What is a Knee Joint?
The knee joint is among the strongest, largest and most complex joints of the body. Whenever you walk, sit, squat, turn around, drive or perform many other seemingly simple movements, you are depending on the knee for support and mobility. When your knee is healthy, you may take it for granted, not giving a thought about the job it does for you. But once it starts to become painful, stiff, and you are forced to restrict certain activities, you may come to realize how much freedom of movement means to you.Fortunately, today’s advanced medical technology makes it possible to replace the knee joint with an artificial one that reduces pain, allows you to strengthen your legs, and improves your quality of life. Knee replacement is a procedure commonly performed throughout the world, and one that offers an outstanding rate of success. In this section, we will discuss how your knee works, how arthritis causes your pain and the knee replacement surgery you will have. We will also help you make preparations for the upcoming surgery and outline what you can expect every step of the way.
How You’re Knee Joint Functions?
The healthy knee.
The healthy knee joint is a remarkable mechanism. It is formed by the bottom end of the femur (thigh bone), the top end of the tibia (shin bone) and the patella (knee cap). A healthy knee joint has cartilage between the bones that acts as padding. This padding helps assure a gliding movement of the knee that is both effortless and smooth. The healthy knee joint also has a joint capsule, which houses the synovial membrane. This membrane produces lubricating fluid, which contributes to the smooth movement of the knee. The human knee is designed to withstand a lifetime of stressful activity. However, sometimes arthritis intrudes, interfering with the knee’s ability to cushion the body from stress, and eventually causing the pain that dramatically erodes your quality of life.
Pre-operative measures for Total Knee Replacement Surgery:
Total knee replacement surgery is an elective procedure. Along with your doctor, you will decide when the time is right for this surgery. Your doctor has more than likely treated your condition with plain medications, anti-inflammatory drugs or perhaps even minor surgery. But now the pain has become severe. Even staying off your feet doesn’t help. You cannot sleep at night because of the discomfort. You are probably the best judge of when you will finally need total knee replacement surgery. When the pain becomes so chronic that even medication does not seem to help, you are probably ready to consider surgery. Take the four essential steps that will help you get into shape before knee replacement surgery.
»Commit to the success of your surgery:
Working as a team, you, your physician and your family must adopt a positive attitude toward the success of your surgery. Together, you will gain a clear understanding of the common goals and expectations of the procedure.
»Lose excess weight:
Because excess weight causes strain to be placed on already-damaged joints, losing weight is one of the best ways to improve the condition of your knee and optimize surgical results. Remember to seek your doctor’s advice before beginning your weight loss program.
»Start a physician- approved, low-impact exercise plan.
After a comprehensive assessment of your condition, your physician or physical therapist may recommend a low-impact exercise plan that will strengthen your knee without creating further damage. Do not attempt an exercise program without consulting your physician!
»Stop smoking.
If you have not already done so, it is suggested that you stop smoking. This will be good for you during and after surgery.

The surgical aspects have been fine-tuned, the chances for a successful outcome are excellent.In total knee replacement (also known as total knee arthroplasty, or TKA), the joint’s bone-end surfaces are resurfaced with man-made materials. In total knee arthroplasty, the implant (prosthesis) design may vary according to your needs, but the most common implant consists of three component parts. The patella, or kneecap, is made of high-density polyethylene, which offers tremendous strength and durability. The femoral section, or thighbone, is metal, while the tibia, or shinbone, is made of high-density polyethylene and may be supported by a metal tray.
