What is revision knee replacement, aka revision knee arthroplasty?

With time, your knee replacement may not work as effectively as it should, and you may begin to feel the return of some knee discomfort and pain. All knee replacement implants have a finite lifespan, and reasons for needing revision surgery can vary from simple wear and tear of the plastic component due to use, through to loosening and infection. If you are experiencing increased pain, any swelling, reduced mobility, or stiffness, and all non-surgical methods are no longer working, your doctor may recommend you have revision knee replacement surgery to alleviate your symptoms. This simply means that the existing knee replacement part needs replacing.

Most revision knee replacements are longer and more complicated procedures than a total knee replacement and the complexity of the procedure will depend on the extent of the surgery required. In some cases, only one artificial part may need replacing. In more serious cases all three components may need replacing, along with a bone graft to rebuild the knee.

Is it right for me?

Knee replacements are designed to last for a long time, but there are many reasons why patients may need revision knee surgery after the original procedure. Younger patients who are more active are more likely to need revision surgery simply from the implant wearing out as they get older. Patients who are overweight are at risk of implant loosening, where the implant comes away from the underlying bone. Infection, injury or damage to the supporting ligaments can all prevent your current implant from working properly.

Any type of fracture of bone around the joint can also affect how the replacement works. In these instances, revision surgery may be required to remove and replace the implant.

Preparation

Before you undergo revision knee replacement surgery, your doctor will advise you on what you need to do to prepare for surgery. This may include pre-surgical assessments, adjustments to current medications, and planning for post-surgery care and rehabilitation. Additionally, organising your home for post-surgery recovery, such as arranging for assistance and making sure essential items are within easy reach, will help ensure a smoother transition post-surgery.

Follow up

Post-surgery, follow-up care is crucial for recovery and monitoring the success of the revision knee replacement. This typically involves regular physiotherapy sessions to regain strength and mobility in your knee. Your surgeon will schedule follow-up appointments to monitor your progress and address any concerns. It's also important to adhere to any lifestyle or dietary recommendations provided by your healthcare team to support your healing and overall health.

Other knee surgeries and procedures

Knee replacement revision is a surgical procedure undertaken to repair or replace a previously implanted knee prosthesis that has failed, become loose, or been damaged over time. This surgery is more complex than the initial knee replacement as it involves removing the old prosthesis and replacing it with a new one, often requiring additional techniques to address bone loss or instability.

The number of times your knee replacement can be revised depends on various factors, including your bone quality, overall health, and the condition of the surrounding tissues. Generally, each revision becomes more challenging, and the outcomes may be less predictable than the previous surgery. However, with advancements in surgical techniques and prosthesis design, multiple revisions are possible, though they are typically avoided unless absolutely necessary.

Recovery time from a knee replacement revision can vary, but it generally takes longer than the initial knee replacement. Most patients can expect a recovery period of about 3 to 6 months, though it can take up to a year to fully regain strength and function. The recovery process involves physiotherapy, gradual increase in activity, and close follow-up with the surgical team.

The length of hospital stay following a revision knee replacement can vary based on your overall health and the complexity of the surgery. Typically, patients may stay in the hospital for about 3 to 7 days. During this time, you’ll receive pain management, begin physiotherapy, and are monitored for any complications.

Yes, you are generally encouraged to walk after knee revision surgery as part of the recovery process. Walking aids such as crutches or a walker may be required initially. The ability to walk unassisted and the time it takes to do so will depend on your condition and the extent of the surgery. Early mobilisation is crucial for enhancing circulation, preventing blood clots, and promoting healing.
