A total knee replacement is the surgical removal of the entire knee joint and replacement with an artificial joint called a prosthesis. Your knee joint is formed where your thigh bone (femur) and your shin bone (tibia) meet. It is the largest joint in your body and also contains ligaments, tendons, cartilage, the kneecap (patella), and lubricating fluid. Total knee replacement can help restore pain-free range of motion and full function in a diseased knee joint.
A total knee replacement is a common but major surgery with serious risks and potential complications. You may have less invasive treatment options. Consider getting a second opinion about all of your treatment choices before having a total knee replacement.
If you don’t get an alignment on your car after putting on new tires, you’ll eventually see uneven wear and tear, possibly even tire failure. The same idea applies to your knee replacement.
Positioning and alignment are crucial to the overall performance of your implant. Researchers have found that even a misalignment as slight as three degrees can lead to uneven wear, instability and increased risk of revision surgery following knee replacement. That’s why positioning and placement play such an important role in the success of your implant.
We collaborate with advanced imaging centers and leading orthopaedic manufacturers to produce a custom cutting guide for the total knee.
Here are the steps to producing your custom surgical instruments:
A CT scan is taken of your leg at your local hospital or advanced imaging center.
Your scan files are sent to the orthopaedic manufacturer, where a special engineering team work with Dr. Alden to develop a 3-D model and surgical alignment plan for your surgery.
The structure of your knee is digitized and a 3D printer creates your personalized surgery guides.
Your custom guides are delivered sterile to the operating room prior to your surgery. During surgery, Dr Alden will confirm the accuracy of the blocks with specialized instrumentation and complete your new total knee.
