What is knee replacement?

In total knee replacement (TKR) surgery, portions of the knee joint that contain the worn, diseased or damaged surfaces are replaced with artificial devices. Materials used for resurfacing of the joint are not only strong and durable, they are also optimal for joint function because they produce very little friction. The new joint generally has two components: one made of metal (usually cobalt-chrome or titanium) and the other made of a plastic material (called polyethylene).

Knee replacement surgery is the most performed joint replacement surgery in the United States. At The Center for Joint Replacement, our skilled surgical teams perform total knee replacement (TKR) surgery, as well as complex knee revision, which entails reconstructive surgery relating to prior knee replacement.

How do I know if I need knee replacement surgery?

When evaluating a patient for any form of knee replacement surgery, including total joint replacement and revisions surgeries, your physician will do the following:

• Perform an assessment of indications for surgery
• Conduct a clinical examination of the knee and related areas
• Use medical imaging of the affected joints
• Provide preoperative education and planning, if replacement is recommended

Not all evaluations lead to surgery. When alternative measures can be taken to alleviate the pain and stiffness of the affected joint, we refer the patient to an appropriate orthopedist, rheumatologist or rehabilitation program.

How does knee replacement work?

A total knee replacement (TKR) is the established treatment for severe osteoarthritis and select degenerative conditions of the knee. The goals of knee replacement include restoration of a functional range of motion for walking and climbing stairs, pain-free movement, joint stability, and a return to moderate recreational activities. 

The Center for Joint Replacement’s preoperative assessment will reveal the degree of deformity and existing range of motion. If the preoperative condition is determined to be severe, the knee replacement procedure can also include complex, full knee revision surgery. A primary replacement of the knee may be defined as complex if characterized by one or more of the following conditions:

• Severe joint line deformities
• Extensive soft tissue damage
• Deformities due to previous fractures
• Replacement needed to treat acute trauma

Our highly skilled surgeons make every effort to restore a patient’s knee to khow it was before surgery and to correct any deformity that may have existed. Our surgeons take every step to minimize bone loss and maintain soft tissue balance. For the best recovery outcome, each patient is given a tailored, post-surgery rehabilitation program.
