In some cases, osteoarthritis can become incredibly painful for the patient suffering from it. After a while, a doctor may determine other treatment options are no longer appropriate for the patient, and then may recommend joint replacement surgery. This surgery is very beneficial for patients with unbearable pain, patients who have only one severely affected joint, and patients who don't have other medical complications. Although the procedure used to have a much lower success rate, it has been increasing. This is attributable to two main reasons. One is artificial joints have been improved over the years. The other major reason is orthopedic surgeons have developed better and safer surgical techniques. Of course, despite improvements, there are still risks that come with any surgery, especially one as complex as joint replacement surgery. Typically, the patient will undergo physical therapy following the procedure.
