Robot Assisted Knee Replacement

Knee replacement operations can be performed using a Mako robotic arm. Robotic assisted knee replacements enable the procedure to be tailored to your needs and performed more precisely than conventional joint replacement surgery.

Who Should Consider Robotic Assisted Knee Replacement?

Knee replacement surgery can help to relieve pain and improve mobility if your joint has become worn or damaged. The joint will be replaced with a prosthetic knee that is attached to the shin and thigh bones. Knee replacements may be needed after an injury or due to a condition such as arthritis. A total knee replacement can be performed using a robotic arm in order to protect as much of the bone as possible. Robotic assisted knee replacements can also ensure that you get the best fit and alignment for the implant so that you can recover your mobility as fully as possible.

The Procedure

Robotic assisted knee replacement surgery follows a similar procedure to a conventional knee replacement. However, the surgeon will perform the operation using a Mako robotic arm. The procedure will be carefully planned using CT scans and a 3D model of your knee joint. The surgeon will use the robotic arm to remove the damaged parts of the joint and to fix the knee implant in place. The doctor will be able to adjust the plan as needed during the procedure. The robotic arm enables the operation to be personalised to your needs and performed more accurately than is possible with conventional techniques. Once you have recovered from the operation, you will be able to recover your mobility with physiotherapy.

Risks and Benefits

If you are considering surgery, it is important to understand the risks and benefits of knee replacements, including those that are unique to robotic assisted procedures:

  • Surgery always carries a small risk of complications such as heavy bleeding, infection, damage to the nearby nerves, and blood clots. Your doctor will make sure that you understand these before you have the operation.
  • The knee implant should last for about 20 years in most patients, but it may need to be replaced at some point, which will require another operation.
  • Robotic assisted surgery is thought to reduce the risk of needing an early replacement as the artificial joint is more likely to be in the optimum position and thus reduce the forces through the knee and reduce wear.
  • Knee replacement surgery should help to improve your mobility and relieve pain or other symptoms.
  • Robotic assisted knee surgery can be tailored to your needs more effectively than conventional procedures
  • The robotic arm can carefully remove the damaged or diseased bone while preserving as much of the healthy bone as possible
  • Robotic assistance enables the implant to be positioned more accurately, which ensures that you recover your mobility as much as possible
