It is often said that a fake is not as good as the “original”, and this is true. So first of all, it should be noted that an artificial knee is not the “original” knee, and certainly not as good as a normal knee. Furthermore, artificial knee replacement is an elective procedure and your doctor can recommend it, so the decision is yours. However, the results of knee replacement are excellent, relieving pain, significantly improving your quality of life, and lasting for 10 or 20 years. After knee arthroplasty, most patients experience relief or reduction in pain and are able to perform daily activities more easily. More than 80% of patients are able to walk more comfortably and can even participate in sports or heavy work under the guidance of a physician. Of course, activities that exceed the capacity of the artificial joint must be avoided. In addition, 90% of patients with original knee stiffness are able to achieve better knee mobility after total knee arthroplasty. Statistics show that 10 years after surgery, 95 percent of patients are still satisfied with the results, and 15 years after surgery, more than 90 percent of patients are still satisfied. They have no knee pain and their daily activities are not limited by their knee problems. Although it is difficult to return to normal knee mobility, they are allowed to stand and walk for long periods of time with no pain. You can continue to play golf, ride a bike, swim or dance after surgery. You may feel fine after the knee replacement, but you should be advised to give up running, tennis and squatting, all of which are very demanding on the knee. If you are over 60 years of age, are not overweight, do not engage in physical labor, and do not participate in sports that are demanding on the knee joint, revision of the artificial joint is generally not necessary.
