3-D technology and robotic arm enable accurately aligned implants based on each patient’s anatomy
- MakoTM Robotic-Arm Assisted Surgery System enables surgeons to replace worn out knee – and hip – joints with pinpoint precision.
- Patient-specific modeling technology and surgeon-controlled robotic arm enable more accurate alignment and placement of implants during joint replacements.
- Joint replacement procedures are personalized based on a 3-D virtual model of each patient’s unique knee anatomy.
Bountiful, UT – Surgeons at Lakeview Hospital are the first in Utah to customize total knee replacements with the help of 3-D modeling technology and a robotic arm. The Bountiful-based hospital originally implemented the MakoTM Robotic-Arm Assisted Surgery System to enable minimally invasive partial knee and total hip replacements. Stryker updated the system in March 2017 and now the hospital’s specially trained surgeons are utilizing it to totally replace knee joints with pinpoint accuracy.
”We are committed to providing the best orthopedic care in Utah, which is why we are the first in the state to offer this innovative technology to patients who need a total knee replacement,” said Troy Wood, CEO at Lakeview Hospital. “Our orthopedic specialists are truly excited about how the Mako System will benefit patients who come to our hospital for total knee and hip replacements.”
With computerized modeling technology, the Mako system provides surgeons with a virtual 3-D model of the diseased joint. With high-resolution images, surgeons can evaluate all areas of the joint prior to surgery, accurately identify diseased areas of the joint and develop unique surgical plans for each patient. During the procedure, the surgeon guides the robotic arm according to the 3-D model and more precisely replaces the painfully deteriorated joint.
Combined with the surgeons’ skills, this technology-assisted approach enables optimal alignment and more accurate positioning of the implants, which better restores the patient’s original anatomy. By selectively targeting the diseased part of the knee or hip joint, the surgeon can replace it while sparing the healthy bone and ligaments surrounding it.
“Accuracy is key to planning and performing both total knee and total hip procedures,” said Joshua Hickman, M.D. orthopedic surgeon at Lakeview Hospital. “For good patient outcomes, it is important to align and position the implants just right. With the Mako System, we can personalize partial knee and total hip replacements based on each patient’s specific anatomy and more precisely perform the procedures.”
Extremely accurate placement specific to patient’s anatomy
Stabilizing ligaments, non-arthritic cartilage and muscles are left intact
Soft tissue protection for the ligaments around the knee
Minimal blood loss and low risk of blood clots
Decreased post-operative pain
Accelerated rehabilitation and faster recoveries
An improved quality of life
How It Works
The patient undergoes a CT scan of the affected knee or hip
The Mako Surgery System generates personalized, 3-D models based on CT scans
Before the procedure, the surgeon consults the virtual 3-D model while planning the joint replacement, utilizing live motion data to adjust the position and alignment of the implants
During the procedure, the surgeon utilizes computerized navigation and the robotic arm to position the implants with pinpoint precision (within 1mm and 1 degree of the plan)
Surgeons can make adjustments to the surgical plan intraoperatively if needed
