Can I have bilateral knee replacement while taking BP, diabetes, and thyroid meds?

Dear Chhogalal Jain ji,

Yes, total knee replacement can be considered for both knees, even when the patient is taking medicines for blood pressure, diabetes and thyroid problems. However, these conditions need to be properly evaluated and controlled before surgery. Having these conditions does not automatically mean that knee replacement cannot be performed. 

The important question is whether your knee arthritis is severe enough to require replacement and whether your overall health makes surgery and anaesthesia reasonably safe.

Why Is Knee Replacement Recommended?

Long-standing knee arthritis can damage the cartilage of the knee joint, causing

• Persistent knee pain

• Stiffness

• Swelling

• Difficulty walking

• Difficulty climbing stairs

• Difficulty getting up from a chair

• Reduced ability to perform daily activities

When pain and disability continue despite medicines, physiotherapy, exercise and other non-surgical treatments, knee replacement may be considered.

What About Diabetes, Blood Pressure and Thyroid?

These conditions should not be ignored before surgery.

Diabetes

Blood sugar should be well controlled before knee replacement. Poorly controlled diabetes can increase the risk of complications, including infection around the artificial joint.

Blood Pressure

Your blood pressure should be checked and brought under good control before surgery. Continue your medicines unless the surgeon or anaesthetist specifically tells you to change or stop them.

Thyroid

Your thyroid condition and thyroid hormone levels should be reviewed before surgery. Tell the orthopaedic surgeon and anaesthetist about all thyroid medicines you are taking.

What Should You Do Before Surgery?

Take all your current medicines and medical reports to the orthopaedic surgeon. Before surgery, the medical team may assess

• Blood sugar and diabetes control

• Blood pressure

• Thyroid function

• Kidney function

• Haemoglobin

• Heart health

• Current medicines

• Fitness for anaesthesia

• Knee X-rays and severity of arthritis

Do not stop blood pressure, diabetes or thyroid medicines on your own.

If you take blood-thinning medicines, inform the surgeon well in advance. The doctor will decide whether and when they need to be adjusted before surgery.

Both Knees at the Same Time or Separately?

Both approaches can be possible. In selected patients, both knees may be replaced during the same operation, but this is not suitable for everyone. The surgeon will consider age, general health, diabetes control, heart and lung condition, fitness for anaesthesia and the severity of both knees before deciding.

For a patient with diabetes, blood-pressure and thyroid treatment, it is particularly important to discuss whether both knees should be operated on together or whether staged surgery would be safer.

Precautions Before Surgery

• Keep blood sugar within the range advised by your doctor.

• Monitor blood pressure regularly.

• Continue thyroid treatment as prescribed.

• Avoid smoking and alcohol.

• Maintain a healthy weight if possible.

• Follow the exercises recommended by your orthopaedic doctor.

• Inform the surgeon about every medicine and supplement you take.

• Treat any active infection before planned surgery.

• Do not take painkillers or supplements regularly without medical advice.

After Knee Replacement

Early movement and prescribed physiotherapy are important after surgery. They help restore knee movement and reduce the risk of complications such as blood clots. doctor also prescribe medicines to reduce blood-clot risk. 

Watch for increasing wound redness, swelling, discharge, persistent fever, severe calf pain or swelling, chest pain or sudden breathlessness and contact the treating hospital immediately if these occur.

Our Recommendation

Yes, knee replacement can be a suitable treatment option despite taking medicines for diabetes, blood pressure and thyroid, but the patient should first undergo a proper pre-operative assessment. We would recommend taking the latest knee X-rays and complete medical reports to an experienced joint-replacement orthopaedic surgeon and asking whether bilateral replacement should be done together or in separate stages.

If you share the patient's age, latest blood-sugar report, blood-pressure readings and knee X-ray findings, We can help you to connect ortho specialist.

Wishing you and your family good health always.
