Joint Replacement Surgery

Knee Replacement Surgery

We offer traditional and robotic knee replacement surgery, including:

  • Total knee replacement. Your surgeon removes diseased bone and cartilage from the bottom of your thigh and the top of your shin bone, and replaces them with metal or plastic implants.
  • Partial knee replacement. We replace part of the knee with artificial parts, but leave the rest of the joint intact.

If you prefer a robotic approach and your insurance covers it, we can perform both partial and total knee replacements using Mako technology.  

Hip Replacement Surgery

Our orthopedic surgeons offer traditional, minimally invasive and robotic hip replacement. Our areas of expertise include:

  • Total hip replacement. Your surgeon removes the top of your thigh bone — along with the “socket” portion of your pelvis — and replaces them with metal or ceramic parts (implants). 
  • Anterior hip replacement. This is a minimally invasive alternative to traditional total hip replacement. We make a 3- to 4-inch incision at the front of your hip, instead of an 8- to 12-inch incision on the side or back of your hip.  
  • Hip resurfacing (partial hip replacement). We shave just a few millimeters of bone from the top of your thigh and cap it with metal.

For patients who are interested and qualify, we can also perform total hip replacements using Mako® robotic technology. This minimally invasive approach uses planning software and a surgeon-controlled robotic arm. It enhances implant placement and helps preserve healthy bone.

Joint Replacement Surgery Differences

How Mako SmartRobotics™ works

Mako SmartRobotics™ is an innovative solution for many suffering from painful arthritis of the knee or hip. Mako uses 3D CT-based planning software so your surgeon can know more about your anatomy to create a personalized joint replacement surgical plan. This 3D model is used to preplan and assist your surgeon in performing your joint replacement procedure.

In the operating room, your surgeon follows your personalized surgical plan while preparing the bone for the implant. The surgeon guides Mako’s robotic arm within the predefined area, and Mako’s AccuStop™ technology helps the surgeon stay within the planned boundaries that were defined when the personalized preoperative plan was created. By guiding your doctor during surgery, Mako’s AccuStop™ technology allows your surgeon to cut less by cutting precisely what’s planned1-3 to help protect your healthy bone.4-8

It’s important to understand that the surgery is performed by an orthopaedic surgeon, who guides Mako’s robotic arm during the surgery to position the implant in the knee and hip joints. Mako SmartRobotics™ does not perform surgery, make decisions on its own or move without the surgeon guiding it. Mako SmartRobotics™ also allows your surgeon to make adjustments to your plan during surgery as needed.

Total knee vs. partial knee replacement

Based on the severity of the arthritis in the knee, total or partial knee replacement may be recommended by a surgeon. Both procedures involve the orthopedic surgeon guiding Mako’s robotic arm to remove diseased bone and cartilage.

Mako SmartRobotics™ for Partial Knee replacement is a treatment option for adults living with early- to midstage osteoarthritis (OA) that has not yet progressed to all three compartments of the knee. Depending on where the arthritis affects the knee, patients may have an implant inserted in any of the following areas:

  • In a unicondylar knee replacement, only one area (or compartment) of the joint is replaced.
  • A patellofemoral knee replacement replaces the kneecap (or patella) and the grove at the lower end of the thighbone (or femur).
  • A bicompartmental knee replacement affects two compartments of the knee – the inside (medial) and knee cap.
  • In comparison, Mako SmartRobotics™ for Total Knee replacement is a treatment option for adults living with mid- to late-stage osteoarthritis of the knee. With a Mako Total Knee replacement, the entire knee joint is replaced, and the surgeon inserts a Triathlon Total Knee implant. With over a decade of clinical history, Triathlon knee replacements are different than traditional knee replacements because they are designed to work with the body to promote natural-like circular motion.9-11
  • Mako SmartRobotics™ for Total Hip replacement is intended for patients who suffer from noninflammatory or inflammatory degenerative joint disease (DJD). Some forms of DJD include osteoarthritis (OA), post-traumatic arthritis, rheumatoid arthritis (RA), avascular necrosis (AVN) and hip dysplasia.
