Partial Knee Replacement

Overview

Unicompartmental knee replacement surgery, also known as partial knee replacement, is a surgical procedure designed to relieve pain and restore function in individuals suffering from severe knee arthritis affecting only one compartment of the knee joint. This procedure involves replacing only the damaged portion of the knee joint with artificial implants, leaving the healthy parts intact.

How is procedure performed?

During the surgery, Dr Shales makes an incision over the affected knee to access the damaged compartment. The damaged cartilage and bone are then removed, and the artificial implants are securely fitted into place. These implants mimic the natural shape and function of the knee joint, allowing for improved movement and reduced pain.

Preparation for procedure

Before undergoing unicompartmental knee replacement surgery, patients will typically undergo a thorough medical evaluation, including imaging tests such as X-rays and MRI scans. It is essential to follow any pre-operative instructions provided by your surgeon, which may include avoiding certain medications or adjusting existing medications.

Procedure Recovery

Following surgery, patients will spend some time in the hospital for monitoring and initial recovery. Physiotherapy will be initiated soon after surgery to help regain strength, flexibility, and mobility in the knee joint. It is crucial to follow post-operative care instructions provided by your surgeon to optimise recovery and prevent complications.

Rehabilitation plays a crucial role in the success of unicompartmental knee replacement surgery. Physiotherapy and exercise programs are tailored to each patient's specific needs and goals to improve strength, range of motion, and function in the operated knee. Consistent participation in rehabilitation exercises is essential for achieving optimal outcomes.

Risks and Complications

While unicompartmental knee replacement surgery is generally safe and effective, as with any surgical procedure, there are potential risks and complications to be aware of. These may include:

- Infection

- Bleeding

- Blot clots

- Stiffness

- Nerve damage

- Persistent pain

- Progression of arthritis -- resulting in revision surgery

Dr Shales will discuss these risks with you in detail before surgery.

Outcomes

Many patients experience significant pain relief and improved function following unicompartmental knee replacement surgery. With proper rehabilitation and adherence to post-operative guidelines, patients can expect to return to activities of daily living with reduced pain and increased mobility in the affected knee.

Conclusion

Unicompartmental knee replacement surgery is a viable treatment option for individuals suffering from severe knee arthritis localised to one compartment of the knee joint. By selectively replacing the damaged portion of the knee, this procedure offers the potential for improved pain relief and functional outcomes, allowing patients to return to a more active lifestyle.

Frequently asked questions

Here are a number of the questions we often get asked.

How long does it take to recover from unicompartmental knee replacement surgery?

Recovery time can vary depending on individual factors, but most patients can expect to see significant improvement within a few weeks to months following surgery.

How long do unicompartmental knee implants last?

While unicompartmental knee implants can provide long-lasting pain relief and function, the lifespan of the implants can vary depending on factors such as patient activity level, implant design, and overall health.

Are there any restrictions I need to follow after surgery?

Dr Shales will provide specific post-operative guidelines and restrictions based on your individual circumstances. It's essential to follow these recommendations to optimise your recovery and reduce the risk of complications.
