Understanding Total Knee Replacement
Total knee replacement is a surgery that helps many people every year. In this procedure doctors remove the hurt parts of the knee. They replace these with new pieces that do not cause pain. This can help you move better and feel less pain.
During knee surgery the damaged bone and cartilage are taken out. The surgeon replaces them with metal and plastic parts. These artificial pieces form your new joint. This makes your knee strong again.
People get joint replacement when their knees hurt too much. It happens when medicine or walking aids don’t work anymore. The goal is to make life easier and let you walk without pain.
After total knee replacement most patients have less discomfort. They also find they can do more things than before their surgery. With good care an artificial knee can last for many years.
Components of a Total Knee Replacement
In total knee replacement three main parts of the knee joint are replaced. The first is the end of the thigh bone known as the femur. Here a metal piece is fitted to cap off this bone smoothly. Next comes the top of your shinbone or tibia. A metal and plastic component provides a new flat surface.
The second part involves replacing your kneecap or patella’s surface. A plastic button usually takes its place. This helps ensure that you can bend your knee easily after surgery. These components work together to create a new functioning joint.
Lastly between these metal parts lies a spacer made from tough medical-grade plastic. It lets your newly replaced joint move freely without any bone touching another bone directly. With all these pieces in place you get back motion in your knee without pain or struggle after recovery from surgery.
Recovery and Rehabilitation
After a total knee replacement recovery starts right away. In the hospital you’ll begin simple movements to help your new knee. The first steps are often taken with a walker or crutches. Nurses and therapists will guide you on what to do.
Rehabilitation is key for getting your strength back. Physical therapy plays a big part in this stage. You’ll learn exercises that make your leg muscles stronger. It’s important to stick with these routines.
It takes time to adjust after surgery like this one. At home you must keep moving and follow the doctor’s advice closely. This helps avoid problems and speeds up healing of your joint.
Even small tasks can be part of your rehab plan every day. Walking more each week is good progress for most people after surgery. Over time doing things gets easier as the knee heals.
Physical therapy may last weeks or months depending on how fast you recover from knee replacement surgery. Your hard work during rehab helps ensure long-term success of the new joint.
Benefits of Total Knee Replacement
A total knee replacement has many benefits for those with joint pain. First it reduces or even stops the pain in your knee. Many people find they need fewer pain meds after their surgery. The relief can last for a long time often years.
Another benefit is better movement and mobility. After recovery you can walk smoother and stand longer without discomfort. This improves your ability to do daily tasks like shopping or housework.
The surgery also helps with the look and set of your leg. It corrects any bend that was caused by arthritis damage in the knee. With straighter legs you feel more balanced when walking around.
Knee replacement also brings back independence to many people’s lives. You may drive again, play sports, or enjoy walks outside after healing from surgery. Getting back these parts of life is a big reason why people choose this operation.
Lastly doing exercises becomes easier once the new joint works well. Strong legs are important for good health as we get older. This kind of operation makes staying active less hard over time.
