Knee replacement or knee arthroplasty is an orthopedic surgical treatment for those suffering from arthritis, leg deformity, and knee inability to work well. In the recent decade, the demand for the surgery has been on the rise in Iran. More than 10,000 knee arthroplasties are performed annually in the country. In light of this, and with the introduction of medical tourism, more patients travel to Iran to get their knee reconstruction surgery done here. In this article, we present an overview of this surgery in Iran, including procedure, reasons, benefits, costs, outcomes, and everything.
Is Iran a good option for knee replacement surgery?
Knee surgeries are among the most popular and in demand orthopedic procedures performed in Iran. There are three main reasons that make Iran a perfect destination to choose for the replacement of a knee joint. They include professional surgeons, state-of-the-art orthopedic facilities, and attractive prices. Member of the Iranian Society of Knee Surgery, Arthroscopy and Sports Traumatology, Dr. Yazdi, explains the development of orthopedic surgeries in Iran, in an interview with Iran Daily. “We have made good progress in orthopedic treatments and knee surgery, and currently, we can conduct the most complicated knee surgeries,” he said. Therefore, Iran has a lot to offer to both national and international patients to have the most cost-effective and safe arthroplasty in the country.
Best orthopedic surgeons in Iran
Having a successful surgery relies on the knowledge and proficiency of the surgeon. With many years of training and performing hundreds of surgeries, Iranian orthopedic surgeons are qualified for performing knee replacement surgeries. Iranian surgeons have passed orthopedic residency (a four-year program) and then attended postgraduate courses in top medical universities. Many orthopedic specialists in Iran have also furthered their education in Europe and North America for subspecialization in the hand, spine, knee, and shoulder surgeries. Furthermore, with the great number of orthopedic surgeries they carry out annually, Iranian surgeons can compete with those in the best countries in terms of quality and efficacy of surgeries.
Total knee replacement in Iran?
Total knee replacement surgery involves removing the knee joint and replacing it with a man-made joint. Depending on the patient’s age and condition, general anesthesia, regional nerve block anesthesia, epidural, or spinal are used for the safe operation. Depending on the method, either an incision between 6-10 inches or a big cut is made. Then, the surgeon moves aside the kneecap, cuts away damaged cartilage and bone end, and replaces new metal and plastic implant. The surgeon either retains, sacrifices, or substitutes the ligament and restores the alignment of your knees. After checking your knees by rotating them, the surgeon closes the incision. The procedure usually lasts between 2 and 4 hours. It takes place in a private hospital or specialized orthopedic center. You will need to stay 1-4 days in the hospital after the surgery.

Total knee replacement cost in Iran
While having a knee surgery would cost a fortune in many countries, Iran stands out in the front line of orthopedic destinations with the most affordable prices. A total knee replacement in Iran costs from $2,800 to $3,800. However, the same procedure would cost around $50,000 in the US and $11,000 in the UK. This price is going through the roof in other Asian countries compared to Iran. For example, the average price of this surgery is $12,000 and $7,000 in Thailand and India, respectively.
Why is a total knee arthroplasty needed?
There are three main categories of arthritis posing the necessity of total knee arthroplasty. They are:
- Osteoarthritis: This arthritis occurs as a result of aging, usually among people aged 50 or more. In this type of arthritis, the cartilage starts to soften and the ends of the bones hit each other, causing the knee pain.
- Rheumatoid arthritis: This arthritis, which falls into the category of inflammatory arthritis, occurs when the synovial membrane is thickened, damaging the cartilage and causing severe pain.
- Post-traumatic arthritis: Serious knee damage leads to post-traumatic arthritis which ills the functionality of the knee.
If you are suffering from a type of arthritis described above, you definitely need a total knee replacement surgery. Knee stiffness and pain are the main reasons for this particular knee treatment. If you observe swelling and inflammation, which is not treated by anti-inflammatory medications and rest, you need to go for a joint replacement.
Am I a good candidate for total knee replacement?
You are a good candidate for this surgery if you:
- Are suffering from one of the mentioned arthritis, such as osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis;
- Have increasing knee pain;
- Feel stiffness in your knee;
- Are suffering from low functionality of your knees;
- Have knee pain while resting; and, of course,
- Have realistic expectations of the surgery.
Partial knee replacement
When you start to experience knee pain, total knee replacement is not the only option for you. When only one part of your knee is damaged, a partial knee replacement might suffice for you. Your knee consists of three compartments (medial, lateral, and patellofemoral). In partial knee replacement, otherwise known as unicompartmental knee replacement, only one area of your knee (the damaged compartment) will be replaced and resurfaced. The cartilage, bone, and ligaments will remain intact. The procedure is less invasive but takes more precision. The recovery is quicker with less pain. To realize whether you’re the right candidate for partial knee surgery, specific tests should be done before the operation.
What are some knee replacement outcomes?
Like other surgeries, total knee replacement has some potential risks, complications, and, of course, benefits. Blood clots, dislocation, infection, fracture, implant problems, neurovascular injury, component misalignment, swelling, nerve injury, and stroke are all the complications you may experience after surgery. However, it is important to keep in mind that these complications are rarely observed. Plus, they can be prevented if you choose the right surgeon and consider post- and pre-operative cares.
Generally, the knee surgery aims at eliminating your knee pain, and studies show that above 90% of patients who undergo this surgery experience a dramatic reduction of knee pain. According to a report, several studies confirm that knee surgery improves knee function as well as the quality of life in patients with osteoarthritis. Therefore, the surgery would guarantee the patients’ health and well-being rather than threatening their life.
What to do before a total knee arthroplasty?
Before the surgery, make sure your surgeon teaches you post-operative exercises. Pre-operative physiotherapy also has a significant effect on the result of the procedure after it is done. Walker or crutches need to be prepared before the surgery, as you will need to use them during the recovery period. Having a caretaker, or one of the house members to do the house chores is also required as you may be unable to cook, bathe, and do the laundry. It is necessary to ensure safe transportation after the surgery. As climbing stairs are forbidden during recovery, it is better to have a living place on one floor. You definitely need a comfortable chair or bench with a footstool to elevate your legs. You may even use it while taking a shower. Some pre-operative tests are also needed, such as:
- A physical examination
- Blood tests
- Urinary evaluations
- A medical history
- Active and passive ROM
- Dental evaluation
- Examination of muscle power
- Examination of functional tasks
What are knee replacement recovery and post-operative cares?
In order to get the most out of your surgery, you need to follow some post-operative instructions. These include:
- Use knee support to move your leg during the recovery period;
- Have regular physiotherapy after the surgery;
- Take non-steroidal anti-inflammatory drugs (NSAIDs);
- Take frequent deep breaths;
- Several weeks after the surgery, remove your sutures or staples;
- Take an iron supplement;
- Have a nutrient and balanced diet;
- Take antibiotics and blood thinners;
- Do the exercises suggested at least twice a day;
- Try to return to your normal routines as instructed by your physician;
- Have x-ray check-up for your leg every year.
