Knee is the foremost joint and a major ‘weight-bearing’ point in the human body. Knees play a vital role in all the body movement as well as helps support body weight. It’s no doubt that a healthy and strong knee is requisite for an active lifestyle.
However, injuries, worn out cartilage or other medical conditions like arthritis or osteoarthritis can cause inflammation, pain and restrict knee flexibility. Knee replacement surgery (knee arthroplasty) is one of the most recommended surgical solutions that can help relieve pain and restore functions of severely diseased knee joints by replacing it with artificial materials.
There are two types of Knee replacement surgeries; Total knee replacement and partial knee replacement.
Total Knee Replacement involves the surgically removing ailing cartilage and bone particles from the knee area, knee cap, shin bone and thigh bone, and substitutes them with artificial joints made of metal alloys, high-grade plastics or polymers. In most of the cases, total knee replacement surgery is suggested for patient who undergoes severe knee pain or stiffness, knee pain even during sitting or lying down, chronic inflammation or swelling and knee deformities (a bowing in or out of the knee) among the other reasons.
Partial Knee Replacement is recommended for patients with arthritis limited to one area of the knee. The procedure rematerializes worn-out surfaces of the knee with artificial components made of metal alloys, high-grade plastics or polymers. As the circumference of the affected area is smaller comparing to total knee replacement, the surgery involves only small implants and incisions.
Though knee replacement surgeries are safe and involve less risk factors, there are still chances for infections. Such infections are caused either due to lack of proper post-surgical care or surgical complications. These post-surgery health issues may include blood clots, damage to the blood vessels surrounding the knee area, a problem with the implant, or persistent pain.
