Partial Knee Replacement Surgery

Knee Pain and Osteoarthritis Relief

While partial knee replacements account for around 10% of knee surgeries performed, studies have shown that a greater amount of patients are candidates for the procedure. Mako Robotics has made it easier for candidates of all age groups to treat moderate arthritis using Mako-robotic methods. This is now used as a primary treatment for osteoarthritis of one or two compartments of the knee. Partial knee replacement is an alternative to total knee replacement, in this case treating patients with mild to severe arthritis on one side of their knee.

What Steps Will be Taken?

Once our specialists in Arizona have determined you are a candidate for a partial knee replacement, a CT scan of the knee is performed. From this scan, a 3D virtual model of your knee is created. Greater Phoenix Orthopedics will use this model to evaluate your unique bony anatomy and soft tissue alignment to determine the proper size and placement of your implants. During the procedure, Mako provides us feedback while removing the arthritic bone and cartilage. The Mako’s virtual boundary provides tactile and auditory cues that ensure your implants are placed based on your surgical plan.

Who Is A Candidate For Partial Knee Replacement?

Mako partial knee replacement is for people with knee pain or stiffness resulting from conditions like osteoarthritis, traumatic arthritis, rheumatoid arthritis and avascular necrosis that affects only one or two compartments of the knee. The knee is composed of 3 compartments; medial (inside), lateral (outside), and patellofemoral (under the kneecap). Each of these compartments can have isolated arthritic changes that Greater Phoenix Orthopedics can determine through x-rays and examination prior to surgery.

When Is Surgery Needed?

This procedure involves surgery that will resurface and replace the affected part of the knee. Surgery is indicated for a patient when you are no longer experiencing adequate relief with conservative treatment options like oral medications, physical therapy, bracing, and injectables. If you have arthritis or another cartilage disease affecting only one or two of your compartments, a partial knee replacement may be a good fit, and robotic surgery will be the perfect solution.
