Knee replacement with an artificial knee is a surgical process to replace the damaged sides of the knee joint to reduce disability and pain. It is performed for rheumatoid arthritis and osteoarthritis, and also for other knee and bone diseases such as psoriatic arthritis. In knee-replacement patients with a severe defect from progressive rheumatoid arthritis, osteoarthritis or trauma, the surgical procedure may be more difficult and have a higher risk factor. Osteoporosis will cause deformity, knee pain, or inflammation and but it is not a reason to do a knee replacement.
Other major reasons for pain include ligament tears, cartilage defects, and meniscus tears. Unbearable pain from osteoarthritis and rheumatoid arthritis are common in the old age. Knee replacing with artificial knee surgery can get executed as a partial or a whole knee replacement. In general, knee replacement surgery process consists of replacing the damaged or diseased joint sides of the knee with plastic and metal components molded to allow easy movement of the knee.
The knee replacing with artificial knee surgery involves extensive postoperative pain and includes important physical therapy. The recovery period for this is six weeks or longer than one to two months and may include the use of mobility helps or support like walking frames, crutches and canes to support the patient’s return to original mobility.
Risk factors and complications in knee surgery are similar to those related to every joint replacement. The most severe complication is inflammation and infection of the joint, which may occur in less than 1% of patients. Risk factors for inflammations get related to both patient and knee replacing surgical factors. There are increased risks of difficulties for overweight or obese individuals facing through total knee replacement with an artificial knee. The unhealthily overweight should get recommended to lose weight before surgical procedures start. Let’s look at some risk factors that will make this procedure more complicated.
Deep Vein Thrombosis
According to the American Academy of Orthopedic Surgeons, deep vein thrombosis in the knee is the most common risk factor for replacement surgery. There is some prevention for this problem includes periodic advancement of patient’s legs, knee exercises to increase blood circulation, support knee-highs, and medicine to thin your blood.
The medical experts at Onward Orthopedics say that Periprosthetic fractures are becoming more common in the aging patients and may occur postoperatively or intraoperative.
Loss of Motion
The legs at times cannot recover to its normal range of motion (usually it is 0–135 degrees) after total or partial knee replacement surgery. Most of this is not independent of pre-operative function. All this type of patients may gain 0–105 degrees, but the difficulty of the knee joint may occur. In some conditions, the operation of the knee under anesthetic is used to reduce post-surgical toughness. There are many implants from producers that are designed to make high-flex artificial knees, which offers a great range of motion.
In some of the knee replacement patients, the kneecap is unpreventable post-operation and displaces to the external side of the knee. It is painful and needs typically to get cured by surgery to readjust the kneecap, but this is very rare.
