Total knee replacement or partial knee replacement surgeries are considered the very last resort for treating osteoarthritis. Surgery can relieve severe pain and improve physical function like the ability to walk, move from sitting to standing, and other everyday activities. Before surgery, people with knee osteoarthritis are treated with medications, exercise, weight loss, and physical therapy. It is only when these treatment options are no longer able to adequately manage someone’s pain and loss of function that surgery is considered.

So when should I get a total knee replacement surgery?

There is a lot of debate surrounding when the best time to undergo total knee replacement is. There are negative impacts of receiving surgery both too early or too late.

About 25% of people who don’t need a total knee replacement surgery were found to undergo the procedure anyways.[2] People that undergo a total knee replacement too early may not see a reduction in their pain or an improvement in their fuction after a major surgical procedure.[2] These people were also more likely to undergo a revision surgery as a result of receiving the surgery too early in life.[2]

On the contrary, about 90% of people who were identified as needing a total knee replacement surgery were found to not receive the surgery.[2] People that put off their total knee replacement too late are at risk of having physical activity limitations after their surgery, and are at a higher risk of disability and chronic disease as well.[2] Furthermore, people that delay their total knee replacement lose out on the benefits of living with less pain and more function for longer between the time of diagnosis and surgery.

There are many reasons as to why people might undergo a total knee replacement surgery too early or too late. People who were younger and living alone were found to undergo a total knee replacement too early.[2] Younger people may opt for a knee replacement earlier as they have to work, and need to be in good physical health to do so.[2] People that live alone may have more fear of losing their independence should their condition deteriorate.[2]

People who are black have an increased chance of undergoing a total knee replacement too late, this may be associated with the systematic racism present in the healthcare system in the United States.[2] Additionally, many healthcare systems may be structured so that people have to wait long periods of time before they are even able to receive knee replacement surgeries.[2]

What are my other options?

Exercise is the most effective non-surgical treatment for osteoarthritis Exercise has been found to reduce pain and improve physical function in people with mild and moderate knee osteoarthritis.[3] In fact, people with osteoarthritis who do not regularly exercise experience increased pain, disability, weight gain, comorbidities (diabetes, high blood pressure...etc.), fatigue, and depression. All of these factors can further discourage someone from exercising, which continues to lead to poorer health outcomes and worsening of their osteoarthritis.

A 2013 study found that exercise did not significantly reduce pain or improve physical function in people with severe osteoarthritis.[3] However, a more recent study found contradicting results, where people with did see reduced pain and improved physical functioning, only to a lesser degree than people with mild or moderate osteoarthritis.[5] Multiple studies have also found that people who exercised before their knee replacement surgeries were likely to have better results after their surgery, in terms of pain relief and physical functioning, and could get back to their everyday lives sooner.[1][4] In the case of severe OA exercise cannot replace a knee replacement but it can reduce pain, improve function and also improve your outcomes for your future knee replacement.


It’s important to partake in exercise before your knee replacement surgery, to ensure the best possible results afterwards, such as relief from your pain and regaining your physical activity level. However, exercise does not replace a total knee replacement surgery, and delaying this procedure can actually have negative consequences on your knee health.
