A knee replacement, which is also called knee arthroplasty, is a surgical procedure where the patient's dysfunctional knee joint is replaced with artificial material like metal or plastic. At most times, knee replacement is performed when the patient's knee suffers from endless pain, stiffness, and loss of function. The knee is a hinge joint which is responsible for the movement between your thigh and the lower leg. The thighbone (called femur) adjoins itself to the large bone of the lower leg (called tibia) at the knee joint.
Before Knee Replacement Surgery, you are administered either general or spinal anaesthesia. During the knee replacement, the bone and cartilage from the thigh bone and shin bone area, where they meet at your knee joint, are replaced. The knee area of your thighbone is replaced with a metal implant and the knee area of your shinbone is replaced with a channelled plastic implant. Depending on how deteriorated the kneecap portion also is, a plastic "button" may also be added under the kneecap surface. The knee replacement surgery provides a smooth surface to the knee joint so that it can move and bend more freely with lesser or no pain at all. The artificial components used in knee replacement surgery are called prosthesis.

• Swelling around the knee joint area
Depending on the condition of your knees, whether one or both knees are dysfunctional, the surgeon may conduct one of the following surgeries for your knee replacement:
• Unilateral Knee Replacement Surgery: The diseased or damaged joint of a single knee is removed and replaced with a prosthesis. Unilateral Knee Replacement Surgery can be advised to a patient from any age group depending upon the magnitude of pain and immobility.
• Bilateral Knee Replacement Surgery: Bilateral knee replacement is surgery conducted where both your knees are replaced at the same time. The advantage of this surgery is that you get both your knees replaced in a single surgery process without having to come again. However, you may take a little longer to recover as both knees are sensitive post surgery.
• Partial Knee Replacement Surgery: This surgery replaces only that part of your knee that’s damaged. Hence, you may enjoy the advantage to the partial knee replacement surgery since that it requires a smaller incision as well as less bone and blood loss.
• Total Knee Replacement Surgery: In total knee replacement surgery, the whole knee joint is removed and replaced with an artificial/prosthetic knee joint. This surgery also requires a longer time for recovery.

• Oxinium oxidized zirconium
• Zirconium Alloy
The most common side effects or complications that may arise post the Knee Replacement Surgeries are:
• Dislocation of the knee joint (partial or complete)
• Formation of blood clot above or below the knee (treated with medicines)
• Pain with initial movement.
After your knee replacement surgery, as a patient, you would be expected to spend about 3-5 days at the hospital. Usually, before you leave the operating room, your knee may be cradled in a passive motion machine, and medical staff will monitor the bending in and straightening out limits of your knee. Immediately after the Knee Replacement Surgery, you might begin weight training as a therapy for your replaced knees. You would be also told to do frequent breathing exercises and gradually increase your activity level. It generally takes the knee replacement patients about 10-12 weeks to complete the rehab process and about 6-10 months to completely get back to normal movement.
The success rate for knee replacement surgery is very high. 9 out of 10 people experience immediate pain relief post the knee replacement surgery while 95% report complete satisfaction with the surgical procedure. In terms of longevity, 90% of the knee replacement prosthetics last up to 10 years and 80% remain in good condition even after 20 years.
Knee Replacement Surgery cost may vary across the world. Where countries like USA, UK, Canada may provide surgeries at expensive costs, countries like India are more cost effective and affordable for getting Knee Replacement Surgery with the same quality and brand.
