Arthroplasty means repairing a joint through surgery using artificial components.When a particular cartilage in the body is damaged or destroyed, it becomes painful and cannot be shaken, and as a result, the bones may clump together and break each other, in this case the patient may have severe pain.

In this process, the damaged parts of the cartilage are removed from the thigh and it is replaced with an artificial joint made of high quality metal, plastic and polymer. To find out if this knee replacement surgery is right for you, you should see an orthopedic surgeon to check your age, weight, activity level, knee size and shape and your overall health.

What is the procedure of total knee arthroplasty?

At the beginning of the surgery, an incision about 15 to 25 centimeters long will be made on the joint position of the knee, providing enough space for the surgeon to reach kneecaps and cutaway surfaces of damaged joints. During the total knee arthroplasty, damaged bones of knee joints are cut away and cartilage from thighbones, knee cap, and shinbone. The second step during this surgery is to replace the damaged parts with a prosthesis, which is an artificial joint made of polymers, metal alloys, or plastic. Type of prosthesis and surgical techniques are chosen by surgeons based on different factors, such as weight, knee size, and shape, overall health condition of the patient, his or her age, and activity level. A typical total knee arthroplasty will take about two hours. This time can be prolonged in the case of unpredicted complications during the surgery.

Knee replacement surgery step by step:

  • The surgeon starts the operation by a small cut in front of your knee to get access the patella bone.
  • The patella bone will be removed from the knee joint.
  • When your knee joint expose directly, the bones diameter and length will be measured by your surgeon and a proper and exact cut will be made in the bones.
  • The metal part of implant attach to the distal part of femoral bone. The attachment graft by bone powder.
  • The lower part of the implant attaches to tibia bone of the leg and fixed by bone powder.
  • Before putting the patella bone on the knee joint, the surgeon may sleek the patella bone and repair the joint by a plastic material to fix and coordinate the total knee joint.
  • Finally, the surgeon will flex and extend your knee joint to check accurate function of the knee.

When knee replacement surgery is done over knee joint?

When the knee joint is damaged due to injuries, it can cause severe pain that can keep a person away from even simple activities such as climbing stairs or walking. Pain may even be present while sitting and sleeping. If the use of medication, changing the level of daily activities, and the use of cane does not alleviate the patient’s problems, knee replacement surgery is usually the last option. The knee joint is one of the most complex joints in the body. This joint may be damaged due to bone arthritis, osteoarthritis, rheumatoid arthritis, and arthritis caused by a lesion and may require a knee replacement surgery by a specialist. Surgeon can generally replace a knee joint with an artificial joint.

Anatomy or knee joint structure

The knee joints are one of the largest joints in the body. This joint is made up of three bones. Lower thigh, upper leg, and patella. The surface of the areas where these three bones are in contact is covered by cartilage, and the ease of movement of these three bones is due to the slippage of this surface. Inside the knee joint is a fluid that lubricates the cartilage and makes the joint easier to move. This fluid is known as articular fluid or synovial fluid. The knee miniscule is located between the leg bone and the femur. This C-shaped bone is like a cushion in the knee joint.

Causes and reasons of knee replacement surgery

The main reason for knee replacement surgery is arthritis. Although arthritis has many different types, the most common type of arthritis is of the following three types: Osteoarthritis – Rheumatism – Arthritis

  • Bone Arthritis

This type of osteoarthritis can occur as people age 50 or older, and can occur at a young age, as a result of overwork. bones wear out and cause pain. If the knee joint is damaged by arthritis or by trauma, very simple activities such as walking and climbing stairs will be difficult for you. It may even be painful to sit or lie down.

  • Osteoarthritis

Knee arthritis is the most important cause of knee joint in people over 40 years of age. Knee arthritis is the most common destructive disease in the joints of the body. In arthritis, the joints become dry and painful. Also, the patient may not use the joint because of the severe pain, so the muscles around the joint weaken and even – the joint movement becomes very difficult. In such a case the knee replacement surgery is necessary.

  • Rheumatoid Arthritis

In rheumatoid arthritis the synovial membrane grows and becomes inflamed and releases a large amount of fluid. Inflammation of the synovial membrane gradually destroys and damages the knee articular cartilage, thereby causing pain and movement limitation of the knee joint.

