Knee Replacement Surgery in India
It also known as knee arthroplasty (ARTH-row-plas-tee) — can help relieve pain and restore function in severely diseased knee joints.It is a surgical procedure wherein diseased knee is treated by removing the damaged cartilage and bone and replacing it with synthetic one. The materials used to create an artificial joint are made up of metal (titanium or cobalt chrome) and are strong and long lasting. Since they produce less friction, they are optimal for joint function The most common reason for knee replacement surgery is to repair joint damage caused by osteoarthritis or rheumatoid arthritis. People who need knee replacement surgery usually have problems walking, climbing stairs, and getting in and out of chairs. They may also experience moderate or severe knee pain at rest
There are 3 types of arthiritis
It’s the “wear and tear” that happens when your joints are overused. It usually happens with age, but it can also result from joint injuries or obesity (which puts extra stress on your joints).
Joints that bear weight — such as your knees, hips, feet, and spine – are the most common places it affects. It often comes on gradually over months or years. It causes pain in the affected joint. But people who have it don’t feel sick or have the fatigue that comes with some othertypes of arthritis. the tissue covering the bones softens and wears away, the bone began to rub against each other and leads to severe pain.
2. Rheumatoid Arthritis
It is an autoimmune disease. The immune system attacks parts of the body, especially the joints. That leads toinflammation, which can cause severe joint damage if you don’t treat it.People who have rheumatoid arthritis get lumps on their skin called rheumatoid nodules. These often form over joint areas that receive pressure, such as over knuckles, elbows, or heels.
traumatic arthritis is caused by the wearing out of a joint that has had any kind of physical injury. After a severe injury such as a fracture or dislocation, post-traumatic arthritis develops. This type of arthritis usually occurs after a serious knee injury. Knee arthritis can make it hard to do many everyday activities, such as walking or climbing stairs. It is a major cause of lost work time and a serious disability for many people.
Types of knee replacement
There are several kinds of replacement knee joint as well as different surgical methods. Taking into account the condition of your knee and your general health.
There are about the four main types of knee replacement surgery:
- total knee replacement
- unicompartmental (partial) knee replacement
- kneecap replacement (patellofemoral arthroplasty)
- complex or revision knee replacement.
Total knee replacement
The operations involve replacing the joint surfaces at the end of your thigh bone (femur) and at the top of your shin bone (tibia).
A total knee replacement may also involve replacing the under-surface of your kneecap (patella) with a smooth plastic dome
The new parts are normally cemented in place. If cement is not used then the surface of the component facing the bone is textured or coated to encourage bone to grow onto it, forming a natural bond.
Another common technique is to use a mobile plastic bearing which isn’t firmly fixed to the metal parts. This may help to reduce wear on your new joint, though it isn’t hasn’t been shown to provide better long-term results
unicompartmental (partial) knee replacement
There are three compartments of the knee – the inner (medial), the outer (lateral) and the kneecap (patellofemoral). If arthritis affects only one side of your knee – usually the inner side – it may be possible to have a half-knee replacement (sometimes called unicompartmental or partial replacement. Because this involves less interference with the knee than a total knee replacement, it usually means a quicker recovery and better function. Partial knee replacements can be carried out through a smaller cut (incision) than a total knee replacement, using techniques called reduced invasive or minimally invasive surgery. A smaller incision may further reduce the recovery time. Partial knee replacement isn’t suitable for everyone because you need to have strong, healthy ligaments within your knee. Sometimes this won’t be known until the time of surgery.
Rotating Knee Replacement
A rotating hinged total knee prosthesis may be utilized for the treatment of global instability or severe bone loss around the knee. The rotating knee replacement implants not only swing back and forth (like a hinge), but the knee can also rotate inwards and outwards (a twisting motion). Because a normal knee joint rotates a small amount, the rotating knee replacements are intended to more closely replicate normal knee moti
It’s possible to replace just the under-surface of the kneecap and its groove (the trochlea) if these are the only parts affected by arthritis. This is also called a patellofemoral replacement or patellofemoral joint arthroplasty.
Today’s implants are designed to last many years, it’s possible that at some point in the future—typically 15 to 20 years or more—your prosthetic will break or wear out. If you are overweight or you engage in high impact activities such as running or court sports, the device may fail sooner. When a knee replacement no longer functions correctly, revision surgery is often required. During this procedure, a surgeon replaces the old device with a new one.Revision surgery isn’t something to take lightly. It is more complicated than a “initial” total knee replacement (TKR) and entails many of the same risks
Cost of Knee replacement Surgery in India
The cost of Total Knee Replacement in India is quite low as compared to anywhere in the world. Even the Oxinium Knee Replacement procedure can cost up to $ 75,000 in U.S.A whereas in India, the cost is quite low
