At Mission Hospital, we're performing total knee replacements using one of today's most advanced surgical procedures. Using infrared technology, a computer makes a model of the knee, which our orthopedic surgeons use as a map during surgery. This kind of computer-assisted navigation helps ensure precise alignment of the artificial knee. As a result, patients often benefit from restored function, improved mobility, and relief from pain.
Why Computer-assisted Navigation?
New computer-assisted navigation allows highly trained orthopedic surgeons to achieve precise positioning, sizing and alignment during total knee arthroplasty, better known as total knee replacement.
This precision was difficult to achieve in the past because each person's body is unique. A person's face has things in common with most other faces, but there are countless small differences that make that face function and look like one person and no one else. Knees are like that too, although the differences may not seem as apparent.
No Guesswork
With today's computer technology, there is no guesswork. Orthopedic surgeons can "see" in real time the mechanical axis of the leg, which is unique to each individual. It allows them to map your anatomy and customize the surgery.
By constantly referring to the mechanical axis and the patient's unique anatomy, surgeons are able to position and balance the knee more accurately.
Precise Positioning
This process usually enables them to get the knee positioned perfectly on the first try, as opposed to previous techniques, which often required several "trials."
This proper positioning should allow the maximum life of the implant to be achieved. Improper positioning of the knee replacement will lead to rapid failure and is the number one reason for an early revision surgery.
Minimally Invasive Tools
The instruments used in computer-assisted total knee replacement are much smaller than those used with traditional methods. They allow the surgeon to use a minimally invasive procedure that often shortens the recovery period.
The length of the knee incision depends on the body characteristics of the patient, and, while it is a very visible component of the procedure, it is not the most significant. The essential element is the delicate process of replacing the joint.
Referral and Insurance Information
Talk to your physician to decide if a total knee replcaement are viable surgical options for you, then ask for a referral to Mission Hospital's Orthopedic Services.
We also recommend that you check with your insurance provider before proceeding with any surgery. As a knee arthroplasty procedure, both techniques are typically covered by most Medicare-approved and private health insurers. However, some programs may require a doctor's referral for your insurance to provide coverage.
