Following knee replacement, patients experience mild to moderate pain for a few days to a few weeks, according to the American Association of Hip and Knee Surgeons. After the recuperation period, patients still have an awareness that their artificial knees are not natural due to sounds and occasional movement limitations.
The actual knee replacement takes place under anesthesia so that the patient experiences no pain. However, depending on the type of anesthesia, there may be pulling and pushing sensations, states the American Association of Hip and Knee Surgeons.
During and after recuperation, the artificial knee sometimes makes clicking or popping sounds, which produce anxiety in some patients, according to Healthline. Some patients have ongoing areas of numbness or experience slight tingling in the knee area. These sensations do not affect the function of the knee.
Areas of redness and warmness around the artificial knee are common side effects for the first year following knee replacement, and these side effects sometimes continue past the one-year mark, according to Healthline. As long as the warmness is not severe, it does not signal a problem with the joint. Icing improves the symptom. Weakness surrounding the joint is also common for the first year after surgery. Many patients are unable to kneel. A regular exercise program improves strength for better mobility.
