Total Knee Replacement

Total knee replacement (TKR) surgery can be a life-changing option for men and women suffering from the debilitating effects of advanced arthritis or other trauma to the knee joint.

Introduced in 1968, knee replacement surgery has advanced significantly during the past nearly five decades, relying on advancements in technology, materials and surgical techniques to offer millions of men and women greater mobility and improved range of motion so they can lead productive, fulfilling, pain-free lives once again.

Why performs TKR?

Total knee replacement replaces a joint that’s become damaged by the effects of arthritis, which causes the cartilage on joint surfaces to slowly wear away, revealing the unprotected ends of the bones underneath. Without this protective cartilage barrier, even the slightest movement can be painful, and everyday activities like walking, climbing stairs and even standing up can be excruciating.

Severe arthritis results in decreased mobility that can take a huge toll on your quality of life that may limit you to the amount and types of activities you can perform.

Total knee replacement helps you to enjoy more active lives because it replaces damaged joints so movement is more comfortable again.

Because it’s a major surgery, TKR is performed when other, more conservative options like medication, injections, and physical therapy have failed to provide relief or when they aren’t an option.

Custom Knee Replacement

Custom knee replacements use MRI scans and x-rays to obtain precise measurements of your knee which can guide the surgeon during the knee replacement procedure. Data from the MRI and x-ray are fed into a computer, which uses special software to determine where the bone should be incised, or cut, in order to preserve as much healthy bone and ligament tissue as possible. This type of knee replacement offers patients substantial benefits over standard surgical techniques, including:

  • precise fit and alignment of the new joint
  • faster recovery
  • less blood loss
  • decreased risk of infection
  • less postoperative pain and discomfort
  • faster return to normal activities

How to perform TKR?

You will undergo physical exam and evaluation before surgery. You may require medical history and diagnostic imaging to ensure if replacement is the best option,

During the surgery, the knee joint will be carefully removed using the custom cutting guides to ensure as much healthy tissue is preserved as possible.

Hazel Atkinsons Story:

To facilitate movement, a metal joint is attached to the ends of the upper and lower leg bones and a special spacer is inserted. In some cases, the kneecap, or patella, will be resurfaced as well.

It takes about 1-2 hours to perform total knee replacement surgery under general anesthesia.

Conformis – iFit® Image to Implant Technology

 

The Conformis process starts with a patient CT scan through the hip, affected knee, and ankle. iFit® software converts the 2 dimensional CT data into a 3-dimensional model that replicates that patient’s unique and anatomical bone geometry.

In the 3D environment, iFit® recreates the patient’s natural J curves, corrected for deformity. It builds the femoral and tibial implants to match the unique size and shape of each knee. Further, it addresses common causes of patient dissatisfaction, pain, and unnatural feel.

Conformis has pioneered additive manufacturing and 3D printing technology for producing single-use, patient-specific. A patient uses positioning guide that comes pre-sterilized instead of reusable instruments that require cleaning and re-sterilization.

IFit® design and manufacturing technology enables mass-customization, a term foreign to the orthopedic industry. It customizes implants and instruments are delivered pre-sterilized unlike any knee replacement available today.

Simply put, iFit® technology put Conformis in a class of its own with an unparalleled speed of innovation.
