Preparing for Knee Replacement Surgery

If you’re planning to undergo knee replacement surgery, it’s natural to have questions. Most people who reach this stage have lived with knee pain or arthritis for a long time. Simple activities like walking, using stairs, or standing up from a chair may have slowly become more difficult.

Knowing what the surgery involves and how to prepare can help you feel more confident and less anxious.

What Happens During the Surgery

In a knee replacement procedure, the surgeon removes the damaged portions of the knee joint and replaces them with an artificial joint. Some patients need a full knee replacement, while others may only require a partial one. This decision is based on X-rays and the extent of joint damage.

Pain is a common concern. You won’t feel pain during the operation due to anaesthesia. After surgery, some discomfort is expected, especially in the first few weeks. Pain relief medication, ice therapy, and physiotherapy all play an important role in managing this phase. Most patients notice gradual improvement as healing progresses.

The ...
... surgery usually takes one to two hours. During this time, worn-out bone and cartilage are removed and replaced with metal and plastic components that allow the knee to move smoothly again.

Medical Checks Before Surgery

Before surgery, your doctor will carry out tests to ensure you’re fit for the procedure. These often include blood tests, an ECG to assess heart health, a chest X-ray, and an MRI of the knee. A dental check may also be required, as untreated infections can increase the risk of complications.

It’s important to inform your doctor about all medications and supplements you take. If you use blood thinners, you may need to stop them temporarily to reduce bleeding risk. Your doctor will guide you on the timing.

If you are overweight, even modest weight loss can help reduce stress on your new knee. A balanced diet with enough protein and essential nutrients also supports better healing.

Understanding Total Knee Replacement (TKR)

Total knee replacement is one of the most commonly performed and successful orthopaedic surgeries. In this procedure, damaged cartilage and bone are removed and replaced with medical-grade metal and plastic implants.

Doctors often recommend TKR for people with severe osteoarthritis or rheumatoid arthritis, ongoing pain that interferes with daily activities, or significant knee joint damage.

Building Strength Before Surgery

Being physically stronger before surgery often makes recovery easier. Your doctor or physiotherapist may suggest exercises to strengthen your thigh muscles, improve flexibility, and maintain knee movement. Core and upper body strength are also helpful, as you may rely on a walker or crutches during early recovery.

Low-impact activities such as swimming or cycling are good options to stay active without putting excess strain on the knee.

Preparing Your Home in Advance

Movement can be limited for a while after surgery, so preparing your home ahead of time can make recovery smoother.

Keep commonly used items within easy reach. Choose a sturdy chair with armrests to help you sit and stand safely. A raised toilet seat and shower chair can also make daily routines easier.

Remove loose rugs, clear walkways, and ensure good lighting, especially at night, to reduce the risk of falls.

Mental Preparation Matters Too

Feeling nervous before surgery is completely normal. Speak openly with your doctor about any concerns. Simple relaxation techniques, such as slow breathing or quiet reflection, can help ease anxiety.

Let family members or friends know you’ll need support during the first few weeks. Help with meals, transportation, and physiotherapy visits can make a big difference.

Life After Surgery

Recovery begins soon after the operation. You won’t be able to drive initially, so plan transportation in advance. Physiotherapy is a key part of recovery. While exercises may feel uncomfortable at first, they are essential for restoring movement and strength.

Most patients start with a walker or crutches and later move on to a cane as mobility improves. Regular follow-up visits help your doctor monitor healing and progress.
