80-90% of people attain a good result, which means that the knee is straight, comfortable when standing and walking, and can bend more than 90 degrees. The initial pain of the surgery improves within a week to ten days and often almost disappears within 3 weeks. Most people will feel very little pain after the first 6 months and many continue to improve for the first two years.

Most people are unable to use stairs before their knee replacement. This improves after surgery with approximately 80% being able to manage stairs after the operation.

The main problem is due to loosening from the bone over the years. The replacements will often wear out after 10-15 years.

The knee may need to be operated on again, however this is technically more difficult than the first operation and may not be as successful.
