Mako Robotic-Arm Assisted Technology

for Partial Knee Replacement

​

Knowing what to expect from your joint replacement experience is important. Each patient is unique with individual reasons for knee pain. Our specialist can provide insight into the cause of your knee pain and help you explore the best treatment options available to you.

​

Arthritis and joint degeneration can cause pain that varies in frequency and intensity—sometimes constant, other times intermittent, occurring with movement or even after resting. Many patients first try medication or other conservative treatments for knee pain. If these options haven’t provided sufficient relief, you may be a candidate for Mako Partial Knee Replacement, which could offer lasting relief from knee pain. ​

​

How Mako Technology Works​

 

Mako Robotic-Arm Assisted Technology provides you with a personalized surgical plan based on your unique anatomy. The process begins with a CT scan of your affected knee, which is uploaded to the Mako System software to create a 3D model. This model enables precise pre-surgical planning and assists your surgeon in performing your partial knee replacement. 

​​​

​In the operating room, your surgeon follows your personalized surgical plan while preparing the bone for the implant.​ Using the Mako System, the surgeon guides the robotic arm within a defined area, ensuring it stays within planned boundaries. This approach promotes more accurate placement and alignment of your implant.

​​​​​Mako Robotic-Arm Assisted partial knee replacement is a treatment option for adults living with early to mid-stage osteoarthritis (OA) that has not yet progressed to all three compartments of the knee. Depending on the specific areas affected by arthritis, an implant may be placed in targeted compartments of the knee.

This surgery is always performed by an orthopedic surgeon who controls the robotic arm throughout the procedure. The Mako Robotic Arm doesn’t perform surgery independently; it only moves as guided by your surgeon. The Mako System also allows for real-time adjustments to your plan during surgery, ensuring optimal results.

Important Considerations for Partial Knee Replacement

 

​Who May Benefit

Robotic partial knee replacement is intended for use in individuals with joint disease resulting from degenerative and post-traumatic arthritis and for moderate knee deformities.

​

When Partial Knee Replacement May Not Be Recommended

​Partial knee replacement surgery is not appropriate for patients with certain types of infections, any mental or neuromuscular that could increase the risk of implant instability or failure, insufficient bone strength, immature skeletal development, severe knee instability, or significantly high body weight.

​

Common Side Effects of Knee Replacement Surgery​

As with any surgery, knee replacement surgery has serious risks which include, but are not limited to, peripheral neuropathies (nerve damage), circulatory compromise (including deep vein thrombosis (blood clots in the legs)), genitourinary disorders (including kidney failure), gastrointestinal disorders (including paralytic ileus (loss of intestinal movement)), vascular disorders (including thrombus (blood clots), blood loss, or changes in blood pressure or heart rhythm), bronchopulmonary disorders (including emboli, stroke or pneumonia), heart attack, and death. 

​

Implant related risks which may lead to a revision of the implant include dislocation, loosening, fracture, nerve damage, wear of the implant, metal sensitivity, osteolysis (localized progressive bone loss), and reaction to particle debris. Partial knee implants may not provide the same feel or performance characteristics experienced with a normal healthy joint. 

​

This overview is for educational purposes only. Outcomes vary, and not all patients experience the same level of activity post-surgery. The longevity of an implant depends on individual factors, and your doctor can advise on lifestyle adjustments, such as maintaining a healthy weight and avoiding high-impact activities, to extend the lifespan of the implant.

 

Schedule a consultation with Dr. Chronister to assess if robotic-arm-assisted surgery is the right choice for you.
