Joint replacement can greatly improve your quality of life, allowing you to enjoy everyday activities without constant pain or discomfort. However, one of the biggest concerns following a hip or knee replacement is the risk of infection.

Fortunately, there are practical steps you can take before and after surgery to minimise this risk. By understanding how infections develop, following your healthcare team’s guidance, and making simple adjustments to your routine, you’ll set yourself up for a safer and smoother recovery.

Understanding the risk of infection after joint replacement

While modern surgical techniques and sterilisation methods are extremely effective, it’s important to remember that no procedure is entirely free of risk. Infections can occur if bacteria enter the body and settle around your new joint.

Although this is relatively rare, the consequences can be serious if not addressed promptly. Factors that may increase your infection risk include having certain medical conditions (like diabetes), having a compromised immune system, or smoking.

It’s reassuring to note that studies looking at infection prevention strategies have reported favourable outcomes when patients and healthcare providers work together to follow best practices.

For example, careful planning before surgery, can give you a clearer picture of your personal risk factors and the measures you can take to minimise them.

Pre-operative measures to reduce infection after joint replacement

A proactive approach before your operation can make a significant difference in preventing post-operative infections. Undergoing a thorough medical assessment can ensure any underlying health issues are well-controlled.

For example, if you have diabetes, keeping your blood sugar levels stable can help your body fight off infections more effectively. If you’re a smoker, reducing or quitting tobacco use before your surgery can also lower your chances of complications.

Many hospitals recommend showering or bathing with a special antibacterial soap on the day of or the night before surgery. Your care team may suggest cleaning the surgical area with disinfecting wipes, which helps decrease the amount of bacteria on your skin.

It’s also essential to make sure your home environment is ready for your return. Simple preparations like washing your bed linens, cleaning high-touch surfaces, and organising a comfortable recovery area, can create a more hygienic space that supports your recovery.

Post-operative care and lifestyle adjustments

The days and weeks after joint replacement are a critical time for preventing infection. Your surgical wound will need special attention, and you’ll receive instructions on how to keep it clean and dry.

Pay close attention to these guidelines, changing dressings as recommended, monitoring for signs of inflammation (such as redness or swelling), and avoiding activities that could expose the incision to bacteria (like swimming in public pools).

Proper nutrition, hydration, and rest also play a vital role in helping your body heal. A balanced diet rich in vitamins and minerals can support your immune system, making it easier to ward off infection. Staying hydrated helps your body function at its best, while getting enough sleep allows tissues to repair and regenerate.

Engaging in the right amount of physical therapy is equally important. Gentle exercises help maintain blood flow and flexibility around the new joint, reducing stiffness and promoting healing. However, it’s essential not to push yourself too hard. Overexertion can strain the surgical area, increasing the risk of complications. Listen to your physiotherapist’s recommendations on safe movement and gradually build up your activity level as your body recovers.

Finally, always keep an eye out for warning signs. If you notice persistent pain, fever, fluid drainage from the incision, or any unusual changes in how your joint feels, contact your healthcare team right away. Early detection and treatment can prevent a manageable issue from becoming a serious problem.
