Although a knee replacement procedure can seem intimidating, it's a common and successful practice. Almost 800,000 surgeries are performed annually in the United States, with 90% of replacements still functional after 15 years. If you have knee problems due to arthritis and are curious whether they warrant this treatment, review the guide below and consult your doctor for personalized advice.

When Do You Need a Knee Replacement?

1. Arthritis Is Severe

Most people who undergo knee replacement surgery experience one of three types of arthritis. Among the different kinds, the most common is osteoarthritis. This disorder involves a gradual wearing away and deterioration of the cartilage. Less prevalent are rheumatoid arthritis, an autoimmune condition, and posttraumatic arthritis, which occurs after an injury. 

While these diseases differ in their exact mechanism, they all result in pain and reduced motion from loss of cartilage. If symptoms become severe enough, a surgeon can recommend a knee replacement.

2. Alternative Treatments Are Not Effective

Initially, nonsurgical interventions, like medication and physical therapy, can be used to treat painful knees. However, these are often ineffective because they do not address the underlying cause of your symptoms, which is cartilage erosion.

If left untreated, issues with the cartilage worsen with time, leading to intensified symptoms. In this case, a knee replacement procedure can resolve the problem and correct the diseased tissue.

3. Knee Has Changed Structurally

If alternative treatments don't work, the arthritis symptoms can lead you to walk differently than usual. As a result, the knee can gradually become deformed, which a doctor can verify with an X-ray. If that's the case, the medical provider could advise a replacement.

However, the procedure doesn't always yield perfect results. For example, if the knee has deformed to the point where it cannot straighten out completely, a replacement may be unable to correct that problem. Only a doctor can determine the right solution based on your unique needs.
