Mount Sinai Hospital was the first in Canada to perform a partial knee replacement using the VELYS™ Robotic-Assisted Solution.

Dr. Jesse Wolfstadt successfully completed the procedure using the Johnson & Johnson MedTech robotic platform. He is the Head of the Granovsky Gluskin Division of Orthopaedics at Mount Sinai Hospital.

“The VELYS™ robot allows us to enhance surgical precision and balance the knee before making a single bone cut,” said Dr. Wolfstadt. “Ideally, this will lead to less risk of implant failure and better long-term outcomes for our patients. This is especially true in procedures as delicate as a partial knee replacement.”

Partial knee replacements are generally higher risk because of the complexity of the anatomy and the need for precise cuts. By improving precision, robotic-assisted procedures may minimize complications and shorten recovery time, improving the patient experience.

Mount Sinai Hospital’s investment in robotic innovation doesn’t end with orthopaedics. Robotics are already transforming treatment in gynaecology, sarcoma, and head and neck surgery. They are also being trialed in fetal surgery at the Ontario Fetal Centre using the Da Vinci Xi Robotic Surgical System. Plans are underway to expand robotics use in general and cancer surgery.

The addition of the robotics suite was one of the many advancements of Renew Sinai, the largest and most ambitious redevelopment in the hospital’s history.
