What is knee replacement?

If you find yourself facing difficulties in performing basic activities like walking or climbing stairs due to arthritis or knee injuries, along with experiencing pain even at rest, Knee Replacement surgery can provide a viable solution.

Knee replacement surgery, also known as Knee Arthroplasty or Knee Resurfacing, aims to replace the damaged portions of the knee joint, alleviating pain and discomfort.

This procedure involves creating an incision in the affected bone or cartilage and substituting it with an artificial joint (prosthesis)

What is the purpose of knee replacement surgery?

The purpose of knee replacement surgery is to alleviate pain and improve mobility in individuals with severe knee damage caused by arthritis, injuries, or other conditions.

By replacing the damaged joint surfaces with artificial components, the surgery aims to restore function, enhance quality of life, and enable the resumption of daily activities with reduced discomfort.

If your knee joint is severely affected by arthritis or injury, it may limit your physical activity, such as walking or climbing stairs. You may even experience pain at rest.

If medications, reduced physical activity, and the use of additional walking support no longer help, a total knee replacement may be considered. As a result of this operation, pain can go away, the deformity of the limb can be corrected, and normal physical activity can return.

One of the most significant achievements in orthopedics of the 20th century, total knee arthroplasty was first performed in 1968. Improvements in surgical materials and techniques since then have greatly increased the efficiency of this operation. In the US, approximately 300,000 of these surgeries are performed annually.

Knee Anatomy

The knee is a complex joint that connects the thigh bone (femur) to the shinbone (tibia). It is supported by ligaments, tendons, and muscles, allowing for stability and movement. The knee joint consists of the patella (kneecap), femur condyles, tibia plateau, and menisci, all working together to facilitate walking, running, and other activities.

What is the goal of knee replacement surgery?

The primary goal of knee replacement surgery is to relieve pain and improve the function and mobility of the knee joint. This surgical procedure is typically recommended for individuals with severe knee pain and limited mobility caused by conditions such as arthritis or joint damage. By replacing the damaged or diseased parts of the knee joint with artificial components, knee replacement surgery aims to reduce pain, restore range of motion, and allow individuals to engage in daily activities with greater ease and comfort.

Life after knee replacement surgery

Life after knee replacement surgery brings reduced pain and improved mobility, enabling individuals to regain an active and fulfilling lifestyle.

But, you must avoid certain movements and sports, including running and contact sports.

Even with normal use of the endoprosthesis, Its components, especially the polymer spacer, will wear out. If you experience increased stress on the joint or suffer from increased weight, the wear process can accelerate and cause instability of the prosthesis and renewed pain. With adequate use, a knee replacement can last for many years.

Is knee replacement surgery worth it?

The response would definitely be a resounding “Yes.” Similar to other surgical procedures, knee joint surgery presents certain possible complications, and naturally, numerous advantages.

but it is crucial to bear in mind that complications are seldom observed. Moreover, they can be averted by selecting a competent surgeon and taking into account pre- and post-operative precautions.

For most people, knee replacement provides pain relief, improved mobility and a better quality of life.

Who is a good candidate for Knee replacement surgery?

 Total knee arthroplasty can be classified into three primary categories:

 Osteoarthritis: This form of arthritis typically develops with age and commonly affects individuals aged 50 and above. It results in the degeneration of the knee joint’s cartilage, leading to pain and stiffness.

 Rheumatoid arthritis: This type of arthritis is an autoimmune disease that causes inflammation and damage to the joint’s cartilage, leading to chronic pain, swelling, and joint deformity.

 Post-traumatic arthritis: This condition occurs as a consequence of a severe knee injury or trauma, which can disrupt the normal functioning of the knee joint and result in long-term pain and limited mobility.


Iran takes pride in its orthopedic specialists, with over 100 surgeons having completed a rigorous four-year orthopedic residency program and pursued postgraduate courses in renowned medical universities. Many of these specialists have furthered their education in Europe and North America, specializing in various areas such as hand, spine, knee, and shoulder surgeries. With the substantial volume of orthopedic surgeries conducted annually, Iranian surgeons demonstrate the ability to compete with their counterparts in the best countries worldwide, delivering surgeries of unparalleled quality and efficacy.

Before Knee Replacement

Prior to the surgery, patients are advised to discontinue the use of specific medications such as Aspirin, non-steroidal anti-inflammatory drugs (NSAIDs), and herbal supplements. Smoking cessation is recommended several weeks before and after the surgery. Fasting from food and drink is typically required for approximately 6 hours before the procedure.

During Knee Replacement

you will be examined by an anesthesiologist. The most common types of anesthesia for total arthroplasty are endotracheal anesthesia (you will be asleep during the operation and the ventilator will breathe for you), spinal anesthesia or epidural anesthesia (which will allow you to breathe on your own, but your legs will not feel anything. Anesthesiologist will discuss with you the advantages and disadvantages of these methods and help you choose the most appropriate type of anesthesia.

The operation takes on average about two hours. The surgeon will remove the damaged cartilage and part of the bone and then install new metal and polymer articular surfaces in order to restore the axis of the limb and the function of the knee joint.

Many different types of prostheses are currently used in total knee arthroplasty. Almost all of them have three components:

  • the femoral component (made of highly polished, durable metal)
  • the tibial component (composed of a tough polymer, often placed on a metal platform)
  • patella (made of polymer).

