Robotic-arm assisted surgery for total or partial knee replacements is becoming more common for the growing number of patients suffering from pain caused by arthritis or injury — and who haven’t found relief with non-surgical treatments.

Miami Orthopedics & Sports Medicine Institute is the first institution in Miami-Dade County to invest in the Mako Robotic-Arm Assisted Technology, manufactured by Stryker. Mako has helped surgeons perform partial and knee replacements more accurately. For patients, that means preserving soft tissue, saving healthy bone, and realizing faster recoveries.

Every patient that needs a knee replacement, whether a total or partial knee, is candidate to have a robotic procedure with Mako, says Juan Carlos Suarez, M.D., orthopedic surgeon with Miami Orthopedics & Sports Medicine Institute.

“The robotic knee replacement surgery is a big advancement in the field of joint replacement because it allows us to personalize the surgery,” explains Dr. Suarez, an expert in knee and hip replacements. “And what we’re learning is that not all patients need their knee replacement done exactly the same way. But you cannot do it without accuracy and precision.”

Total or partial knee replacements using Mako starts with a CT scan that creates 3D images of a patient’s unique anatomy. Using these images, the Mako technology guides surgeons to cut what’s planned precisely for each patient. The surgeon uses the technology to evaluate bone structure, disease severity, joint alignment and the surrounding bone and tissue. This enables them to determine the optimal size, placement and alignment of the implant.

With the help of increased precision, Mako protects soft tissue and ligaments from damage. In a clinical study, Mako patients surveyed six months after surgery reported less pain and resumed normal activities sooner, compared to those who received a conventional joint replacement.

“What the robot allows you to do is precisely that. It allows you to personalize any replacement based on the specific needs of that patient, which is leading to faster recovery,” says Dr. Suarez.
