Knee Replacement

You’ll only need a knee replacement if your knee gives you pain, stiffness, instability or loss of function that affects your daily life and activities. Arthritis damages the hard cartilage so that it becomes thin. The interlocking parts of the artificial joint allow your knee to bend while also making it more stable. Most people who have a knee replacement are over 60.

Unfortunately, some people may not be able to have a knee replacement even though their arthritis is very bad. This may be because:

• your thigh muscles are very weak and may not be able to support your new knee joint.
