Robotic and computer-assisted technology has changed the way total hip replacement is planned and performed. This page explains what robotic hip replacement involves, how it compares with modern minimally invasive approaches such as the ASI technique, and what patients considering hip surgery in Greece should know before deciding.
In a robotic-assisted total hip replacement, a pre-operative CT scan is used to build a three-dimensional model of the patient’s hip. On that model the surgeon plans implant size, the inclination and anteversion of the acetabular cup, femoral offset and leg length. During surgery a robotic arm or a navigation system guides bone preparation and component placement so the pre-operative plan is reproduced accurately. The surgeon performs every step of the operation; the system does not operate independently.
Most long-term problems after hip replacement can be traced back to component position. A cup placed outside the safe zone increases the risk of dislocation and edge loading of the bearing surface. Incorrect femoral offset changes the tension of the abductor muscles and can cause a limp. Leg-length discrepancy is one of the most common patient complaints after hip surgery. Accurate, reproducible positioning is therefore not a cosmetic detail: it directly affects stability, function and how long the implant lasts.
Robotic guidance is one route to accuracy. The ASI (Anterior Supine Intermuscular) technique is another, and the two share the same goal. In ASI the hip is reached through the natural interval between muscles, with the patient supine, so no muscle or tendon is cut. Because the patient lies on the back, intraoperative fluoroscopy can be used to check cup position, offset and leg length against the opposite hip in real time. The result is precise component placement combined with minimal soft-tissue damage, which is what allows patients to stand and walk within hours of surgery.
Candidates for total hip replacement are patients with advanced hip disease — osteoarthritis, avascular necrosis of the femoral head, dysplasia, inflammatory arthritis or fracture sequelae — whose pain persists despite conservative treatment and who are limited in walking, sleeping or daily activities. Age alone is not a contraindication. The decision is based on symptoms, imaging, bone quality and general health, and is always made after a full clinical assessment.
With a minimally invasive approach and a fast-track protocol, most patients are mobilised with a frame or crutches on the day of surgery and leave hospital within two to four days. Walking aids are usually abandoned within two to four weeks, driving resumes at around four weeks, and desk work at three to six weeks. Full recovery, including strength and endurance, continues for three to six months. Individual timelines vary with age, fitness and the condition of the hip before surgery.
There is no single price. The final cost depends on the implant chosen, the hospital and type of room, length of stay, anaesthesia, the surgical team, imaging and physiotherapy, and on whether the patient is covered by Greek public insurance, a private policy or is self-funding. International patients should also budget for accommodation and follow-up. A personalised written estimate is provided after the clinical assessment — please contact the practice for a quote for your case.
International patients are assessed remotely first, on the basis of recent X-rays and an MRI or CT where indicated. If surgery is appropriate, the operative date, hospital stay and rehabilitation plan are arranged in advance, so that the time spent in Greece is kept short and predictable.
