There is nothing pleasant about realizing that your body is not working in the way that it did before. Perhaps you thought that if you kept up with your diet and exercise, you would be able to go without serious surgery on your joints. But the fact is that if you cause damage to those joints in your early years, then you are going to pay the price at some point. That is why you may want to consider going ahead with a knee replacement or hip replacement surgery, if you are experiencing a lot of pain in those areas.
There is no shame in having to go through with a joint replacement procedure. So long as you are going to go ahead with this procedure through a top doctor in your area, you will be in very good hands. They will ensure that everything goes smoothly and that you are not experiencing any problems with this process. You will know that you are going to get the best treatment, and that your rehabilitation will be very good as well. That is how you know that you will be able to walk and exercise again without having pain.
One of the keys to any such procedure is the physical therapy that happens after the procedure is done. A lot of people assume that when you wake up after the surgery you are good to go. The fact is that you can go through the procedure and if you are not going through with the physical therapy, you can continue to have the same problems you did in the past. Surgery is going to heal what is wrong in your body in that joint, but you are going to have to exercise regularly and stretch so that you can get your muscles and ligaments back to normal.
