Total Knee Replacement

Whether to have total knee replacement surgery should be a cooperative decision made by you, your family physician, and your orthopedic surgeon at the Robotic Surgery Center. Ask your orthopedic surgeon about alternatives to total knee replacement (TKA).  If you are in the early stages of arthritis, you may be a good candidate for MAKOplasty partial knee replacement; an advanced robotic-arm assisted resurfacing procedure that preserves healthy bones and tissues.

Total Knee Arthritis

Arthritis disease in the entire knee

Using the iBlock system, an OMNILife Science mini robot, your orthopedic surgeon at the Robotic Surgery Center uses a computer-guided device to precisely position a cutting tool for bone cuts required for total knee replacement surgery. A real-time imaging system maps the cuts and is used to adjust the cutting tool after each cut is made. The precise nature of the cuts reduces trauma to the bone and surrounding muscle tissue while improving the alignment of the implant, which will increase the likelihood for the implant to last longer. Dr. Aram teaches the use of the iBlock system to surgeons and says, “In conventional knee replacement surgery, a rod is often inserted into the bone to act as a cutting guide.  The robotic and navigational technology we use is less invasive and enables the surgeon to make more accurate cuts, and that’s a significant advantage.”

Should You Have Total Knee Replacement Surgery?

Total knee replacement surgery, also known as total knee arthroplasty, is the removal of damaged cartilage and bone ends of the knee.  A metal alloy implant is placed on the end of the femur (thighbone) and a metal alloy and polyethylene (plastic) implant is placed on the top the tibia and underneath the kneecap. The implant then creates a new, properly functioning joint intended to prevent painful bone-on-bone contact. Depending on your individual condition, your surgeon may choose to replace all or part of your knee. Candidates for total knee replacement may suffer from:

  • Severe knee pain that limits your everyday activities, including walking, climbing stairs, and getting in and out of chairs. You may find it hard to walk more than a few blocks without significant pain and you may need to use a cane or walker.
  • Moderate or severe knee pain while resting, either day or night
  • Chronic knee inflammation and swelling that does not improve with rest or medications
  • Knee deformity or stiffness: a bowing in or out of your knee or inability to bend and straighten your knee
  • Failure to obtain pain relief from nonsteroidal anti-inflammatory drugs. These drugs may become less effective for patients with severe arthritis.
  • Failure to substantially improve with other treatments such as cortisone injections, physical therapy, other surgeries or complications from pain medications
