This means the robotic surgical approach can ensure the knee replacement is positioned correctly, accounting for individual anatomical differences. The result of this surgeon-robot collaboration is a more natural knee movement post-surgery and a potential for a faster recovery.

The decision to opt for knee replacement surgery often comes after conservative treatments have been exhausted. In cases of severe knee pain and disability, robotic-assisted surgery may provide a solution where conventional surgical approaches have limitations.

Robotic knee replacement translates into less time under anesthesia, reduced tissue trauma, and a surgical procedure that’s fine-tuned to each person’s unique knee anatomy. It’s clear why many are turning to the robotic surgical approach, as it promises to revolutionize knee replacement surgery and, perhaps, the recovery thereafter.

The surgeon I reference earlier in this article, whose personal best is 23 procedures in one day, has patients in and out of the operating room in 45 minutes.
He only does the robotic portion of the surgery; he operates in a teaching hospital, so his students do all the pre and post-surgical procedures prior to and after the robotic replacement as he moves from operating room to the next operating room.

As an orthopedic physical therapist, I am always happy to see a referral from him.
I can rest assured that there is almost a 100% chance there will be no problems and the patient will have great physical therapy outcomes.
