You can usually drink alcohol three months after a unicondylar knee replacement. Unicondylar knee replacement is a minimally invasive joint replacement procedure that is commonly used to treat osteoarthritis of the knee in the elderly. The method involves removing diseased cartilage tissue and replacing the cartilage with an artificial material, thus restoring the function of the knee joint. It is generally less invasive, with a low complication rate, and recovery usually occurs 3 months after surgery. After unicondylar knee replacement, alcohol is generally not recommended, as excessive alcohol consumption will cause a decrease in the body’s immunity, which can easily lead to wound infection. However, 3 months after the operation, the knee joint has usually recovered to normal, so you can drink alcohol in moderation, but should not drink too much, and should be in moderation. After unicondylar knee replacement, you should quit drinking alcohol as much as possible, eat a light diet, and perform rehabilitation exercises under the doctor’s guidance to restore the function of the knee joint.
