Dr. Chaar spent more than two decades in Belgium as a Senior Consultant Orthopedic Surgeon, serving simultaneously as a visiting surgeon across the Middle East before relocating to the UAE in 2014.

Dr. Chaar is internationally recognized for pioneering contributions to joint replacement surgery and complex hip reconstruction. He has performed more than 18,000 hip and knee replacement procedures. He developed an innovative technique for total hip replacement in patients with severe congenital hip dislocation (Crowe IV dysplasia) that enables correction of leg length discrepancies of up to 11 cm without femoral shortening osteotomy—a world-leading achievement exceeding previously reported limits. He has also developed advanced minimally invasive techniques in knee replacement surgery and introduced hip-preserving minimally invasive surgical techniques for selected young patients.
