  • Physical therapy
  • Cortisone injections into the knee joint
  • Viscosupplementation injections

So many other reasons are also responsible for your doctor to recommend a knee replacement surgery.

Knee Replacement Surgery Procedure

To determine if a knee replacement is right for you, an orthopaedic surgeon will assess the range of motion, stability, and strength of your knee. X-rays help determine the extent of the damage.

Your doctor can choose from a variety of knee replacement prostheses and surgical techniques, taking into account your age, weight, activity level, knee size and shape, and general health.

a) Making the knee incision

In the very first step, the surgeon makes an incision in the front of the knee to access the kneecap (patella). For minimally invasive knee surgery, the incision is typically 4 to 6 inches long.

b) Rotating kneecap (patella)

Once the knee is open, the surgeon rotates the kneecap outside of the knee area. This allows the surgeon to see the area needed to perform the surgical procedure.

c) Preparing the thigh bone (femur)

The first bone the surgeon reappears on is the femur is also known as the thigh bone. Once the surgeon has opened and exposed the knee joint, he will carefully measure your bones and make precise cuts with special instruments. The damaged bone and cartilage are cut at the end of the femur. The end of your femur will be cut and re-emerged to match the first part of the artificial knee, the femoral component.

d) Implanting the femoral component

The surgeon places the metallic femoral component at the end of the femur and seals it with bone cement.

e) Preparing the tibia (shinbone)

The next bone that your surgeon will reappear is the tibia or shinbone. The surgeon removes damaged bone and cartilage from the top of the tibia, then shapes the bone to match the tibial metal and plastic components.

f) Implanting the tibial component

The lower part of the implant is the tibial tray, which is attached to the tibia and secured with bone cement. Once the shell is in place, the surgeon inserts a polyethene (medical-grade plastic) that fits between the tibial tray and the femoral component and acts as a lubrication substance. This will support your body as you bend and bend your knee.

g) Re-adjusting the patella

Before returning the patella to its normal position, the surgeon may need to flatten the patella and position it with an additional plastic component to ensure a good fit with the rest of your implant. The plastic part is glued to the underlying bone if necessary.

h) Completing the procedure

Your surgeon will flex and bend your knee to make sure the implant is working properly and that the orientation, size, and position are correct. To complete the procedure, the surgeon closes the incision with stitches or staples, then bandages and prepares you for recovery.

Risk Associated with the Procedure

Knee replacement surgery, like any surgery, carries risks. They include:

  • Infection
  • Heart attack
  • Stroke
  • Blood clots in the vein or lungs
  • Nerve damage
