Dr. Gabriel B. Roby is a fellowship-trained orthopaedic surgeon specializing in hip and knee arthroplasty and orthopaedic trauma. He is recognized for his individualized approach to joint replacement. He selects alignment strategies—mechanical, kinematic, or technology-assisted—based on each patient’s anatomy, medical history, and goals. He combines this with a broad range of implants and minimally invasive techniques, including anterior hip replacement without a traction table, to optimize recovery and long-term outcomes. His expertise includes partial and total joint replacement, hip resurfacing, and complex cases requiring tailored solutions.

Dr. Roby's academic work focuses on alignment strategies in arthroplasty, with peer-reviewed publications on kinematic techniques. He is a founding member of the Personalized Arthroplasty Society and contributes to surgeon education in personalized and robotic-assisted approaches.

Dr. Roby practices at Charles-Le Moyne Hospital in Québec. He is committed to patient-centred, evidence-based care, with a focus on clear communication, education, and trust throughout the surgical journey to ensure care that is as human as it is technically excellent.
