In osteoarthritis the protective cartilage inside the joint wears away. This makes movement of affected joints difficult and painful. The intensity of osteoarthritis pain may vary from person to person and can range from mild to severe. In Rheumatoid arthritis the joints and other organs are attacked by the body’s own immune system. Normally the immune system protects human body from invaders like viruses, bacteria. In rheumatoid arthritis it becomes overactive and attacks healthy tissues. In people with autoimmune disease like RA, the persistent inflammation breaks down the joint and damages it permanently. Gout is a form of inflammatory arthritis but it does not cause body-wide inflammation like RA. In Gout, uric acid crystals are the roots of problem. Excess uric acid can form crystals in joints. This results in painful joint inflammation. Gout usually strikes in the large joint of the big toe, but can also affect other joints.

What are the solutions, if there is bone to bone contact in knee joint? (Severe osteoarthritis)

Bone to bone contact knee pain indicates severe osteoarthiritic knee. When the cartilage in the knee wears away to the point of causing bone to bone contact knee pain, diagnosis will involve moving your knee to check range of motion and signs of degeneration and injury. Your doctor will also ask you question about your medical history. This can include details of your symptoms and how long you have been experiencing them. Imaging test like x-ray, MRI, will be used to confirm a diagnosis of bone to bone contact osteoarthritis. The initial treatments of osteoarthritis are weight reduction, physiotherapy and life style modification.

What are technological advancements to make knee replacement accurate & long lasting ?

Use of advanced technology in knee replacement surgery has made this procedure more accurate and long lasting. The availability of advanced prosthetic materials provide orthopedic surgeons with options that helps increase the longevity of the prosthesis. Studies have shown well-aligned knee replacement may last longer and be more functional. This can be achieved by the use of computer navigation for knee replacement surgery. Computer assisted surgery can help the surgeon to align the patient’s bone and implants accurately which is not possible with the naked eye. It can also help in ligament balancing that insures better range of motion.

What are the risks associated with knee replacement surgery?
