What the robot actually is
Robotic-assisted knee replacement combines a pre-operative or intra-operative 3D model of your knee with a robotic arm or guidance system that helps execute the surgeon's plan precisely. The surgeon makes every decision — the robot constrains the tools to the planned cuts, like a sophisticated stencil. It is precision assistance, not automation.
Where robotics genuinely helps
The strongest case is personalization: robotics lets a surgeon plan implant position around your specific anatomy — including kinematic-style alignment philosophies that aim to reproduce your knee's natural motion rather than forcing every knee to one mechanical target — and then execute that plan within a millimeter or degree. It also provides live feedback on ligament balance, which traditionally relied on surgeon feel alone.
Evidence shows robotic assistance improves the precision of implant placement and may reduce soft-tissue trauma. Whether that translates into better long-term outcomes for every patient is still being studied honestly — which is why it's a tool in the toolbox, not a requirement for a great result.
What matters more than the robot
Your surgeon's judgment, experience, and volume of joint replacements matter more than any technology. A high-volume surgeon without a robot beats an occasional operator with one. Dr. Vojdani uses robotic and computer-assisted techniques where they serve the plan — and his fellowship training in adult reconstruction is what drives the plan itself.
Common Questions
Does robotic knee replacement cost more?
Patient out-of-pocket cost is typically the same — insurance reimburses knee replacement the same way regardless of robotic assistance.
Is recovery faster with robotic knee replacement?
Some studies suggest modestly less early pain and swelling, possibly from reduced soft-tissue disruption, but recovery timelines are broadly similar. Surgical technique and your rehab effort remain the biggest drivers.
