Knee Replacement Surgery
Get back in the swing of life with knee replacement
Knee pain disrupts everyday life. You want to be able to climb stairs, move around and do fun things without constant pain. Many people who have knee replacement surgery say that they wish they’d done it sooner.
Knee replacement is an elective procedure that restores function of the knee joint and relieves pain. Every year, more than one million Americans, including many right here in Indiana, return to their lives pain free, due to total joint replacement surgery.
You should consider a knee replacement if you've noticed increased pain, progressive limping, or pain that wakes you up at night. These kinds of changes indicate that knee replacement could be an option to minimize debilitating knee pain.
Who Benefits from Total Knee Replacement
People who experience the most dramatic benefits from total knee replacement are those experiencing knee pain due to:
- Osteoarthritis
- Avascular necrosis (bone loss due to insufficient blood supply)
- Bone tumor or injury
- Rheumatoid arthritis
Many people have chosen to have knee replacement surgery so they can do the things they love without pain.

Joint replacement surgery has been performed for many years. Most people who have this surgery are able to move better and have less pain after recovery. For these reasons, total joint replacement surgery has the potential to dramatically improve quality of life for many people. In 95% of cases, a new knee joint will last 20 years or longer.
Joint replacement is a major surgery. It does have some risks. It is important that you know of possible risks and complications of joint replacement surgery and discuss them with your surgeon.
Deciding on Knee Replacement
Before you have knee replacement surgery, your doctor usually wants you to have tried other options like the ones listed above. When those options haven’t helped with your pain and function, it’s time to talk about knee replacement.
First, your doctor wants to see X-rays of your knee. After examining you and viewing these images, your doctor can recommend if surgery is a good option. If you decide this is the right step, your surgery is scheduled for a time that works well for you and when you have friends or family who can help you. You also attend a pre-surgery joint replacement class to learn what to expect from surgery.
Knee replacement surgery may not be the right option if your pain is due to nerve damage or if you're experiencing loss of motion but no pain.
Non-Operative Arthritis Treatments
As with any elective surgery, your doctor will have you try non-operative alternatives before deciding on knee replacement. For knee pain, you should explore the following:
- Exercise/Conditioning
- Medication, including Tylenol and anti-inflammatories, such as Advil or Motrin
- Injections, including steroid and Synvisc and Hyalgan
- Bracing
- Acupuncture
- Weight loss
- Activity modification
- Sometimes, other knee procedures
In many cases, one or a combination of these treatments can delay or prevent the need for knee replacement surgery.
Am I Too Young for Knee Replacement?
People from age 20 to 100 have knee replacements. In the past, joint replacement was reserved for people older than 60. Technology has improved and, today, younger people can have knee replacement, remain active and expect the joint to last a long time. Your doctor will discuss with you how active you plan to be, your overall health and the expected success of your knee replacement.
What to Expect During Knee Replacement
Your surgeon will make an 8- to 10-inch incision on the front or side of your knee to access the joint. Next, the surgeon will remove any damaged bone, put the new joint in place, and close the incision with staples or stitches.
The surgery will last for about two hours. Your surgeon may use a special cement to bond the new knee parts to your healthy bone. If cement isn’t used, the artificial parts of your new joint grow together with your existing bone. You’re more likely to have an uncemented procedure if you’re younger and healthier.