After knee surgery:

After the operation, after full awakening, you will be transferred to your room.

You will be in the clinic for several days. After the operation, you will feel pain in the operated joint. You will receive pain medication to relieve pain.

Walking and light exercise for the operated joint is essential for recovery and should begin shortly after surgery.

To prevent lung complications, you must breathe deeper and cough more frequently.

The surgeon will take certain measures to prevent thrombosis and prevent swelling, such as elastic bandages, stockings, and the use of anticoagulants.

Foot and ankle exercises should also be done immediately after surgery and help increase blood flow to the extremities, reducing swelling and the risk of blood clots. Many patients begin knee exercises the day after surgery. Your physiotherapist will teach you specific exercises to strengthen your knee and restore the movement needed for walking and normal daily activities shortly after surgery.

Possible complications after surgery

The risk of complications after this operation is low.

  • Infection
  • Blood clots
  • Implant problems
  • Fracture
  • Nerve or blood vessel damage
  • Persistent pain or stiffness

Advantages of Knee Replacement Surgery:

  • Feeling relief from pain
  • Enhancement of mobility
  • Improvement of quality of life

Disadvantages of Knee Replacement Surgery:

  • Limited lifespan of prostheses may necessitate additional surgeries for younger patients.
  • Reduced range of motion compared to a natural knee joint.
  • Possibility of audible sounds or sensations within the replaced knee joint.


The success of the operation largely depends on how you follow the recommendations of the orthopedist at home during the first few weeks after the operation.

Careful attitude to the postoperative wound: Your wound will be stitched or stapled along the anterior surface of your knee joint, or it will be sutured with a subcutaneous suture. The braces or stitches will be removed approximately two weeks after surgery. The subcutaneous suture does not require removal.

It is necessary to be careful not to get water on the wound until it is completely sealed. You can put a bandage on the wound to prevent clothing or elastic stockings from irritating the wound.

Diet: A slight decrease in appetite is often present for several weeks after surgery. A balanced iron-rich diet is essential to assist in tissue healing and muscle strength restoration. Of course, you need to drink enough fluids.

Activity: Exercise is a crucial component of your home rehabilitation, especially during the first weeks after surgery. You should return to normal activities and daily life within 3 to 6 weeks after surgery. During this time, you will experience slight discomfort during active movements and at night.

Your activation program should include:

Gradually increasing duration of walking, first at home, and then on the street.

Practice essential movements such as sitting down, getting up from a chair, walking up stairs.

Return to the necessary household chores.

Special exercises a few minutes a day to develop movements in the knee joint.

Special exercises a few minutes a day to strengthen the knee joint.

It is possible to carry out physiotherapy activities at home.

Driving a car is possible when you develop movements in the operated joint in order to get into the car without difficulty and when the muscles can provide an adequate response when pressing the pedals. Most often this happens 4 to 6 weeks after surger

How is knee replacement performed in Iran?

Knee replacement surgeries in Iran are typically performed using general anesthesia, spinal anesthesia, or epidural anesthesia. During the procedure, the damaged bone ends of the knee joint are removed and replaced with custom-fit metal and plastic components, known as a prosthesis. The extent of knee damage determines whether a total or partial knee replacement is necessary, with total knee replacements being the most common.

Arthroplasty in Iran

After care knee replacement surgery 

The most common routes of infection after arthroplasty are through the introduction of bacteria into the bloodstream during dental procedures, urinary tract infections, and skin infections. These bacteria can infect the space around the prosthesis.

For up to two years after surgery, you may need to take prophylactic antibiotics before dental procedures, including cleaning of the enamel or other surgical procedures where bacteria can enter the bloodstream.

Be on the lookout for the following signs of an incipient infection:

  • Continued fever (temperature above 37°).
  • Fever or chills
  • Increasing redness, swelling, soreness in the area of the postoperative wound.
  • Discharge from the wound.
  • Increased pain during exertion and at rest.

Contact your doctor immediately if these symptoms occur!

  • Fall prevention.

A fall during the first weeks after surgery can damage the endoprosthesis and lead to the need for another operation. Be especially careful when walking up stairs. You should use a cane, crutches, walker, handrails, or other assistive devices until the joint is strong, mobile, or strong.

Your surgeon or physical therapist will advise you on the types of assistive devices you need after surgery and when it is safe for you to stop using those devices.

What is special about your new knee joint.

 The metal components of the joint can be detected by metal detectors at airports and other facilities. In such cases, inform the security staff that you had an operation with metal implantation. You can ask the surgeon for a certificate that you have implanted an endoprosthesis.

Be sure to do the following after surgery:

  • Take part in training programs to maintain the stability and mobility of the new joint
  • Follow special guidelines to prevent falls and damage. Patients who have suffered a fracture after total joint replacement may require new surgery.
  • Let your dentist know that you have had a total arthroplasty. Antibiotics are required before dental procedures for up to two years after surgery, possibly more, depending on the course of the postoperative period. Recommendations for the use of antibiotics for the surgeon and dentist are available on the AAOS and ADA websites.
  • Periodically see the surgeon for examination and x-ray control, even if you do not experience any problems with the joint.
