Knee replacement surgery is a highly effective procedure that can significantly improve mobility and reduce pain for those suffering with severe knee arthritis. However, it’s natural to wonder if you can damage a knee replacement.

While knee replacements are designed to be durable and long-lasting, certain activities and conditions can put the new joint at risk.

Here, we’ll explore whether you can damage a knee replacement, what the potential risks are, and how you can protect your new knee for years to come.

Risks of damaging a knee replacement

Knee replacements are engineered to withstand a significant amount of stress, but they aren’t indestructible. Over time, wear and tear, excessive strain, or injury can damage the prosthetic joint.

A study looking at the main causes of revision surgery for knee replacements found that pain, infection, and instability were the top reasons for patients needing additional surgery. These issues can occur due to trauma to the knee, improper use of the joint, or complications following the initial surgery.

For example, high-impact activities such as running, jumping, or heavy lifting can put excessive strain on the knee replacement, leading to wear and tear on the prosthetic components. This can result in loosening or damage to the implant, which may cause pain or instability.

Accidents such as falls or direct blows to the knee can also damage the replacement, potentially requiring revision surgery to correct the issue.

Protecting your knee replacement

To ensure your knee replacement lasts, it’s important to follow specific guidelines and take precautions to protect the joint.

Here are some key strategies to keep your knee replacement in good condition:

Stick to low-impact activities

One of the best ways to protect your knee replacement is to focus on low-impact activities that minimise stress on the joint. Walking, swimming, cycling, and using an elliptical machine are excellent options for staying active without putting undue strain on your knee. These activities help maintain joint mobility, strengthen the muscles around the knee, and promote overall cardiovascular health.

Avoid high-impact sports or activities that involve running, jumping, or sudden changes in direction, as these can increase the risk of damaging your knee replacement.
If you’re unsure whether a specific activity is safe, consult your orthopaedic surgeon or physical therapist for guidance.

Strengthen and stabilise

Maintaining strong muscles around the knee joint is essential for protecting your knee replacement. Strengthening exercises, particularly those targeting the quadriceps, hamstrings, and calf muscles, can provide additional support and stability to the joint.

A well-structured physical therapy program can help you build strength gradually and safely, reducing the risk of injury or damage.

Monitor for signs of trouble

Even with the best care, it’s important to stay vigilant for any signs of damage with your knee replacement. Persistent pain, swelling, redness, or a feeling of instability in the joint could indicate an issue. For example, infection, implant loosening, or mechanical failure.

Regular follow-up appointments with your surgeon are important for monitoring the condition of your knee replacement. During these visits, they can assess the joint’s function, check for any signs of wear or damage, and make recommendations for maintaining the health of your knee.

When to Seek Help

If you experience any concerning symptoms or suspect that you may have damaged your knee replacement, it’s important to seek medical advice as soon as possible.

Early intervention can prevent minor issues from becoming more serious and may help avoid the need for revision surgery. Your surgeon can perform imaging studies, such as X-rays or MRIs, to evaluate the condition of your knee replacement and determine the best course of action.
