Arthritis is an inflammation of one or more of one’s joints associated with pain, swelling, and stiffness in the affected joint. The disease can spread to any part in the body, but it is particularly common in the knee.
Osteoarthritis is the most common form of arthritis in the knee joint. Arthritis occurs most often in people 50 years of age and older but may occur in younger people, too. In osteoarthritis, the cartilage in the knee joint gradually wears away as are the result of inflammatory changes in the joint. As the cartilage wears away, it becomes tattered and rough, and the protective space between the bones decreases. The outcome in rubbing of bones against each other. Hence, causing sharp pain in joints. Over time, the bones often grow thicker, and this results in more friction and more pain. Osteoarthritis develops slowly and the pain it induces worsens over time.
Rheumatoid arthritis a fatal disease that attacks multiple joints throughout the body, it usually affects the same joint on both sides of the body. That means if your right knee is hurting then your left knee is also hurting. In this type of arthritis the synovial membrane or synovial stratum which covers the knee joint begins to swell, This results in knee pain and stiffness.
Rheumatoid arthritis is an autoimmune disease. This means that the immune system attacks its own tissues. The immune system destroys normal tissue (such as cartilage and ligaments) and softens the bone, called inflammatory arthritis, the membrane around the knee joint to become thick and inflamed. Chronic inflammation damages the cartilage, causing soreness and stiffness.
Posttraumatic Arthritis is a form of arthritis that develops after an injury to any joint. The major cause of Posttraumatic Arthritis could be sports, a vehicle accident, a fall, a military injury, or any other source of physical trauma. For example, a car accident which broke your bone may damage the joint surface and lead to arthritis after the injury. Meniscal tears and ligament injuries can causes instability on the knee joint, which over time can result in arthritis.
A knee joint affected by arthritis may be painful and inflamed. Generally, the pain develops gradually over time, although sudden onset is also possible. There are other symptoms, as well:
Symptoms and medical history through a physical examination, and Imaging Tests like X-rays, magnetic resonance imaging (MRI) scan, a computed tomography (CT) scan, to determine the condition of the bone and soft tissues of your knee.

A variety of treatment options available are:
Surgery is suggested if the pain from inflammatory disease causes incapacity and isn’t mitigated with medical procedure treatment.
Partial replacement replaces only one side of the knee joint. Less bone is removed, so the incision is smaller, but it does not last as long as a total replacement. Partial knee replacement (PKR): Partial replacement replaces only one side of the knee joint. Less bone is removed, so the incision is smaller, but it does not last as long as a total replacement. Advisable to people with damage to only one part of the knee
Knee cap surgery involves the replacement of both sides of the knee joint. It is the most common procedure. The procedure is carried out with the removal of the damaged cartilage and bone, and then position the new implant, made of metal, plastic, or both, to restore the alignment and function of the knee.
Knee replacement is a kind of arthroplasty.
Arthroplasty is meant by repairing the joint and this procedure involves reconstruction and replacement of degenerated joints, using artificial body parts, or prosthetics. With a prosthesis or implant, the patient will feel less pain, and the knee will move properly.
Knee replacement surgery can help relieve pain and restore function in severely diseased knee joints. The procedure involves cutting away damaged bone and cartilage from your thighbone, shinbone, and kneecap and replacing it with an artificial joint (prosthesis/ implant) made of metal alloys, high-grade plastics, and polymers.
In determining whether a knee replacement (TKR) is right for you, an orthopedic surgeon assesses your knee’s range of motion, stability, and strength. X-rays help determine the extent of the damage. Your doctor has a variety of choices for knee replacement viz., prosthesis/knee or replacement implants and surgical techniques, considering your age, weight, activity level, knee size and shape, and overall health.