  • Rheumatism

In this type of nosocomial disease, the joints around knee become thick and swollen. This swelling causes damage to the cartilage and eventually their loss, pain and tightening. Rheumatism is one of the most common types of inflammatory arthritis which in severe cases require knee replacement surgery.


Knee replacement surgery is suitable for people with the following conditions:

  • People who feel pain or severe stiffness in the knee that they suffer from daily activities such as walking, climbing stairs, getting on and off the car, climbing a chair and etc. will need knee replacement
  • Persistent knee pain which is felt while sleeping and resting is another symptom. Chronic inflammation of the knee and swelling in these cases will not resolve after taking medication and rest.
  • Deformity of the knee, which is quite obvious, sometimes leading to bracing or cracking of the legs.
  • Ineffective treatment options other than surgery in patients with knee pain.

Types of knee arthroplasty 

Total knee articulation surgery or TKR:

  • In total knee arthroplasty  surgery, both sides of the knee joint cartilages are removed. This process is quite common. The surgery takes about 1 to 3 hours and then the pain is lessened, but the scar tissue around the surgical site may prevent the patient from bending or moving easily.

Partial replacement of knee joint or PKR :

This type of replacement occurs only on one side of the knee joint. Fewer bones and cartilages are removed and therefore less surgical incision and shorter duration than total dislocation surgery.

Partial knee replacement surgery is appropriate for those with only one part of their knee injured. Physical activities and exercises begin immediately after surgery, and blood loss is less, thereby reducing the risk of infection and blood clots.

Benefits of total knee replacement surgery

The most important benefit of knee replacement surgery is that the patient’s pain disappears and the brackets and crosshairs of the legs are removed. Most patients who suffer from knee pain do not have the ability to sit and walk properly and can perform their activities well after knee arthroplasty surgery. The sounds produced by the knee are eliminated when walking on the knees.

For many people, knee surgery removes pain, improves movement and a better quality of life, and most of these joints last up to 15 years.

Driving is also recommended after three weeks if you are fully capable of bending your knee. Of course, if you have enough control over the muscles.

What are the post-operation instructions for total knee arthroplasty?

After the surgery, patients will be held in the hospital for a few days. During this post-operation observation, patients will be encouraged to move their foot to increase the blood flow to their leg muscles. This increase in blood flow helps them to prevent blood clots and swelling in the knee parts. The patient will be further protected from swelling and clotting by receiving blood thinners, compression boots, and wearing support hoses. Patients need to follow a special diet before and after knee replacement surgery or knee arthroplasty. Physical therapy sessions are recommended after the surgery, during which patients will receive exercises on their knee. After discharging from hospital patients are encouraged to follow instructions below at home:

  • Using secure stairway handrails
  • Avoiding climbing stairs as far as you can
  • Install handrails and safety bars for shower and baths.

After discharge from the hospital, your joint flexion and extension ranges between 10 to 80 degrees. In next 6-12 weeks, knee movement ranges between 0 to 110 degrees. In next 6 to 12 months after knee replacement surgery, knee pain relief to a great extent. Your surgeon will explain all needed physical activities and prescribe pain medicine and advice to lie down and raise your operated leg and put ice packs near your surgical knee for several days after your surgery.

Knee replacement surgery

Knee arthroplasty surgery is a medical procedure during which severely damaged knee joints get replaced. This procedure relieves pain and restores the functionality of the patient’s knee. The orthopedic surgeon usually examines the range of motion, strength, and stability of knee joints along with X-rays to understand the extent of damage to knee joints. If the patient meets the criteria, then the total knee arthroplasty will be recommended.

What is the success rate of total knee arthroplasty?

The success rate of total knee arthroplasty is somewhat high. About 97 percent of surgeries of this kind are usually successful.

What are the risks and side effects of total knee arthroplasty?

Similar to other medical procedures, the total knee arthroplasty has its risks and side-effects. These risks include:

  • Blood clots in the lungs or the leg vein which is named DVT or pulmonary embolism (PE).
  • Heart attack or MI
  • Stroke or CVA
  • Nerve damage
  • Infection in surgical site

Infection is one of the most dangerous and frequent risks of total knee arthroplasty. If it happens, the infected parts should be removed during another surgery, and antibiotics are prescribed as follow up treatment. After the elimination of infection, another surgery is needed to install a new knee joint.
