Infection
One of the most serious complications of knee replacement surgery is infection. Therefore, it is important to take preventive measures. In general, knee replacement infections can be divided into early and late stages. The early stages happen within 6 weeks and are caused by the penetration of bacteria into the joint. Your doctor may treat this by administering antibiotics to cleanse the affected area. The late stages occur after 6 weeks when bacteria enter the bloodstream. It can be hard to cure this type. Normally, the doctor has to remove the whole knee to get rid of the bacteria. [2]
