After surgery, vital signs and sensation in the lower extremities are observed and checked by the nursing staff and documented for the physician. Antibiotics are administered according to the physicians preference to reduce the risk of infection.
Once you've had knee replacement surgery and completed rehab, your knee should have a range of motion of 100-120 degrees, sufficient for all your daily tasks such as walking and climbing stairs.
Thanks to your new knee, you will be able to do many of the activities you did before your knee surgery, but with little or no pain. Most people with total knees can do recreational walking, swimming, golf, driving, light hiking, recreational biking, ballroom dancing, and stair climbing without difficulty.
Even though your activity level is likely to increase, a knee replacement surgery means that high-demand or high-impact activities must be avoided. You should definitely avoid running or jogging, contact sports, jumping sports, and high impact aerobics.
You should also try to avoid vigorous walking or hiking, skiing, tennis, repetitive lifting, and repetitive aerobic stair climbing. The safest aerobic exercise is biking (stationary or traditional), because it places very little stress on the knee joint.
The average total knee currently lasts 10-15 years before the components wear out. In some cases, worn components can be easily switched out for new ones, but revision surgery is always an experience doctors and patients want to avoid if at all possible.
Knee surgery has great potential to improve your quality of life and ensure that you can remain active and vital.
