The recovery time for double knee replacement surgery varies depending on the type of surgery performed, with short-term recovery lasting from several weeks to several months, according to Sutter Health. Long-term recovery lasts between three to six months. Double knee replacement surgery generally requires less in-hospital time.
Simultaneous total knee replacement involves surgery on both knees at the same time. Staged total knee replacement affects only one knee at a time, creating less stress on the body. Both types of surgery have similar recovery times, asserts the Rothman Institute. A simultaneous total knee replacement reduces the amount of time the patient spends in the hospital, and both knees have similar healing periods. Recovery usually begins once the patient wakes up from the anesthesia and begins his physical therapy routines.
During the patient's hospital stay, he is taught how to perform simple breathing and stretching exercises to improve circulation and reduce the risk of developing complications, states WebMD. After several weeks, the patient should be able to perform normal activities such as riding a bicycle or walking and bending. High-stress activities that put too much pressure on the knee joints, such as squatting and twisting the knee, should be limited. After a year, a checkup is required to determine the performance of the knee replacements.
