The time it takes to fully recover from a knee replacement is typically 12 weeks, according to Healthline. However, it's extremely important that a patient should adhere to the daily goals of recovery after surgery in order to successfully recuperate within this time frame.
The crucial part of recovery starts on the very first day, when a patient makes use of the artificial knee by seeking the help of an assistive device. During the initial period, the patient should thoroughly understand the exercises suggested by the physiotherapist. By week three, the patient shows improvement in terms of movement, reports Healthline.
By week six, there is significant improvement if the patient keeps performing regular exercise. By the end of week 11, the patient can bend the knee to 115 degrees, notes Healthline. Finally, by week 13, the patient recovers completely and can also engage in light sporting activities.
