Total Knee Replacement BL

Knee replacement, also known as knee arthroplasty, is a surgical procedure that replaces the weight-bearing surfaces of the knee joint to relieve pain and disability. It is most commonly used when conservative measures fail to alleviate joint pain, as well as for other knee diseases like rheumatoid arthritis and psoriatic arthritis. The procedure may be more challenging and risky in individuals with significant deformity caused by advanced rheumatoid arthritis, trauma, or long-term osteoarthritis. Osteoporosis does not usually cause discomfort, deformity, or inflammation in the knees, and it is not a rationale for knee replacement.

Disease Overview:

Severe arthritis

Chronic discomfort, inability to do everyday chores, and difficulty walking or climbing stairs are all symptoms of severe arthritis. Arthritis can result in long-term joint abnormalities. Although some of these alterations are obvious, such as knobby finger joints, the damage is generally only detectable on X-ray.

Rheumatoid arthritis (RA) is the most debilitating kind of arthritis. Despite the fact that they both belong under the "arthritis" banner and have some similarities, these illnesses are very different.

Rest, occupational or physical therapy, hot or cold compresses, joint protection, exercise, medicines, and, in certain cases, surgery to rectify joint damage are all options for treating arthritis. One or more of these may be part of your treatment strategy.

Disease Signs and Symptoms:

Severe arthritis symptoms

• Pain.
• Stiffness.
• Swelling.
• Redness.
• Range of motion has been reduced.

Disease Causes:

Severe Arthritis can be caused by a variety of factors, including:

• Overuse of a joint causes wear and tear.
• Age (OA is most common in adults over age 50)
• injuries.
• obesity.
• Autoimmune conditions.
• Genes or a family tree
• muscle wasting

Disease Diagnosis:

Doctors examine your joints for swelling, redness, and warmth during the physical exam. They'll also want to check how well your joints can move.

Tests in the lab

Different types of bodily fluids can be analysed to determine the type of arthritis you have. Blood, urine, and joint fluid are all regularly tested fluids. Doctors wash and numb the region before withdrawing a sample of joint fluid using a needle inserted into the joint cavity.

Imaging

These tests might uncover issues that are causing your discomfort within the joint. Here are several examples:

X-rays. X-rays are a type of radiography that uses low doses of radiation to see bone and can reveal cartilage loss, bone deterioration, and bone spurs. X-rays may not detect early arthritic damage, although they are frequently used to monitor disease development.

Tomography using a computer (CT). CT scanners use a combination of X-rays from various angles to provide cross-sectional images of inside structures. CT scans can see both the bone and the soft tissues around it.

Magnetic resonance imaging (MRI) is a type of imaging that (MRI). MRIs provide more detailed cross-sectional pictures of soft tissues such as cartilage, tendons, and ligaments by combining radio waves with a strong magnetic field.

Ultrasound. High-frequency sound waves are used to imaging soft tissues, cartilage, and fluid-containing structures around joints with this method (bursae).

Ultrasound can also be used to guide the positioning of needles for extracting joint fluid or injecting drugs into the joint.
