About

Dr. Alexandre Benny is a board-certified Orthopedic Surgeon specializing in hip and knee arthroplasty (joint replacement) and complex lower-limb reconstruction. He is known for pairing advanced implant strategies with modern surgical precision tools— including robotics and surgical navigation—to optimize alignment, stability, and long-term outcomes. Dr. Benny completed his orthopedic surgery training at the Université de Sherbrooke, followed by advanced subspecialty training in complex lower-extremity reconstruction at Mount Sinai Hospital (Toronto), one of Canada’s leading centers for joint reconstruction.

Hip Surgery

  • Total Hip Replacement (THA) for osteoarthritis and degenerative hip disease

    • Dual mobility systems (to reduce dislocation risk in select patients)
    • Large-diameter femoral heads (when appropriate for stability and motion)

Knee Surgery

  • Total Knee Replacement (TKA) and joint reconstruction for advanced arthritis
  • Alignment strategies tailored to the patient, including personalized alignment concepts designed to improve natural function and satisfaction

Advanced Techniques & Technology

  • Minimally invasive approaches (case-dependent) to reduce tissue trauma
  • Robotic-assisted surgery (as indicated and available)
  • Computer-assisted navigation to enhance precision in component placement and alignment

Complex Reconstruction

He began his practice in 2018 at the CIUSSS du Centre-Sud-de-l’Île-de-Montréal, where he served as head of the orthopedic department at Notre-Dame Hospital for five years. During his tenure, he contributed to the implementation of the Enhanced Recovery After Surgery (ERAS) protocol, promoting better rehabilitation and reducing post-operative complications. For the past three years, he has been practicing at Maisonneuve-Rosemont Hospital (CIUSSS de l’Est-de-l’Île-de-Montréal), a Canadian reference center for hip and knee replacement.
