Approximately 1.1 million knee replacement surgeries are performed across the world, of which, 600,000 are solely performed across the United States. The procedure is implemented in case of advanced bone degeneration diseases, irreparable knee injury or accidental damage to the ligament, or the joint as a whole. Although there is no specific age bar for the procedure to be performed, yet most of the candidates belong to 50 years to 80 years of age who suffer from bone degeneration diseases like arthritis, or osteoarthritis. The success rate of knee replacement surgery worldwide is fairly high and exceeds 90-92% on an average. Besides, knee arthroplasty cost varies from $2000 to $49,500 and can be availed from several major countries all across the world.
Surgical procedure, that involves repairing of damage to both the knees, is termed as bilateral total knee replacement. The replacement is further distinguished into simultaneous as well as staged procedure, based on the procedure being performed on both the knees simultaneously or at a different time. The procedure involves removing the damaged or diseased portions of the knee joint, which has otherwise been affected by advanced arthritis. The portions removed from the end regions of the thigh bone and the shin bone is replaced by a prosthesis. This resurfacing thereby helps in restoring the normal functioning of the affected knee (hinge) joint.
Total knee replacement surgery is mostly performed in case of severe arthritis (both juvenile affecting the young and degenerative affecting the adults). However, it is performed mostly in patients above 50 years. One can be evaluated as a suitable candidate if the individual:
The total knee replacement cost depends on a number of factors, which are:
A bilateral knee replacement surgery is sometimes performed on both the knees in a single surgery or the surgeon may decide to operate on them individually in separate surgeries. The former case is preferred when the patient is young and the overall health is normal and maintained. In the latter case, there could be a gap of a few hours or a few days between the two surgeries.
During bilateral knee replacement surgery, you will be given general or spinal
The surgeon removes the kneecap and then the damaged or diseased parts of the knee are removed. These are replaced with a metal, plastic, or ceramic implants (as chosen by the surgeon, depending on the requirement). The implants are fixed using cemented or cementless fixation. The incision is closed with the help of stitches.
Bilateral knee replacement surgery lasts anywhere between one to three hours (is a single knee is replaced) or four to five hours (if both are replaced during the same surgery). Once the surgery is over, you are transferred to the recovery room for a few hours.
Bilateral knee replacement surgery is a major procedure and therefore, recovery may take time. You are likely to experience pain for the initial few weeks. However, it goes away gradually as you start performing physical exercises recommended by the doctor.
You should keep your wound dry and clean to prevent infection after the surgery. In addition, you should elevate your leg often for reduced pain. Talk to your surgeon if you experience redness, swelling, or inflammation around the knee.
