Minimal Invasive Orthopaedics Athens | Dr. Michalis Sarantis | Proven Results
Finding an orthopaedic surgeon in Athens who combines academic training with a broad clinical scope is rarely straightforward. Dr. Michalis Sarantis MD, MSc is an orthopaedic surgeon based in Athens whose practice covers joint replacement, minimally invasive orthobiologic treatments, sports injuries, paediatric orthopaedics, and metabolic bone disease. He consults from his private clinic at 118D Kifissias Avenue, from Metropolitan Hospital’s Sports Medicine Department, and remotely for patients who prefer an initial online assessment. His profile on Asklepieia Health carries an Evaluated Member designation, confirming that his credentials have been reviewed through the platform’s assessment process.
Credentials and Clinical Training
Dr. Sarantis holds an MD from the National and Kapodistrian University of Athens (NKUA) and a Master of Science (MSc). He is currently a PhD Candidate at NKUA, reflecting active engagement in clinical research alongside his practice. He is a member of the Hellenic Association of Orthopaedics and Traumatology (HAOST), the national professional body for the specialty in Greece.
His clinical training included an extended period at the 4th Orthopaedic Department of KAT General Hospital in Athens — one of Greece’s primary trauma and musculoskeletal centres — where he worked from 2017 to 2022. KAT handles a high volume of complex orthopaedic cases, and training there provides exposure to a wide range of acute and elective procedures. He currently operates across two clinical settings in Athens and holds consulting availability in Volos at Elpis Clinic.
Arthroplasty and Joint Replacement
Arthroplasty — surgical joint replacement — is one of the core procedures in Dr. Sarantis’s practice. The procedure involves replacing damaged joint surfaces with prosthetic components and is most commonly applied to the knee and hip in cases of advanced osteoarthritis or other degenerative joint conditions. According to the National Health Service (NHS), knee replacement surgery typically lasts one to two hours and replaces the lower end of the thigh bone and the upper end of the shin bone with metal and plastic components, performed under general or spinal anaesthesia.
Joint replacement requires a full hospital surgical environment — appropriate anaesthesia, implant handling facilities, and post-operative monitoring infrastructure. Dr. Sarantis performs arthroplasty in a hospital setting rather than at his private clinic. Patients can view specific service information on his arthroplasty listing on Asklepieia.
Orthobiologic and Minimally Invasive Treatments
Orthobiologic treatments use biological substances — often derived from the patient’s own body — to support tissue repair and reduce inflammation in musculoskeletal conditions without open surgery. Dr. Sarantis offers the following minimally invasive orthobiologic interventions:
- Platelet-rich plasma (PRP) — the patient’s blood is drawn, platelets are concentrated via centrifugation, and the preparation is injected into the affected area
- Hyaluronic acid injections — used to supplement joint fluid and reduce friction in arthritic joints
- Mesotherapy — localised injection of compounds to support tissue recovery
- Collagen injections — used to support tendon and connective tissue repair
- Corticosteroid injections — anti-inflammatory injections for acute and chronic joint conditions
The American Academy of Orthopaedic Surgeons (AAOS) notes that PRP concentrates platelets to approximately five to ten times their normal level and has been applied to conditions including chronic tendon injuries and mild to moderate knee osteoarthritis, with associated risks described as minimal and comparable to those of corticosteroid injections. Individual suitability should be discussed with Dr. Sarantis directly. Further detail is available on his orthobiologic treatments listing on Asklepieia.
Sports Injuries, Paediatric Orthopaedics, and Additional Services
Sports-related orthopaedic injuries — including ligament tears, tendon pathology, and overuse conditions — form a significant part of Dr. Sarantis’s practice. His affiliation with Metropolitan Hospital’s Sports Medicine Department reflects this clinical focus. He also has experience in paediatric orthopaedics, covering musculoskeletal conditions in children and adolescents where growth-plate considerations and developmental factors require assessment beyond standard adult orthopaedic protocols.
Additional services include orthopaedic check-ups — structured consultations to assess joint health and identify early pathology — orthopaedic fracture management across a range of anatomical sites, and assessment and management of metabolic bone conditions including osteoporosis.
Booking Through Asklepieia Health

Frequently Asked Questions
What orthopaedic conditions does Dr. Sarantis treat?
Dr. Sarantis treats a range of musculoskeletal conditions including degenerative joint disease requiring arthroplasty, acute and chronic sports injuries, fractures, paediatric orthopaedic conditions, metabolic bone disease including osteoporosis, and conditions managed through minimally invasive orthobiologic injections such as mild to moderate knee osteoarthritis and chronic tendon pathology.
Is joint replacement surgery performed at his private clinic?
No. Arthroplasty requires a full hospital surgical environment — theatre facilities, anaesthesia, and post-operative monitoring. Dr. Sarantis performs joint replacement in a hospital setting. His private clinic on Kifissias Avenue and his sessions at Metropolitan Hospital are used for consultations, pre-operative assessments, minimally invasive treatments, and follow-up care.
What is PRP and what are the associated risks?
Platelet-rich plasma (PRP) is produced by drawing a small volume of the patient’s own blood, concentrating the platelets through centrifugation, and injecting the result into the target area. Because the preparation is derived from the patient’s own blood, the risk profile is generally low. The American Academy of Orthopaedic Surgeons describes associated risks as minimal and comparable to those of corticosteroid injections. Individual suitability should be discussed with Dr. Sarantis before proceeding.
Can I consult Dr. Sarantis online?
Yes. Online consultations are available through his Asklepieia Health profile. This suits patients outside Athens, those who want a remote initial assessment, or those for whom travel is difficult. The consultation is conducted directly with Dr. Sarantis.
Does Dr. Sarantis treat children and adolescents?
Yes. Paediatric orthopaedics is within his clinical scope. Assessment and management of musculoskeletal conditions in younger patients involves growth-related considerations that differ from adult presentations. Parents can use his Asklepieia listing to review services and request a consultation.
