The joints of our body are critical for our movement and everyday activities, and among them the knee joint is one of the strongest and most important. Wear and tear, illness, or injury can damage the cartilage around your knee joint and hinder your movement.
Total knee replacement surgery or knee arthroplasty should be considered for those patients whose knee joints have been damaged by either progressive arthritis, trauma, or other rare destructive diseases of the joint. Such patients suffer from severe knee pain, swelling and even bowing of the leg which in turn limits the everyday activities. During knee replacement surgery, the surgeon takes damaged cartilage and a part of the bone out of the knee joint and replaces them with an artificial joint (prosthesis) made of metal alloys, high-grade plastics and polymers. A plastic spacer is placed between the prosthesis which ensures smooth movement of the new joint.
Patients should have a discussion with an expert doctor on the risks and benefits before making decision about knee replacement. Post surgery, it is recommended to be active by moving around your house, taking walks, and doing the exercises as suggested by your physical therapist as too much rest can slow your recovery down. You can expect long-lasting results by following your doctor's guidelines as most knee replacements have good prognosis and lasts for an average of 20 years.
