A stiff and painful knee can make it difficult for a person to perform daily chores and activities. It can even be worse if over-the-counter medicines are no longer working. In such a case, the best long-term solution would be joint replacement surgery.
A joint replacement surgery does two things: it removes the pain and improves the function of the joint. The pain in the joint is normally caused by the friction created by the surface of the joint and the adjacent bone structure. Originally, the joint is covered with cartilage, a tissue more elastic than bone that serves as shock absorber. When the cartilage gets damaged, that’s the time actual bone surfaces start making contact, causing severe pain.
During joint replacement surgery, the damaged surface is removed and replaced with plastic or metal implants, which become the new shock absorber. Like any other type of surgery, there are certain risks involved in joint replacements. Doctors usually do not recommend such a procedure to patients with heart conditions or poorly managed diabetes.
Joint replacements are performed by certified orthopedic surgeons. They ensure that a person is fit for the procedure before recommending it. They also explain the unpredictable consequences while guaranteeing that the procedure can alleviate the constant pain. In most cases, those who have undergone full joint replacement become able to resume their daily activities once again.
