Can you have an mri with a knee replacement
X-ray and mri for knee arthritis
Monday, March 18, 2019ArticleThe effects of arthroplasty on MRI At some point in their lives, many Americans would need joint replacement surgery. Joint replacement may be needed for a number of reasons, including prior injury and osteoarthritis. The most common cause for joint replacement is osteoarthritis, a degenerative type of arthritis. The surgeon and the patient must determine if the replacement joint will be ceramic or metal when they undergo this surgery, known as an arthroplasty.
Arthroplasty (joint replacement surgery) is most often performed on the hip and knee, although other joints such as the ankle and elbow may also be replaced. Surgeons replace a damaged joint with an artificial one during this procedure. A prosthesis is an artificial joint. 1 Many doctors don’t recommend arthroplasty until all other treatments have failed, even though it can relieve joint pain and improve a patient’s quality of life. 1.2
Metal, ceramic, and plastic are some of the artificial joints that can be inserted during surgery. Each alternative can be used to replace specific areas in various joints. Metal is also used in prostheses, which has implications for future health care and imaging. The prosthesis may offer relief to the patient, but if the pain returns after the surgery, further imaging and joint testing may be needed.

A strong magnetic field, radio waves, and a computer are used in magnetic resonance imaging (MRI) of the knee to provide precise images of the structures inside the joint. It’s most commonly used to diagnose or assess discomfort, fatigue, swelling, or bleeding in and around the joint. Knee MRI does not expose you to ionizing radiation and will help you assess whether or not you need surgery.
Tell your doctor if you have any health issues, recent operations, allergies, or if you think you might be pregnant. Although the magnetic field is not harmful, it has been known to cause medical devices to malfunction. Although most orthopedic implants are safe, you should always inform the technologist if you have any devices or metal in your body, especially in or near your brain, spinal cord, heart, or eyes. The rules for eating and drinking before your exam differ depending on the facility. Unless otherwise instructed, continue to take your daily medications. Remove all metal piercings and leave jewelry at home. Dress in loose-fitting, comfortable clothes. It’s possible that you’ll be asked to put on a gown. If you have claustrophobia or anxiety, you might want to request a mild sedative from your doctor before the test.

A doctor may recommend knee replacement surgery as a treatment choice, but the patient must determine whether or not to proceed. When their physicians recommend knee replacement surgery, some patients opt for it right away. Others wish to stop or delay surgery for as long as possible.
If you’re thinking of getting a knee replacement, ask yourself these three questions: What is the effect of knee pain on one’s lifestyle? Have you tried any other options? in addition What are the dangers of foregoing surgery?
– person’s perception and tolerance to pain is different. If knee pain interferes with work, socializing, sleeping, maintaining good health, or other everyday activities, knee replacement surgery may be necessary.
People who lead active lives are more likely to suffer from knee pain and seek knee replacement surgery earlier. A individual who stands for work, babysits grandchildren, and walks a pet dog, for example, may be more affected by arthritic knee pain than someone who leads a more sedentary lifestyle.

Computer-assisted, personalized knee replacements are a new choice for those with chronic knee pain that can maximize healing and functionality. Only a few hospitals in the region provide this cutting-edge orthopedic technology, and Northwestern Lake Forest Hospital is one of them.
“By combining elements of computer-assisted surgery with traditional measurements, we can produce an exact replica of the patient’s knee for the replacement,” says Tomas Nemickas, MD, a board-certified orthopedic surgeon at Northwestern Lake Forest Hospital who specializes in hip and knee replacements. “It allows a new degree of accuracy in direct size and orientation measurement.”
In a conventional knee replacement operation, the surgeon uses measuring instruments based on standard anatomical sizes and chooses from available replacement joints to get the best fit possible between the original knee’s size and alignment and the replacement knee model. During the procedure, when the patient is anesthetized, the surgeon makes changes for fit.
