What is a bilateral knee replacement?

This surgical procedure replaces both knee joints with artificial implants in order to relieve severe pain and restore mobility and function. During knee replacement surgery, any damaged bone and cartilage are removed from the joint and replaced with metal, ceramic or plastic parts. If only one side of the knee is affected, it is also possible to have a partial knee replacement. Your doctor may recommend a bilateral knee replacement if you are suffering from degenerative arthritis in both knees, and physical exercises and pain relief are no longer effective.

Simultaneous bilateral surgery is when both knee joints are replaced in the same operation, but this surgery can also be performed in staged operations with a break in between. Either procedure may involve a combination of either total knee replacement or partial knee replacement. The decision to have simultaneous or staged surgery is individual to the suitability of the patient.

Is it right for me?

The aim of any treatment is to relieve pain and improve mobility. If your knee pain is no longer responding to medication or rest, and your quality of life is suffering considerably as a result, your doctor may recommend bilateral knee replacement surgery. Once you have decided to proceed with surgery, you can discuss whether to have both knees operated on simultaneously, or whether to have separate procedures. Your treating doctor will assess your suitability as a patient, taking into account your age, health and tolerance for major surgery as well as an intensive rehabilitation program.

A simultaneous bilateral knee replacement does have the advantage of convenience with a single operation and a single recovery period. But as a major procedure, it is not considered a suitable option for all patients. As with all surgery, there are risks and benefits associated with both simultaneous and staged procedures which you can discuss with your treating doctor.

How the surgery is performed

Bilateral knee replacement is a procedure where both of your knees are replaced during the same surgical session. Our expert surgeons at St Vincent's Private Hospital use advanced techniques to remove the damaged parts of your knee joints and replace them with prosthetic components. This surgery is conducted under general anaesthesia, ensuring your comfort and safety throughout the process. The goal is to alleviate pain and restore mobility in both knees simultaneously.

Preparation

Preparing for bilateral knee replacement involves several steps to ensure your safety and the success of the surgery. This includes a thorough medical evaluation, discussions about your medical history, and possibly adjusting current medications. We recommend physical exercises to strengthen your muscles pre-surgery. It's also important to arrange for assistance at home post-surgery, as your mobility will be temporarily limited. Our team will provide detailed guidelines tailored to your specific needs.

Follow up

After bilateral knee replacement, follow-up care is crucial for a successful recovery. This includes regular check-ups with your surgeon, a structured rehabilitation program, and physiotherapy sessions. Our team will monitor your progress and adjust your recovery plan as needed. You'll receive personalised advice on how you can gradually increase your activity levels and tips for a healthy recovery at home.

Total knee replacement approaches

Other knee surgeries and procedures

Staged bilateral knee replacement involves two separate surgeries, typically spaced several months apart, to replace each knee joint. This approach allows one knee to heal before the other is operated on. In contrast, simultaneous bilateral knee replacement means both knees are replaced during the same surgical session. The choice between staged and simultaneous procedures depends on various factors, including your overall health, the severity of knee damage, and personal preferences.

After bilateral knee replacement, you can expect significant relief from knee pain and improved joint function. Initially, there will be a recovery period involving hospital stay, followed by rehabilitation. You'll work with physiotherapists to regain strength and mobility. It's normal to experience some discomfort and swelling post-surgery, but this will gradually decrease as you heal.

The recovery time varies from person to person, but generally, it takes about 3-6 months to recover fully from bilateral knee replacement. This period includes hospital recovery, rehabilitation, and gradually returning to normal activities. Your commitment to physiotherapy and following post-operative care instructions play a crucial role in your recovery speed.

Kneeling after bilateral knee replacement is possible for many patients, but it may not be comfortable for everyone. It's important to wait until your surgeon gives you the go-ahead, which usually happens after your knees have sufficiently healed. Some patients find that using cushioning or knee pads helps when kneeling.

Yes, walking after bilateral knee replacement is not only possible but encouraged as part of the recovery process. Initially, you may need the assistance of a walker or crutches. Gradually, as your strength and mobility improve, you'll be able to walk more independently. Regular walking is an excellent way to aid your recovery and regain knee function.
