Robots Assisting Your Joint Replacement Surgeon — It’s About Precision

To become a joint replacement surgeon, medical school graduates must complete a five-year residency. Today, most surgeons also choose to train for an additional year of fellowship. So, after five or six years of experience in performing joint replacement surgeries, how could orthopedic surgeons possibly improve upon their skills?

The answer is with robotic-arm-assisted technology.

Robotic-Arm Technology Enhances Joint Replacement Procedures

This innovative, proven technology — when employed by an experienced joint replacement surgeon — can improve knee and hip replacement surgery outcomes significantly.

Below are just some of the ways a robotic-assisted procedure can support your surgeon in your hip or knee replacement procedure.

  • Accurately plan implant size, orientation and alignment utilizing CT-derived 3-D modeling
  • Help the surgeon better understand how your natural joint flexed and extended before it became diseased
  • Help the surgeon recreate a path of motion in the replacement joint that matches the patient’s natural joint
  • Guide the orthopedic surgeon with real-time intra-operative adjustments for correct hip motion and soft-tissue balance
  • Use a smaller incision
  • Spare healthy bone
  • Minimize trauma to the surrounding tissue and undamaged joint components

When you undergo a knee or hip replacement, your orthopedic surgeon removes bone and tissue damaged by injury, inflammation or disease. With Mako™ robotic-arm-assisted technology, the surgeon can remove less bone. Then, with the assistance of the robotic arm, the doctor can place the implant with more precision.

Improving on a Long History of Joint Replacement Surgery

The concept of joint replacement is not new.

mako-robotic surgeryFor decades, orthopedic surgeons worked to perfect these procedures — without robots. According to a recent study, total knee replacement patient satisfaction is approaching 90 percent. We anticipate that, in upcoming studies that include Mako patients, satisfaction will exceed 95 percent.

The MAKOplasty hip and knee replacement technique is life-changing for many patients living with degenerative joint disease. Orthopedic surgeons use the system’s robotic arm to assist in aligning and positioning implants with more precision than ever. It makes us better surgeons, and our patients enjoy improved results.

Mako™ Robotic Technology for Hip and Knee Replacement

Accurate placement and alignment of the implant is fundamental to a successful hip or knee replacement and subsequent recovery.

A CT scan of the damaged or degenerated joint is loaded into the Mako software to produce a 3-D model of the joint. This 3-D model helps your surgeon plan the details of the procedure. Without this technology, the joint-replacement surgeon must discover and evaluate these details in the operating room, once the procedure had begun.

During surgery, the Mako system provides dynamic images and feedback that allows the doctor to turn a degenerated joint into a new one. The surgeon uses real-time data to enhance the accuracy of the procedure. This allows for precise placement of the implant, which was previously much more difficult to achieve.

In the hip replacement procedure, for example, use of the Mako system leads to a decline in the possible risk of hip dislocation a few hours, days or months after the procedure. It also decreases wear and allows the implant to last longer than might otherwise be possible.

A slight difference in leg length is also a potential risk for unilateral (one leg only) hip replacement, a phenomenon known as limb-length discrepancy. Although this rarely happens with the best specialists, it happens even less if they use the Mako system to plan and carry out a surgery.

Precision is one of the most important factors in ensuring the success of your joint replacement surgery. If the hardware fits perfectly, you’re almost certain to be pleased with your new hip or knee. Talk to your joint replacement surgeon to learn if the Mako system can offer these advantages for you.
