4 Your Health: Knee replacement using robot technology

Posted: Updated:

Tucson- Replacing a hip or a knee has become pretty common these days but new techniques are not. An orthopedic surgical center in Tucson is now using robot technology to make knee replacement a very exact science.

Melissa Anderson has had both her knees replaced.  The surgeries were performed by Dr. Russell Cohen at the Tucson Orthopedic Institute.  But for the second procedure Dr. Cohen, utilized the Mako robotic-arm. 

"This way we can put the knee in exactly the right position", said Dr. Cohen, "For any patients anatomy and then the robot actually comes in and makes those cuts at exactly the locations for the boney cuts to be made.

Dr. Cohen said before, total knee replacement surgery involved the surgeon making those boney cuts manually. Now, with the robotic arm, the cuts can be made with an accuracy never seen before. The result is a better fit for the replacement device and faster recovery time...

"The patients seem to have much less discomfort when they start to move their knee", Dr. Cohen said, "I think it has to do with the soft tissue conflict that we normally create with manual knees, so you come in and people seem to be able to move their knee in a much calmer and smoother fashion.

Melissa Anderson said her recovery time was vastly different compared to her first knee replacement.

"I was out of physical therapy in 4 weeks, I was dancing in 2 months", said Anderson, "It was just like my old knee, it doesn't move around, it's just like my old knee.
