This is an operation where only a part of the knee joint is replaced. This is only possible if the wear in the joint is restricted to one compartment. The knee has 3 main compartments:

- Medial tibio-femoral compartment (inside of the knee)

- Lateral tibio-femoral compartment (outside of the knee)

- Patello-femoral compartment (behind the kneecap)

The great advantage of this type of procedure is that only the arthritic part of the joint is resected and replaced, leaving intact all the ligaments and the rest of the healthy knee. The result is a more natural feeling knee.

It is a smaller operation, via a smaller incision and the recovery is generally quicker, and the patients often report that the knee feels like their own knee.

The other advantage is that you can delay having a total knee replacement for as long as the partial replacement still functions well.

After a period of time, usually up to 10 years (sometimes less), the partial replacement becomes loose or the rest of the knee becomes arthritic, and a further operation is required. The next operation is always a Total Knee Replacement.

The main disadvantage of this type of procedure is the unpredictability of how long the prosthesis will function well, and so it is highly recommended that you seek an experienced knee surgeon regularly performing this type of surgery, to get the best possible outcome.

This is an operation where the whole of the knee joint is exposed via an incision at the front of the knee. The knee dimensions and alignment are measured, and decisions made around how much of the arthritic joint is to be removed. Usually, a minimum amount of bone is removed.

The appropriate sized implants are selected and the new knee surfaces are cemented into place using special bone “cement” (Polymethylmethacrylate – PMMA).

This is a significant operation and appropriate preoperative planning is required to ensure a safe procedure and good outcome for the patient.

TKRs usually last on average around 15 years and provide great pain relief and restoration of knee function.

This is a new evolution in the approach to total knee replacement surgery.

Recent development in robotics and computer software templating has resulted in the development of the Mako robot assisted total knee replacement.

This involves performing a preoperative CT scan of the patient’s knee. The images are loaded onto a special software which the surgeon uses to measure the level of arthritis and perform intensive and intricate preoperative planning of the surgery. This helps to ensure a highly accurate approach two joint replacement surgery.

With the MAKO system, can plan and carry out both:

• ‍Total Knee Replacement
• Partial Knee Replacement

The surgeon carries out the incisions to expose the knee joint and the robot as controlled by the surgeon to perform the bone cuts for the operation. The prosthesis is then implanted by the surgeon as usual. 

What are the advantages of Mako Robot Assisted Surgery?:

Some studies have shown:

• Less bone and soft tissue damage
• Less requirement for strong analgesics after surgery
• A reduced length of stay in hospital
• Lower requirement for inpatient physiotherapy sessions
• Less post-operative pain

‍

What are the disadvantages of Mako Robot Assisted Surgery?: 

• Requirement for CT scan pre surgery
• Slightly longer operative time
  

A robotic knee replacement is a type of knee replacement surgery in which a robot is used to assist the surgeon in performing the procedure. During the surgery, the surgeon uses a computer console to control the robot, which is equipped with specialised instruments. The robot is designed to help the surgeon position the prosthetic components of the knee with greater accuracy and precision than is possible with traditional techniques.

Robotic knee replacement surgery is typically done using a minimally invasive approach, which means that the surgeon makes smaller incisions in the skin to access the knee joint. This can result in less pain and a faster recovery time compared to traditional knee replacement surgery.

Robotic knee replacement surgery is still a relatively new technology, and it is not widely available. However, we are very pleased to be able to offer this to our patients.

It's important to discuss the potential benefits and risks of robotic knee replacement surgery with your doctor to determine whether it is a good option for you.

There are 3 types of robotic-assisted knee surgery that are currently in use:

1. Robotic-assisted total knee replacement: This is a procedure in which a robot is used to assist with the placement of implants during a total knee replacement surgery.
2. Robotic-assisted uni-condylaR knee replacement: This is a procedure in which a robot is used to assist with the placement of implants during a partial knee replacement surgery.
3. Robotic-assisted patella-femoral replacement. This is a procedure in which a robot is used to assist with the placement of implants during a patella-femoral replacement operation.
