Knee Replacement

What is Knee Replacement?

Knee replacement, also known as knee arthroplasty, is a surgical procedure that replaces a damaged or worn knee joint with an artificial joint (prosthesis). This orthopedic surgery is typically performed to relieve pain and restore function in severely damaged knee joints, most commonly due to osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis. The procedure can be either total knee replacement (replacing the entire joint surface) or partial knee replacement (replacing only the damaged portion), depending on the extent of joint damage.

Procedure Details

During knee replacement surgery, the surgeon removes damaged cartilage and bone from the femur (thigh bone), tibia (shin bone), and patella (kneecap), and replaces them with metal and plastic components. The procedure begins with an incision over the front of the knee, followed by careful removal of damaged surfaces. The ends of the bones are precisely shaped to fit the prosthetic components, which are then secured using bone cement or press-fit techniques for biological fixation. The artificial components recreate the surface of the joint, with a high-density plastic spacer inserted between the metal components to create a smooth gliding surface. Modern techniques include minimally invasive approaches, computer-assisted navigation, patient-specific instrumentation, and robotic-assisted surgery for enhanced precision and potentially faster recovery.

Recovery Information

Benefits

• Significant pain relief from arthritic symptoms
• Improved mobility and joint function
• Correction of deformity (bow-legged or knock-kneed alignment)
• Enhanced quality of life and independence
• Ability to resume moderate activities like walking, swimming, and cycling
• Durable results lasting 15-20 years or longer
• High patient satisfaction rates (over 90%)
• Reduced dependence on pain medications

Why Choose Iran for Knee Replacement

Iran offers numerous significant advantages for international patients seeking knee replacement surgery:

• Renowned Orthopedic Surgeons: Iranian orthopedic specialists are internationally recognized for their expertise in joint replacement, with many having trained at prestigious global institutions
• Exceptional Cost Savings: Knee replacement in Iran costs 75-85% less than in Western countries, with comprehensive packages starting from $3,500-$6,000 (compared to $30,000-$50,000 in the US or Europe)
• Advanced Surgical Techniques: Iranian orthopedic centers offer the latest approaches including minimally invasive surgery, computer navigation, and robotic-assisted procedures
• Premium Implant Options: Access to high-quality prosthetic joints from leading global manufacturers at a fraction of Western prices
• Comprehensive Pre-operative Assessment: Thorough evaluation ensuring optimal surgical planning and outcomes
• High Success Rates: Iranian orthopedic centers report outcomes comparable to leading global institutions
• Minimal Wait Times: Quick scheduling with virtually no waiting lists, unlike many countries where joint replacement may have months-long waiting periods
• All-Inclusive Packages: Comprehensive care covering pre-operative assessment, surgery, post-operative care, rehabilitation, accommodation, transportation, and interpreter services
• Integrated Rehabilitation Programs: Structured physical therapy to optimize recovery and long-term outcomes

Risks and Considerations

• Infection at the surgical site or around the prosthesis
• Blood clots in the leg veins or lungs
• Implant loosening or wear over time
• Nerve or blood vessel damage
• Persistent pain or stiffness in some cases
• Potential for implant failure requiring revision surgery
• Limited range of motion compared to a natural knee
• Need for activity modifications to protect the implant

Ideal Candidates

Ideal candidates for knee replacement include individuals who:- Experience severe knee pain that limits daily activities- Have moderate to severe knee pain while resting- Have chronic knee inflammation and swelling unresponsive to medications- Show knee deformity (bow-legged or knock-kneed)- Have failed conservative treatments like medications, injections, and physical therapy- Are typically over 50 years old (though younger patients may qualify in certain cases)- Have realistic expectations about post-surgical activities- Are in generally good health for surgery

Preparation for Travel to Iran

Before traveling to Iran for knee replacement, patients should:- Consult with their chosen Iranian orthopedic center remotely- Complete comprehensive orthopedic evaluation in their home country and share results- Obtain necessary medical visa (facilitated by most medical tourism providers)- Optimize management of existing conditions like diabetes or hypertension- Strengthen muscles around the knee through prescribed exercises- Stop smoking and maintain healthy weight if possible- Arrange for appropriate mobility aids for the recovery period- Pack comfortable, loose clothing and supportive shoes- Prepare for a 10-14 day stay in Iran for the procedure and initial rehabilitation

Post-Operative Care in Iran

After knee replacement in Iran, patients benefit from:- Immediate post-surgical care in specialized orthopedic units- Pain management with appropriate medications and techniques- Early mobilization with physical therapist guidance- Daily rehabilitation sessions to improve strength and range of motion- Regular check-ups with your surgeon during your stay- Dedicated medical tourism coordinators to assist with any needs- Comfortable recovery accommodations- Translation services for all medical communications- Detailed instructions for continued rehabilitation upon returning home- Remote follow-up consultations as needed

Long-Term Results

Modern knee replacements have excellent longevity, with studies showing 90-95% of implants still functioning well after 15 years. Patients who undergo knee replacement in Iran report outcomes comparable to those achieved at leading global centers but at a fraction of the cost. Most patients experience significant pain relief and functional improvement within 3-6 months after surgery. While high-impact activities like running and jumping are generally discouraged to protect the implant, patients can typically enjoy walking, swimming, cycling, and golf with their new knee. Long-term success depends on maintaining a healthy weight, following activity guidelines, and attending regular follow-up appointments.
