Knee replacement or arthroplasty is utilized for conditions such as arthritis that require extensive rebuilding of the knee joint due to degenerative changes that causes painful bone-on-bone contact. It is typically used in older patients that have unsuccessfully tried conservative treatment methods to treat painful arthritic conditions.
Is anyone with knee joint issues a good candidate for partial knee replacement?
No, partial knee replacements are only a good option for select patients with osteoarthritis in which damage is limited to specific compartments of their knees. I primarily see older patients with long-term arthritis that has caused too much degeneration for partial knee replacement to be a viable choice.
What technologies do you use when doing total knee replacements?
I currently use Medacta™ technology which enables a patient to receive a state-of-the-art, custom-fit knee replacement. X-rays, CT scans, MRI, and a 3-D image of the joint are transferred to a computer, which creates the high-tech knee replacement using CAD software. This greatly reduces the primary risk of total knee replacement surgery, which is loosening of the implant.
What circumstances require revision knee replacements?
Total knee replacement is one of the most successful procedures in medicine, but sometimes revision surgery is needed. While rare, an implant can fail due to improper placement or malfunctioning of the mechanism. The prosthesis might loosen from the bone and parts of the implant can also wear out or break. Revision surgery may also be required due to infection, continued pain, knee stiffness, or instability of the mechanical components.
