Pascal KOUYOUMDJIAN - Chirurgien orthopédiste Nîmes

Born in Paris, France, Professor Kouyoumdjian completed his orthopaedic training in Montpellier and in Nîmes, and after completion of this training he spent one year studying spine surgery with Pr. Vital in Bordeaux, France. He also spent almost 1 year visiting other centers of excellence in Spine and Lower limb surgery in France (Saint Vincent de Paul Hospital, Paris).

Pr. Kouyoumdjian began his practice in Montpellier in 1991 at the University and Hospital Center of Montpellier (Pr. Bonnel, Pr. Maury, Pr. Diméglio) and at University and Hospital Center of Nîmes (Pr. Asencio), specializing exclusively in disorders of the hip and knee joint and especially in hip and knee arthroplasty navigation.

He has a specific interest in research and completed his PhD first during one year at the Ecole Nationale des arts et métiers (ENSAM), Paris, in the biomechanics unit of Pr. Lavaste (LBM), Laboratory of BioMechanics in 1998, thanks to his research on spine biomechanics and evaluation of spine deformity and its surgical correction by an optoelectronic technology (Vicon®) and in 2000 on the biochemanics evaluation of spinal instrumentation for spinal trauma. Concurrently to his surgical activity, he spends 5 years in the laboratory of INSERM U583 (Montpellier, France), working on an animal spinal cord model of compression (2003-08) and in the Unit 5587 (LCVN/L2C – University of Montpellier 2 (UM2)) depending on the CNRS (National Centre for Scientific Research), continuing this research project by the integration of the use of this model and its evaluation by in vivo specific MRI (2011-13). His (LCVN/L2C – University of Montpellier 2 UM2). Finally, his specific orientation around spine, hip, and knee surgery led him to integrate the LMGC (Laboratory of Mechanics and Civil Engineering) - CNRS UMR 5508 UM2 working first on the Intervertebral Disc Modeling (LCVN/L2C – University of Montpellier 2 (UM2)) 2013-21 and now on Robotic assistance in hip surgery.

Pascal
KOUYOUMDJIAN

A Pioneer of Modern Orthopedic Surgery and Robotics in France

Head of the Orthopedic, Trauma, and Spine Surgery Department at the Nîmes University Hospital Center, University of Montpellier and Nîmes – France, Professor Kouyoumdjian performs over 600 primary hip and knee prostheses annually and 300 revision surgeries of the lower limb prostheses in his unit. With extensive experience in spinal surgery, Professor Kouyoumdjian's current practice focuses on hip and knee prosthetic surgery. He is particularly interested in the enhanced recovery after surgery and was an early adopter of one-day surgery for hip and knee prosthetic surgeries in his unit. His area of expertise includes hip and knee revision surgery and the involvement of spinal pathology and surgeries in the implementation and revision of prostheses. He introduced robotic technology for hip and knee arthroplasties in France in 2018 at the Nîmes University Hospital Center, the first French university hospital to integrate it into its routine hip and knee prosthetic surgery practice.

With over 300 presentations, including more than 100 as an invited speaker at national and international conferences, over 70 publications in indexed journals, and numerous chapters in orthopedic manuals, Pr P. KOUYOUMDJIAN is involved as a university referent in five academic degrees in France (spinal surgery - hip and knee surgery - arthroscopic surgery - ankle and foot surgery, echo-guided surgery of the lower limb). Professor Kouyoumdjian is actively involved in several national scholarly societies (SOFCOT, SFHG, SFCR, CFCOT, National Academy of Surgery, OTSF) and international ones (AAHKS – American Association of Hip and Knee Surgery, EHS – European Hip Society).

Hip and Knee Surgery

Hip and knee prostheses play a crucial role in improving the quality of life for patients suffering from severe joint pathologies. These interventions restore mobility and comfort and significantly reduce pain.

The success of hip and knee prosthesis surgeries relies on two fundamental pillars: the precision of surgical technique and the optimization of the patient's care pathway.

Precision in Surgical Technique or Transitioning to Personalized Surgery


We are witnessing a revolution in orthopedic surgery with the emergence of increasingly personalized techniques. These advancements include :

• 3D Planning: Each hip and knee operation is meticulously planned in three dimensions, allowing for increased precision and optimal adaptation of implants to the individual anatomy of each patient.
• Global Posture Assessment: Special attention is given to evaluating the patient's overall posture. This approach ensures that the implants integrate harmoniously into the overall body dynamics, thereby reducing the risks of postoperative complications.
• Consideration of Aging: the natural progression of aging is considered to anticipate and manage potential challenges associated with implant longevity.
• Spinal Pathologies: Spinal pathologies are also integrated into the planning and implementation of interventions, ensuring comprehensive and tailored patient care.

These innovations mark a significant step towards more personalized and patient-centered medicine, offering optimized outcomes and faster recovery.

Optimization of the Care Pathway


Simultaneously, optimizing the care pathway is crucial to maximizing outcomes and accelerating recovery. This includes :

• Thorough Preoperative Assessment: Every patient undergoes a comprehensive preoperative assessment to identify specific needs and anticipate potential challenges.
• Effective Pain Management: Advanced pain management protocols are implemented before, during, and after surgery to ensure optimal comfort and pain-free recovery.
• Accelerated Recovery Instructions (ARI): Rapid recovery protocols are integrated to promote swift and efficient rehabilitation. These instructions cover all aspects of care, from preoperative preparation to postoperative follow-up.

This holistic and personalized approach ensures that each patient benefits not only from high-quality surgery but also from a care pathway optimized for swift and complete recovery.

Robotic assistance in hip and knee surgery

Revolution in Orthopedic Surgery: Robot Precision Offers Significant Advantages


Orthopedic surgery is rapidly evolving thanks to technological advancements. One of the most promising innovations is the use of robots to assist surgeons in hip and knee prosthesis placement. This personalized approach offers significant benefits for both patients and practitioners. Precision and Reproducibility : Robotic-assisted hip and knee prosthetic surgery provides unparalleled placement precision and reliable reproducibility. With this advanced technology, surgeons can customize each procedure for the most anatomically and posture-implication-adjusted fit, resulting in more precise surgical outcomes and optimized recovery.

Bone Preservation : Robot-assisted surgery enables extreme precision in bone preparation for prosthesis implantation. Unlike traditional methods, where healthy bone areas may be affected, the robot guides the surgeon for minimal excision, thus preserving maximum healthy bone tissue. This bone preservation reduces the risks of postoperative complications and may extend the prosthesis's lifespan.

Soft Tissue Preservation : In addition to bone preservation, robot-assisted surgery also allows for better preservation of surrounding soft tissues. The robot provides real-time visualization of anatomical structures, enabling the surgeon to navigate with precision while avoiding damage to soft tissues such as muscles, tendons, and ligaments. This approach reduces postoperative pain, accelerates recovery, and improves long-term outcomes.

Conclusion :

In summary, personalized robot-assisted hip and knee prosthesis surgery represents a major advancement in the field of orthopedics. By offering bone preservation and soft tissue preservation, this revolutionary technology enhances patients' quality of life and opens new possibilities for future surgical interventions.
