Knee Replacement Surgery

Our Consultant Orthopaedic Surgeons at King’s College Hospital Dubai, have performed over 5000 Total Knee Replacement (TKR) surgeries.

Knee pain

Severe knee pain resulting from a serious injury, advanced arthritis, or degeneration of the knee cartilage is the main signal that you may be ready to benefit from a TKR. Our state-of-the-art imaging technology aids both diagnoses and long-term treatment follow up.

What happens during Knee Replacement surgery?

During TKR surgery (also known as a knee arthroplasty) the surgeon will remove damaged cartilage and bone from your kneecap, thighbone and shinbone. It will be replaced with an artificial joint (a prosthesis) made of high-grade plastic and metal

Knee replacement surgery at King’s – What can you expect.

Before surgery

You will be clinically evaluated to ensure there are no problems that may complicate the procedure. This will include blood tests, a chest X-ray, a knee X-ray and an ECG.

Prior to the surgery you will have a consultation with one of the King’s anaesthesia team, to determine if you would prefer general anaesthesia, or spinal anaesthesia. You may be given a nerve block around the knee and will administered antibiotics to prevent post surgical infection, and blood thinners to prevent blood cuts (Deep Vein Thrombosis).

During Surgery

Damaged cartilage is removed along with a small amount of bone. They are replaced with metal components to recreate the surface of the joint.  Dependent on your case, the under surface of the knee cap (called the patella) maybe cut and resurfaced.  To ensure a smooth gliding surface between the metal components, a plastic spacer is inserted between them.

After the surgery

Normally you would stay in the hospital for at least 3 days after the surgery. You’ll be prescribed medicines to both prevent blood clots post-surgery, and to manage any pain you experience.  Your rehabilitation plan begins almost immediately following the surgery. A King’s physiotherapist will provide instructions on exercises to complete both in the hospital and at home.
