The largest joints in the body, our knees allow us to do countless daily activities, such as walking, bending, turning and even standing. When they stop working, doctors can replace them, said orthopedist Ted Jefferson, D.O., at Western Baptist Hospital.

Total knee replacement offers relief to people whose knees have been damaged by some form of arthritis— most often osteoarthritis—or injury, Jefferson said.

“In the past, doctors considered the best candidates to be those between ages 60 and 75,” said Jefferson. “But in recent decades, with improvements in materials and technology, more and more people of virtually all ages have had successful knee replacement surgery.”

Jefferson said knee replacement surgery drastically lessens pain, improves daily function and enhances overall quality of life for 90 percent of patients. It now is offered as a minimally invasive procedure, meaning less recovery time, quicker healing and better outcomes for the patient.

“Knee replacement might be your best option if physical therapy, medicines or other procedures aren’t enough to control your pain,” said Jefferson. “Your doctor can help you decide if this type of surgery is right for you.”

How to Prepare for Knee Replacement

To prepare for knee replacement surgery, orthopedist Stephen Jackson, M.D., at Western Baptist Hospital, said a complete physical may be required.

“This helps your doctor determine whether you have health conditions that could interfere with the procedure,” said Jackson.

A visit to the dentist might be in order, too. While infections after knee replacement are rare, some dental problems could potentially trigger them.

Also, plan to get help with tasks such as cooking, shopping and bathing for several weeks after surgery. Before the procedure, make your home easier to navigate. Placing safety bars or rails in the shower or bath and handrails along stairways can be beneficial during the healing process.

Ask your doctor if you should do any exercises before surgery. Arm, chest and shoulder exercises may enable you to use crutches or a walker more easily. In addition, performing leg-strengthening exercises prior to surgery might bolster recovery.

After surgery, you will need to perform special exercises to rebuild muscles. You should be able to resume most normal activities within three to six weeks.
