Bilateral knee replacement is a procedure in which both the knees are operated. It is defined as the surgery to replace diseased weight-bearing surfaces of both the knees with the help of an artificial material which is made up of metal and plastic prosthesis devices. In this procedure, general or spinal anesthesia is given.
The surgeon shaves the joint cartilage at the ends of the femur and tibia and fits them prosthetic caps they are reattached to the remaining bone with specialized cement. After the surgery is completed, there will be a large dressing on the knee area. A drainage tube will be there to help drain excess fluids from the joint post surgery.
'The most common reason for a bilateral total knee replacement is severe arthritis. It causes pain and stiffness in both knees interfering with activities of daily living. Even simple activities like bending for picking something to become difficult. It is ideal for patients who have a significant deformity of both knees. This type of surgery allows the patient to walk straighter and without any pain and complications.
