Knee replacement surgery removes damaged cartilage and bone surfaces from the knee joint and replaces them with metal components and high-grade medical plastic (polyethylene) implants designed to restore smooth movement and relieve pain.
The procedure addresses osteoarthritis, rheumatoid arthritis, and post-traumatic joint damage that has not responded to conservative treatment.
Total knee replacement reshapes all three compartments — the medial, lateral, and patellofemoral — and replaces each surface. Partial (unicompartmental) knee replacement targets only the worn compartment, preserving healthy bone and tissue elsewhere.
Korean hospitals participating in KOIHA accreditation and KHIDI (Korea Health Industry Development Institute) programmes use robotic-assisted and computer-navigated alignment systems to plan and guide bone preparation with sub-millimetre accuracy.
Rehabilitation begins within the first day of surgery. Ask the hospital whether its surgical team can review your X-rays and MRI scans before you book flights.
Send your imaging before you fly
Ask the hospital whether its surgical team can review your X-rays and MRI scans before you book flights. This confirms candidacy and allows the team to pre-select implant sizing, reducing delays after arrival.
Flying after major joint surgery
Long-haul flights carry an elevated deep vein thrombosis risk in the weeks after knee replacement. Flying clearance is given by your surgeon at the end of the recommended 14-day stay — not on a fixed-date basis. Travel with prescribed blood-thinning medication, compression stockings, and written instructions for in-flight movement.
Bring your implant record home
Before discharge, ask the hospital for a full implant record including make, model, and lot number. Your home physiotherapist and family doctor need this for safe ongoing care and any future imaging interpretation.

The typical candidate has moderate-to-severe knee arthritis producing daily pain, stiffness, or instability that has not responded adequately to medication, corticosteroid or hyaluronic acid injections, weight management, or structured physiotherapy.
Imaging — weight-bearing X-rays and sometimes MRI — must confirm significant cartilage loss or bone-on-bone changes that explain the functional limitation.
Partial knee replacement is appropriate when damage is confined to a single compartment and the knee's main ligaments remain intact and functional.
Pre-surgical health review covers cardiovascular and pulmonary fitness, diabetes control, and blood-clotting history. Surgery may be deferred in cases of active joint or systemic infection, severely compromised bone quality, or unstable medical conditions.
Smoking and uncontrolled blood sugar are known risk factors for slower wound healing and higher infection rates; your care team will advise on optimising these before your travel date.
Ask the hospital whether its surgical team can assess your imaging before you travel; this can reduce uncertainty on arrival.
The operation is performed under general anaesthesia or spinal anaesthesia combined with a targeted nerve block for post-operative pain control.
Total knee replacement steps:
Partial knee replacement follows the same principles but only the single damaged compartment is resurfaced, leaving healthy areas of the joint untouched.
Robotic-assisted alignment: The surgeon works from a digital model of the patient's specific anatomy. The robotic or computer-navigation system guides bone preparation in real time, helping to achieve precise implant positioning and limb alignment.
Most implants are fixed with bone cement. Soft tissues around the joint are carefully balanced to ensure smooth, stable movement through a full range of motion. Total operative time is typically one to two hours. Physiotherapy begins within the first day after surgery.

Day 1–2: The physiotherapist visits in the hospital room. You will stand and take guided steps with a walking frame. Early movement is intentional — it reduces blood clot risk and begins restoring joint range of motion.
Week 1: The care team monitors the wound, manages swelling with elevation and ice, and progressively increases walking distance. Stair practice begins when the team judges it safe.
End of week 2: Sutures or skin clips are checked and usually removed. The surgeon reviews your wound and functional progress before confirming flying clearance. Longer international flights carry an elevated blood clot (deep vein thrombosis) risk after major joint surgery, so this sign-off is taken seriously.
Travel preparation: Ask the hospital for compression stockings, written guidance on in-flight ankle exercises, hydration advice, and any blood-thinning medication your surgeon prescribes before you fly.
Discharge documents: You will receive a written rehabilitation plan, operative summary, and full implant details — make, model, and lot number — for your home physiotherapist and family doctor.
Home recovery: Ongoing physiotherapy continues for several months. Most patients walk without aids in weeks; returning to normal daily activities takes longer and depends on individual healing and consistent rehabilitation.

Costs vary by hospital and case. Ask the hospital for a written, itemised estimate before you decide.
Korea's orthopaedic surgery sector operates under Ministry of Health and Welfare regulation, with leading hospitals holding KOIHA (Korea International Healthcare Accreditation) certification and supported by KHIDI's international patient frameworks.
Major Korean orthopaedic centres offer robotic-assisted and computer-navigated joint replacement as a standard option — not a rare premium service.
Physiotherapy is integrated into the inpatient stay from day one, reflecting a clinical culture that treats post-operative mobilisation as part of the surgical outcome rather than a separate concern.
International patient departments at leading hospitals provide dedicated interpreter services and structured admission and discharge planning.
Ask the hospital whether it offers a pre-arrival review of your imaging, interpreter presence at key consultations, and a written discharge pack for your home clinical team.
Key Takeaways
Total knee replacement resurfaces all three compartments of the knee joint — the inner (medial), outer (lateral), and kneecap (patellofemoral) surfaces. Partial (unicompartmental) replacement treats only the compartment that is damaged, leaving healthy cartilage and bone untouched elsewhere. The decision is based on your weight-bearing X-rays and MRI results. Ask the hospital whether its surgical team can review your X-rays and MRI scans before you book flights.
Major joint surgery temporarily increases the risk of deep vein thrombosis (DVT) — blood clots that can form in the leg veins during long periods of immobility, such as a long-haul flight. Flying clearance is given individually by your surgeon, typically at the end of the recommended 14-day inpatient stay, after reviewing wound healing and functional progress. Travel precautions include prescribed blood-thinning medication, compression stockings, regular in-flight ankle exercises, and adequate hydration. Ask the hospital for a written, staged rehabilitation plan and operative summary to give to your physiotherapist or doctor at home, so care continues without gaps.
Ask the hospital for a written, staged rehabilitation plan and operative summary to give to your physiotherapist or doctor at home, so care continues without gaps. The home program typically runs several months, focusing on restoring range of motion, building muscle strength around the new joint, and progressing from aided to unaided walking. Most patients walk without a frame within weeks, but full recovery, including extended walking or stair climbing, takes longer and depends on consistent physiotherapy.
It does not include international flights, accommodation outside the hospital, meals not provided on the ward, or extended outpatient rehabilitation after returning home. Bilateral (both knees) surgery is quoted separately and at a higher cost.
Robotic-assisted and computer-navigated systems allow the surgeon to plan bone preparation from a digital model of the patient's specific anatomy before the operation begins. During surgery, the system guides the cutting instruments in real time, helping to achieve precise implant positioning and correct limb alignment. Accurate alignment is associated with more natural movement mechanics and longer implant function. At KOIHA-accredited Korean orthopaedic hospitals, robotic-assisted alignment is offered as a standard option rather than a rare specialist service.
Active joint infection or systemic infection must be treated and resolved before surgery can proceed. Severely compromised bone quality (for example, advanced osteoporosis) may affect implant fixation and will be assessed by the surgical team. Unstable cardiovascular or metabolic conditions require optimisation before anaesthesia is safe. Uncontrolled blood sugar and active smoking are associated with slower wound healing and higher infection rates — the team will advise on managing these before your scheduled date.
