Knee replacement surgery is done when the knee is severely damaged by arthritis, injury, or osteoarthritis. People who undergo surgery usually have problems in walking, climbing stairs, sitting and getting out of the chair, some may also have severe pain even while taking rest, if the knee is often swollen, if your knee has other problems, when all other therapies and medication haven’t worked. This surgery is one of the most common bone surgeries in the country.
Osteoarthritis is also known as wear and tear arthritis, it is caused when the cartilage which protects the ends of your bones gradually wears away. This condition causes pain and stiffness and increases over time. It develops slowly and mostly occurs during middle age. There is no permanent cure for osteoarthritis, but there are many treatments available to manage the symptoms such as pain, stiffness, and swelling, improving joint mobility and flexibility, weight management, good exercise. You may also follow alternative natural therapies to reduce symptoms by taking good nutritional supplements, acupuncture or acupressure, massage, hydrotherapy.
Rheumatoid Arthritis is a chronic autoimmune disease. It affects multiple joints throughout the body. For some, it can damage skin, eyes, lungs, heart and blood vessels. This occurs when your immune system attacks your own body tissues. The inflammation caused due to this leads to bone erosion and joint deformity. There is no cure for rheumatoid arthritis, medications and physiotherapy will help to reduce the symptoms. The early signs of rheumatoid arthritis are fatigue, joint pain, joint tenderness, swelling in the joints, joint redness, stiffness, joint warmth, limping, joint deformity, loss of movement in the joints, fever, polyarthritis.
Severe knee Deformity is caused due to arthritis, previous osteotomy, fracture malunion, congenital deformities, and also due to metabolic bone diseases. If you have RA (rheumatoid arthritis), joint deformities are the symptoms that say your disease is not under control. RA medications can help to prevent or stop the damage that leads to joint deformity. There are two types of knee malalignment - Valgus deformity and Varus deformity.
Valgus deformity makes the knee to bow inward, giving a knock-kneed appearance and gives extra pressure on the outer compartment of the knee joint. Due to this condition the person cannot touch the ankles together when their knees are together.
Varus deformity makes the knee bow outward, which looks like bow-legged appearance and puts pressure on the inner compartment of the knee joint. The person cannot touch the knees together when the ankles are together.
Wearing of a joint happens naturally as you get older; it is common to experience pain when you climb stairs, standing or while exercising. Your body is not as fit as it was in your younger years. The cartilage naturally deteriorates and causes soreness, the smooth tissue which cushions joints and helps them to move slowly disappears with age. The natural shock absorbers of the body are wearing out due to which you may lose muscle tone and bone strength. The shoulder is the most complex joints in the body, a rotator cuff is a group of muscles and tendons that helps you to lift and rotate your shoulder. Arthritis and rotator cuff tears are increasing in the majority of people after the age of 40. By giving excessive work to your shoulder beyond the capacity repetitively can lead to more advanced rotator cuff disease at an earlier age.
A total knee replacement is one of the best procedures for arthritis. As the procedures are increasing with an aging population, usage of computer navigation provides a more reliable source of intraoperative measurement and corrections of deformity. With the help of computer- assisted knee replacement- incisions are made smaller, soft tissue dissection can be kept less invasive, a great protection of the muscle and tendon during surgery. Computer-assisted navigation is very helpful in those difficult situations where accurate alignment remains crucial but traditional instrumentation is not applicable.
Joint replacement with precision – computer-aided navigation technology is the latest tool which helps the surgeons to perform the joint replacement with complete accuracy and avoids human errors during surgery, it provides visual information about the accuracy of the bone cuts, implant positioning, ligament balancing, final alignment of the limb. The patients will benefit from computer navigation technology for joint replacement – no human errors, maximizes the longevity of implant, minimizes blood loss and pulmonary embolism, quick recovery, it can be done for patients who have implants previously such as implants in bones, thigh bone deformity, severely osteoporotic bones, obese patients.
