Question: What is (are) Knee Replacement ?
Answer: There are many different types and designs of artificial knees. Most consist of three components: - the femoral component, which is the part that attaches to the thigh bone - the tibial component, the part that attaches to the shin bone - the patellar component, the knee cap. the femoral component, which is the part that attaches to the thigh bone the tibial component, the part that attaches to the shin bone the patellar component, the knee cap. Total and Partial Knee Replacement Knee replacement may be either total or partial/unicompartmental. In total knee replacement, as the name suggests, the entire knee joint is replaced. You will likely need a total knee replacement if you have damage to several parts of your knee. In partial/unicompartmental knee replacement, the surgeon replaces just the damaged part of the knee. You may be able to have a partial knee replacement if only one section of your knee is damaged. However, when one part is replaced, there is a chance that another part will develop arthritis, requiring further surgery. Cemented and Uncemented Joint Components Joint components may also be attached to your own bone in different ways. Most are cemented with a special joint glue into your existing bone; others rely on a process called biologic fixation to hold them in place. This means that the parts are made with a porous surface, and over time your own bone grows into the joint surface to secure them. In some cases, surgeons use a combination of cemented and uncemented parts. This is referred to as a hybrid implant. Minimally Invasive Surgery While some knee replacement surgery requires an 8- to 12-inch incision in the front of the knee, surgeons at many medical centers are now performing what is called minimally invasive surgery using incisions of 3 to 5 inches or even smaller. Because the incision is smaller, there may be less pain and a shorter recovery time. If you think you might be interested in minimally invasive surgery, speak with your surgeon.

Question: What are the complications of Knee Replacement ?
Answer: While new technology and advances in surgical techniques have greatly reduced the risks involved with knee replacements, there are still some risks you should be aware of. Two of the most common possible problems are blood clots and infection. Preventing Blood Clots Blood clots can occur in the veins of your legs after knee replacement surgery. To reduce the risk of clots, your doctor may have you elevate your leg periodically and prescribe special exercises, support hose, or blood thinners. Preventing Infections Infection can occur when bacteria enter the bloodstream from skin or urinary tract infections. To reduce the risk of infection, your doctors may prescribe antibiotics for you to take prior to your surgery and for a short time afterward. Other Complications Other complications, such as new or ongoing pain, stiffness, fracture, bleeding, or injury to the blood vessels can occur. Serious medical complications, such as heart attack or stroke, are very rare. Warning Signs To Watch For To minimize the risk of complications, it is important to recognize signs of potential problems early and contact your doctor. For example, tenderness, redness, and swelling of your calf or swelling of your thigh, ankle, calf, or foot could be warning signs of a possible blood clot. Warning signs of infection include fever or chills, tenderness and swelling of the wound, and drainage from the wound. You should call your doctor if you experience any of these symptoms. It is important to get instructions from your doctor before leaving the hospital and follow them carefully once you get home. Doing so will give you the greatest chance of a successful surgery.

Question: What is the outlook for Knee Replacement ?
Answer: Recovery from knee replacement extends long after you leave the hospital. Preparing for recovery requires learning what to expect in the days and weeks following surgery. It requires understanding what you will and wont be able to do and when. It also means arranging for social support and arranging your house to make everyday tasks easier and to help speed your recovery. Find Someone To Stay with You Because you will not be able to drive for several weeks after surgery, you will need someone to take you home from the hospital and be on hand to run errands or take you to appointments until you can drive yourself. If you live with someone, you should have them plan to stay home with you or at least stay close by, in case you need help. If you dont live with a family member or have one close by, a friend or neighbor may be able to help. Other options include staying in an extended-care facility during your recovery or hiring someone to come to your home and help you. Your hospital social worker should be able to help you make arrangements. Prepare Your Home for Your Recovery To prepare your home for your recovery, stock up on needed items before you leave for the hospital. Make sure you have plenty of non-perishable foods on hand. Prepare meals and freeze them to put in the microwave when you need an easy meal. In the first weeks after surgery, you should avoid going up and down stairs. If your bedroom is on the second floor of your home, consider moving to a downstairs bedroom temporarily or sleeping on the sofa. Set Up a Recovery Station Set up a recovery station at home. Place a sturdy chair where you plan to spend most of your time sitting during the first weeks after surgery. The chair should be 18 to 20 inches high and should have two arms and a firm seat and back. Place a foot stool in front of the chair so you can elevate your legs, and place items you will need such as the television remote control, telephone, medicine, and tissues where you can reach them easily from the chair. Place items you use every day at arms level to avoid reaching up or bending down. Ask your doctor or physical therapist about devices and tips that may make daily activities easier once you get home. Devices you may find helpful include long-handled reachers to retrieve items placed on high shelves or dropped on the floor, aprons with pockets that allow you to carry items while leaving your hands free for crutches, shower benches that let you sit while you shower, and dressing sticks to help you get dressed without bending your new knee excessively. Safeguard Against Falls Because a fall can damage your new knee, making your home a safe place is crucial. Before your surgery, look for and correct hazards, including cluttered floors, loose electrical cords, unsecured rugs, and dark hallways. Bathrooms are likely places to fall, so particular attention is needed there. A raised toilet seat can make it easier to get up and down. Grab bars in the tub can keep you steady. Textured shapes on the shower floor can minimize slipping. Gradually Increase Activity It is also important to exercise to get stronger while avoiding any activities that can damage or dislocate your new joint. Activity should include a graduated walking program (where you slowly increase the time, distance, and pace that you walk) and specific exercises several times a day to prevent scarring, restore movement, and stabilize and strengthen your new knee. Remember Follow-ups Your surgeon will let you know about follow-up visits. Even after you have healed from surgery, you will need to see your surgeon periodically for examinations and x-rays to detect any potential problems with your knee. By preparing for surgery and recovery and following your doctor's advice, you can get the greatest benefits from your new knee with the least risk of complications for many years to come.

Answer: Treatments your doctor will likely recommend before knee replacement include - exercises to strengthen the muscles around the knee and improve flexibility - weight loss, if needed, to reduce the load the knee must bear - walking aids such as canes to reduce stress on the joint - shoe inserts to improve the knees alignment - medicines to relieve pain. exercises to strengthen the muscles around the knee and improve flexibility weight loss, if needed, to reduce the load the knee must bear walking aids such as canes to reduce stress on the joint shoe inserts to improve the knees alignment medicines to relieve pain.
